Step one: Find out if your Mac can handle it

Not all Macs are eligible for memory upgrades, or at least not ones you can perform easily at home. Some might already be equipped with their maximum supported memory, and some might have more difficult to replace memory kits, like the MacBook Air does, for instance. But in general, you can find out if your Mac could take on more memory by checking your system stats.

In Lion, this is easy. Go to the Apple menu, click “About this Mac,” and then click “More Info…” Then, click the “Memory” tab along the top and it’ll show you how much memory you currently have installed, and the capacity of each individual module. In my example, I have 4 x 4 GB modules installed on my iMac, which is the most this model officially supports. Many base configuration models of iMacs currently available ship with two slots free, as mine did before I upgraded.

To find out the maximum memory your model supports, you can do two things. First, click the link in that Memory information page that says “Memory Upgrade Instructions” to be taken to the relevant Apple support site for your computer. So long as you know when your computer was released, you can find all the information you need, including Apple’s maximum memory capacity for your specific model here. If you need to find when your Mac was released, check our guide for finding that out.

You can also take a second option, which is to visit OWC, find your Mac of choice under the “Memory” section and see what options the site provides. OWC actually offers kits that provide memory in capacities that often exceed Apple’s official supported specs, but will still work fine with your hardware.

Step two: Figure how much memory you need to upgrade

OWC is a great resource for figuring out how much RAM you need to purchase to upgrade. Navigate to the Memory section on the OWC homepage, then find your model of computer. Now, the site will provide you with a number of options for memory upgrades and replacements. OWC had basically done the thinking for you, so you can just click on a combo package greater than your current memory configuration and not worry about whether or not the modules will work with each other or your machine.

The other benefit of going through OWC is that they have very fair prices, and they even offer rebate pricing on the memory that shipped with your Apple computer. You won’t get much, but it’s more than you’d make by throwing your old RAM in the garbage.

Step three: Install the RAM

Following Apple’s installation guides is the best way to go about replacing your RAM. Here are links to the instructions for upgrading iMac memory, Mac mini memory, MacBook Pro memory, and MacBook memory. It’s not difficult and requires a minimum of tools, but you will need a small screwdriver, like one you’d use for eyeglasses repair, in order to replace memory on iMacs and MacBooks.

Step four: Enjoy considerable performance boosts

When I upgraded my 2011 iMac from its basic 4 GB of memory to 16 GB, it was definitely like getting a new machine. Things never grind to a halt anymore; I can run Photoshop alongside other demanding applications without major slow-downs; and my computer seldom requires an actual restart or power-down to get things moving smoothly again. The entire upgrade cost me less than $100, too.

If you love your Mac but find yourself less than impressed with its performance lately, a memory boost could be just the thing to put the spark back in your relationship.

The MacBook Air was the only notebook that saw increased shipments during the quarter, according to Digitimes Research, which said on Monday that notebook shipments slowed by 8.7 percent sequentially to 48.59 million units worldwide during the quarter.

In Apple’s last quarterly earnings report, it reported 4.89 million Macs sold, meaning if we use Digitimes’ estimate of 1 million MacBook Airs sold, the notebook represented roughly 20 percent of the total. We know Apple’s iMac is also performing well, but it’s logical to assume the Air is growing in influence in terms of the overall Mac picture. Expect that trend to continue, since analysts expect the so-called Ultrabook category to explode in the next six years.

Apple doesn’t usually break out sales of individual Mac lines from the overall Mac category total, but it will still be interesting to see if it has any official comment on the success of the Air during its quarterly earnings conference call on Jan. 24.

• A clouded view of Google Music
• Will cloud computing push the BRIC market to the front?
• New challenges for the IT organization

“Thunderbolt” is turning up in my inbox quite a bit, with pitches for Thunderbolt docks, drives, adapters and expansion devices. No doubt that is helped in part by the news that Thunderbolt will be coming to computers from select PC vendors, including Acer and Asus, arriving sometime in the second quarter of this year. But it also helps that nearly all of Apple’s line of computers, including its popular iMac desktop, have put Thunderbolt into the hands of a much broader potential market of peripheral shoppers.

Some of the products on tap include more-traditional external drives than we have seen to date, with SSD drives from usual-suspect Mac accessory makers like Elgato and OCZ. These drives still are not exactly aimed at the average computer user, since they will reportedly come in starting at $400 for storage sizes of 128 GB and up. But they should be a hit with pro video and audio editors, as well as the semi-pro or serious hobbyist crowd.

Much more interesting to mainstream Mac users are devices like the Belkin Thunderbolt Express Dock, which should arrive in September and will boast three USB 2.0 ports, one Firewire 800 connection, a Gigabit Ethernet port, one 3.5 mm audio jack and two Thunderbolt ports. Basically, it provides a lot of what the Apple Thunderbolt Display offers but without the screen and for a heavily reduced price of $299. For users who want a quick and easy docking solution for plug-and-play home theater connectivity, this is a good solution and cheaper than many receivers.

Another solution that average users might get some use from is the Thunderbolt eSATA hub shown off by LaCie at CES. It features connections for up to two eSATA-connected drives via one Thunderbolt port, along with a second Thunderbolt port for daisy-chaining. ESATA drives are loads cheaper than their native Thunderbolt equivalents, and with top speeds of 6 Gbps, eSATA is still plenty fast for most users. No word on pricing yet, but this one is coming soon: within the first quarter of 2012.

LaCie also unveiled a dual 3.5-inch drive enclosure called the 2Big that hooks up via Thunderbolt, with size offerings of up to 8 TB of total storage planned. I wouldn’t expect this one to be within the average consumer’s price range, but the more the tech is adopted at all levels, the better the potential of lower prices across the board.

Some of these items are still pro-focused and the others aren’t exactly cheap, but at least accessory makers finally seem to be embracing the possibilities that Thunderbolt offers. With cheaper third-party cables and maybe some USB 3.0 cross-compatibility, this should be the year we see the Thunderbolt port get used for more than just Mini DisplayPort connections.

Doing it before it was cool

The iMac was an all-in-one long before the form factor was popular, although it arrived much later than its own predecessor, the original Macintosh computer. Still, at the time the iMac arrived, the competition was all about separate towers and monitors. All-in-ones had trade-offs that seemed considerable at the time, including fewer customization options and no opportunity to really get into the high-performance range of personal computing.

Fast-forward to today, 14 years after the introduction of the first iMac, and it is the computer with the lion’s share of the hottest growth area in desktop computing. According to DisplaySearch, as reported by Bloomberg on Wednesday, the iMac accounts for 32.9 percent of the all-in-one desktop market, which itself grew 39 percent over the course of 2011 to 14.5 million shipments worldwide. DisplaySearch believes that the market will reach 23.3 million units by 2014, and Apple looks likely to lead the pack, since its next-closest competitor is Lenovo, with 22.7 percent of all-in-one sales.

Early investment pays later dividends

Apple doesn’t always strike a vein when it comes to early, unusual designs for its computers. The G4 Cube is a prime example. But that doesn’t mean they don’t bear fruit. The Cube formed the groundwork for the Mac mini, which succeeds as an HTPC and an inexpensive Mac desktop option. Likewise, the early MacBook Air, which was expensive, somewhat underpowered and mostly admired from afar, paved the way for the current generation of sleek, fast, awesome general-use machines.

Apple worked out its ultraportable teething issues early, while competitors either looked on in disbelief that anyone would want such a device (its downsides vs. traditional notebooks were similar to the iMac’s flaws regarding user customization and repairs) or offered even more half-baked attempts at competing, like Dell’s Adamo. The first iteration of the MacBook Air meant Apple was ready to come back cheaper, faster and stronger.

Playing catch-up

Now Intel is prompting other notebook manufacturers to jump in late and try to capitalize on the demand for ultraportables. CES pitches are littered with the term, and it seems like every PC maker is planning an Air-like notebook for release in the near term. But the iMac’s doppelgängers haven’t managed to dethrone it, and I highly doubt we will see the notebook market behave very differently.

With both the iMac and the MacBook Air, Apple managed to successfully skate to where the puck’s going to be, and in doing so it has put itself at the fore of growth areas in overall markets (desktop and notebook PCs) that are otherwise sluggish. For users, that means both the iMac and the Air will be among Apple’s most exciting products to watch in 2012 and beyond.

• The future of notebooks: Following in the footsteps of the MacBook Air
• Facebook’s IPO filing: ideas and implications

iPhone

Apple’s next iPhone is one many probably feel we’ve already seen in previews, since the rumor mill prior to the release of the iPhone 4S was focused more on the so-called iPhone 5. A lot of what was said about that device should probably come to pass when we do get a new iPhone next year, which Apple could well call the iPhone 5.

A release in fall is probably in the cards, since Apple would gain little by releasing a new iPhone in the early summer so soon after unveiling the iPhone 4S, so it’s hard to pin down anything definite about the device at this point; a lot can change in mobile in nearly a year, after all. But there are a few safe bets regarding Apple’s next smartphone.

First, expect an A6 processor, possibly quad-core, powering the device. Also, a larger screen and a new physical case design are almost guaranteed. I don’t think Apple would go the route of the Android-makers with anything gigantic, but a respectable 4-inch display seems likely. And while LTE still isn’t a guarantee, it’s a good bet for 2012. Near-field communication (NFC) is less certain to make the cut, since that tech still has a long way to go before (if) it goes mainstream.

iPod

Making predictions about Apple’s iPod line is definitely tough. The media player got virtually no changes in 2011 compared to 2010, and its impact on Apple’s overall revenue picture continues to dwindle. The iPod touch is still an important part of the lineup, but even its future might become a question sometime in the next couple of years.

In 2012, I see Apple finally putting its iPod classic to rest, and maybe the shuffle, too. The iPod touch will likely get the spec bump it missed this year, bringing it closer to the current iPhone 4S in terms of wireless radios and processing power, and possibly a physical redesign, too. The real question mark, and maybe Apple’s greatest opportunity to shake up the media player market, is the iPod nano.

Users have been looking for an update that brings Bluetooth on-board with the diminutive nano, making it compatible with wireless headphones (better when worn on the wrist) and possibly enabling a live data connection between it and the iPhone. I suspect that Apple skipped a proper update for the nano this year because it’s actually working on making the nano the perfect connected companion for the iPhone, thanks to Bluetooth 4.0 tech, but we’ll see in 2012 whether or not that’s the case.

iPad

Rumors about the iPad 3 are already swirling, since it seems on track for an early 2012 release. I think we’ll see it arrive around the same time as last year’s iPad 2, so between February and March, complete with the Retina Display users have been looking for since the iPhone 4′s release.

What else will the iPad 3 offer? That’s a good question, and one that hasn’t really been addressed all that much in early reports. Its features will be dictated largely by what the market demands, which shouldn’t be much judging by the current tablet market picture. In 2011, Apple ruled the tablet market without a real competitor in sight. In 2012, it will have low-cost alternatives nipping at its heels, but it still isn’t looking at any competitors who are truly shaking up the space.

As a result, I’d expect to see an iPad 3 that resembles its predecessor in most regards, with the aforementioned improved screen, as well as a slimmer design and maybe a longer lasting battery. Apple has the right recipe for success in other regards, and the iPad 3 isn’t really crying out for camera improvements or additional wireless tech. Adoption of Bluetooth 4.0 is probably also on tap, as well as an upgraded A6 processor, but I wouldn’t expect much else.

Instead of making dramatic changes or additions to the iPad, expect Apple to offer a low-cost option in the form of the iPad 2, likely limited to either 8 or 16 GB of onboard storage. And as much as I and Kevin admire the smaller, 7-inch form factor, I think Apple might keep that one in reserve for at least another year.

Macs

In 2012, iDevices won’t be the only devices getting big upgrades. Apple’s Mac division is still a big revenue driver for the company, and in the new year I expect them to focus on the products that will have the biggest role in the future of computing. The MacBook Air is the crucial device here, but iMacs, too, should be in for big changes.

The MacBook Air is Apple’s most forward-looking Mac, and it has plenty of room to grow. In 2011, the 11- and 13-inch form factors got even better thanks to much-needed processor upgrades and the addition of Thunderbolt tech. In 2012, I expect Apple to expand the line as it moves to push aside the MacBook Pro in terms of its importance to Apple’s notebook offerings. So a 15-inch Air is likely, as well as more substantial improvements to the 11- and 13-inch devices, aimed at shoring up their remaining weaknesses: battery life and storage. Higher resolution displays are another definite possibility.

As Apple’s strongest desktop product, expect iMacs to get significant updates in 2012, both externally and on the inside, too. The current iMac case design is getting a little long in the tooth, and is overdue for an update. Intel has new processors that will likely make their way into Macs in the works, and we should see them in the second quarter of 2012, so expect new iMacs around then, too. Other changes might include high-res displays like those that could make their way to the notebook line, and solid state storage as the default option on some models.

As to the rest of the Mac line, I’d expect to see upgrades for the Mac mini, but not necessarily any big improvements for the Mac Pro. Apple is clearly focusing on consumer products, and it could let its more powerful desktops languish again as a result.

Apple TV

It’s the last big question mark for Apple’s 2012 plans, the mythical iTV. I think we’ll see Apple make its move here, and introduce a television set late in the year, complete with a full App Store, Siri controls and iCloud support. Whether or not we’ll see its set-top Apple TV gets a similar upgrade strikes me as less certain, but since it could act as a gateway device the way the iPod touch does for the iPhone and iPad, I think we’ll see that, too.

This is the rough roadmap I see in place for Apple’s 2012 product plans. Predicting Apple’s plans is likely a fool’s game, but that doesn’t mean it isn’t fun. Let us know what you think is coming out of Cupertino in the comments.

• Connected world: the consumer technology revolution
• Flash analysis: Steve Jobs
• 2012: Data, spectrum and the race to LTE

Bloomberg BusinessWeek has a great story out on Friday illustrating the massive pricing, manufacturing and shipping advantages that Apple gets from having one of the most successfully managed supply chains in the world. Reading it, you see how having lots of money frees Apple up to do things other companies either can’t or won’t.

The report includes interesting details, like how Apple made that little green light appear next to the webcam in your MacBook. It was a manufacturing challenge that required $250,000 laser machines to cut tiny holes through metal, so Apple bought “hundreds of them.”

There’s also the tale of how Steve Jobs bought out all air freight for Christmas 1998:

To ensure that the company’s new, translucent blue iMacs would be widely available at Christmas the following year, Jobs paid $50 million to buy up all the available holiday air freight space, says John Martin, a logistics executive who worked with Jobs to arrange the flights. The move handicapped rivals such as Compaq that later wanted to book air transport.

The report illustrates two of the things that set Apple apart from its competitors in ways that are invisible to most of its customers: money and attention to detail. It’s all of those billions in the bank that give Apple the freedom to lavish gobs of attention on everything from massive manufacturing problems to insanely small but critical details. Some of the things the company does with that freedom range from buying out the world’s supply of smartphone displays to Senior VP of Industrial Design Jonathan Ive and some of his team staying near a manufacturer’s facility in China “for months” to closely monitor the design manufacturing and prototyping process for future products.

For next year, Apple appears to be pursuing the same tactics. It has already said via its annual report to the SEC that it will spend “$7.1 billion for product tooling and manufacturing process equipment.”

Locking down the supply chain is clearly a spending strategy that has proven itself. But it will be interesting to see how or if Tim Cook, Apple’s new CEO and longtime supply-chain guru, will continue to use the company’s cash in other ways outside the strategy approved by Jobs. Jobs turned Apple into an extremely conservative company when it came to its spending and investments and resisted any calls for investor dividends or share buybacks. Cook, however, has indicated that he and Jobs differ slightly in their philosophies. During the company earnings call last month, Cook declared:

I’m not religious about holding cash or not holding it. I’m religious about a lot of things but not that one. We’ll continually ask ourselves what’s in Apple’s best interest. So it’s a topic for the board on an ongoing basis.

Macs retain higher overall resale values than many other PCs, but they don’t last forever. But how do you know when to act? What are the symptoms of impeding Mac death or obsolescence, and when is a good time to consider replacing an old Mac with a new one?  The following seven points should help you make an educated decision about whether or not to invest in one of the new MacBook Pros unveiled Monday, or any other new Mac for that matter.

1. Will not run OS X Lion (or Snow Leopard). In the past, if you had a Mac running an older version of OS X, you could keep it running for a long time without much issue. But iCloud’s minimum specs have changed that. Your Mac must have an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor to run Lion 10.7.2 which is required to use iCloud on a Mac. If you’re not certain your Mac meets these requirements, you can easily identify exactly what Mac you have and get the specs from there. Users hoping to update to iCloud from MobileMe will need a newer Mac, and those hoping to stay on top of what could become the core of Apple’s business will also want to upgrade.

Not everyone needs the convenience features of iCloud, but you should note that Apple has also stopped releasing security updates for older Macs as well.  To play it safe, you may need to have a Mac that can at least run Snow Leopard.

2. Battery no longer keeps its charge. While certainly not the primary reason to get rid of a MacBook that still works when plugged in, it’s a sign that you may be getting near the end of your machine’s useful life.  Apple does have a battery replacement program, even for MacBooks that do not user-accessible batteries, but the cost of replacing a battery can run anywhere from $130 to $180, and if your battery is past its prime, other system components might be nearing their end, too. It may be time to consider turning that laptop into a desktop, and get a new MacBook.

3. Most-used apps are sluggish. New software tends to get bigger and more demanding with time. With each new update comes a lot more features. These may not be features you need or care about, but sometimes they’re required in order to maintain compatibility with a particular file format. You can always try sliding back to an earlier version to preserver performance, but if apps you use time and time again are making your computer slow or unusable, it’s probably time to look for something new.

4. An iPad outperforms your Mac. It may surprise you to learn that the current iPad 2′s geek bench scores are about as high as the Mac mini G4′s scores from 2005. You could try to clean out your Mac, free up some hard drive space, or even add some memory or a solid state drive to help and improve performance. But at the end of the day, there is a limit to the gains in performance you can squeeze out of older hardware, and the cost of doing so might outweigh the benefit.

5. Difficult-to-replace component has failed. If you’re not comfortable replacing the internal components of you Mac yourself, service prices can become cost-prohibitive when compared to buying a new Mac.  You may also end up being very disappointed following a major upgrade when something else goes wrong, like a hard drive failure.  With MacBooks especially, when one part starts to fail, the rest are likely not too far from failing as well.

6. The Mac you want was just updated. Following the rumors about possible Apple product updates can become more obsession than hobby.  I have looked toward’s MacRumor’s Buyer’s Guide for years now in an effort to track down when a particular product is going to be updated.  The simplest rule to follow, however, is that if you need a new Mac, buy a new Mac. But if your need happens to coincide with a fresh product update, don’t hesitate.

7. You own a PC, but all your mobile devices are Apple. Like works best with like, and that’s particularly true of Apple products. Apple has a great guide to help with the transition from a PC to a Mac.  And with Apple’s Boot Camp, VMware Fusion or Parallels, you can keep on using Windows on a Mac if you like.

• CES 2012: a recap and analysis
• The future of notebooks: Following in the footsteps of the MacBook Air
• Mobile Q2: Smartphone growth surges; iPad’s rule continues

Magma’s three-slot expansion chassis for Thunderbolt, the ExpressBox 3T announced by the company on Wednesday, is a perfect example of how Intel’s high-speed I/O port, which ships on nearly all new Macs, could bring back a greater range of customization options for owners of Apple computers. The accessory will allow you to use any PCIe 2.0 cards with Thunderbolt-equipped Macs, including video capture devices, media transcoding tools and high-speed data storage.

The ExpressBox 3T can be daisy-chained with up to six Thunderbolt devices, including the new 27-inch Cinema Display that Apple just recently began shipping to stores. It also could mean that PCIe graphics cards will let less powerful machines like the MacBook Air keep up with higher end devices for gaming and video editing applications.

It’s another step along the path of Thunderbolt allowing Mac notebooks to become powerful workstations through single-cable plug-in solutions, something which can’t come fast enough in my opinion. Portable computers already account for the bulk of PC sales, and if tech like Thunderbolt can ensure that we can have portability without sacrificing power, storage or speed when settling in to performing demanding tasks, we should be able to move closer still to Jobs’ Post-PC era.

Magma hasn’t announced pricing or availability info for the ExpressBox 3T yet, but the company will be showing off the device, and possibly releasing more information at the Intel Developer Forum in San Francisco, which runs Sept. 13 – 15. Sonnet, which makes the upcoming ExpressCard/34 Thunderbolt adapter, has also announced PCIe expansion chassis products, but no details about its release timeline have yet been unveiled. Let’s hope they all hurry up and get here so we can see what Thunderbolt is really capable of.

1. Create a service-only account

Often repair work involves administrator-level access to your Mac’s operating system. While I’ve never heard about privacy violations at Apple Authorized Service Providers, I like putting an extra barrier to protect my personal data, since I’ll sheepishly admit my account password is used in a few other places, and I’d rather nobody know it.

For added protection, I have another administrator account prior to sending my Mac in for service. An extra administrator account is good for testing purposes, so I already have one. If you don’t, then go to System Preferences, and then to Accounts and click the plus button and under “New Account.” choose “Administrator.” Create a full name and unique password and then click “Create Account.”

When checking in your computer at the repair shop, give them this password. Yes, your original account’s password could be reset and your data read, but at least this makes it a bit more difficult to do so. Even if your primary account’s password is reset, they still won’t have easy access to your keychain or be able to find out where else you use that admin password.

Now that your Mac is safely backed up and ready for service, here are two tips for an often overlooked part of the job — physically transporting your Mac.

2. Dress your iMac in a t-shirt

The iMac’s screen in particular can be easily scratched when lifting it in and out of the car. Shirt buttons and jewelry are common items that could cause scratches on your person, too. A large towel is a common protector for transport, but it’s difficult to keep that in place. My solution is an old t-shirt. If your screen size exceeds your shirt size, go to a thrift store and pick up an XL. Old shirts tend to be extremely soft and stretch easily, thereby protecting your iMac screen and keeping that protection in place during transit. The bonus is that your computer looks absolutely adorable.

Once you’ve got the T-shirt wrapped around the iMac, lift it carefully, making sure to grasp it firmly with two hands at the bottom and press the protected screen against your body. Don’t try to carry it by the stand. Unless you’re a weightlifter with unusually long arms, avoid carrying an iMac under one arm.

3. Keep it in the backseat

Just like people do with their other most precious cargo (ie., children and pets), keep the Mac in the backseat. Have the screen face backwards and strap it in with the shoulder and waist restraints. I typically place the shoulder strap over the back of the iMac and then use the waist restraint close to the base. This will not keep it in place as well as it will a child in case of an accident, but it serves to slow the Mac down, and if it does hit the back of the passenger seat, the screen is less likely to crack and the hard drive is less likely to get jostled. For an extra ounce of prevention, I push the passenger seat as far back as I can and brace it with a pillow if needed. This will also help if you have to make a sudden stop, or if you hit a few potholes long the way.

Any other tips for getting your injured Mac to and from service-related visits?

1. Know the computer’s serial number

Apple products are hot on college campuses, and can easily get stolen. Once stolen, it’s hard to retrieve your serial number after the fact, and it’s one of the first things a police officer will ask about. To obtain this information, go to the Apple () menu in the upper left hand corner, choose “About This Mac” and then click twice on the OS Version and the serial number will appear. Both student and parent should keep a copy of this information.

2. Know the computer’s warranty expiration and make sure Apple’s info is correct

Most Apple products have a one year warranty, extended to three years by AppleCare. Generally if you purchase both the computer and AppleCare at the same time directly from Apple, your AppleCare will be registered. It’s important to know if it was registered properly and the expiration date is correct before a problem develops. Go to http://support.apple.com and then click “Check Your Service & Support Coverage” in order to find out when the warranty expires. If this information is incorrect, contact Apple to get it corrected. Typically you need to fax them the receipt if there’s a discrepancy.

3. Get AppleCare if you don’t already have it

AppleCare is really a great value, especially for college students. Not only does it cover hardware failures, but it also gives you three years of phone support. That support will come in handy when a paper is due and you can’t figure out how to get iWork to play ball.

If you didn’t purchase AppleCare when you purchased your Mac, you can purchase it at anytime during the initial one-year warranty period. AppleCare is highly discounted in the educational market, either directly from Apple or from campus bookstores.

4. Insure your Mac against loss

Even if your Mac isn’t stolen, an inebriated roommate, an out-of-hand party, or plain carelessness can result in a damaged Mac. The two most common problems I see are liquid spills and laptops being dropped. Neither of these are covered by Apple’s original or extended warranty.

Most homeowners or renter’s insurance companies will allow you to specifically “schedule” a student’s computer while at the dorm. Typically this costs just a few dollars a year and results in a lower deductible and protection against more perils. Before you have problems is the time to talk with your insurance agent about it.

5. Bring a pound of uncooked rice

No this isn’t for an emergency late night dinner; that’s what ramen is for. Liquid spills are common in college environments, and the best known remedy for that is a bag of uncooked rice. Not instant rice, but the inexpensive uncooked plain white rice. Should a spill occur, immediately cut power to the computer and remove the battery. If the battery can’t be removed, shut it down. Put the device in a sealed container (typically a trash bag) with that uncooked bag of rice and wait 48 hours before trying to turn it on. The device may be okay after that. Though I shouldn’t have to say it, it is advisable to throw away the rice when you’re through.

6. Time Machine is required, but is just a first step

College is a significant investment, and a late or missed assignment can be the difference between passing a class and failing. Time Machine is a quick and effective primary backup system that comes with every Mac running Leopard or above, and enabling it will help you prevent delays due to data corruption.

However it really isn’t enough — again, college have a way of attracting “accidents.” If the Time Machine drive is sitting next to the computer, it could get damaged or go missing along with the computer. Students who use portable computers may go days at a time without connecting to their Time Machine drives, too. For the average going rate of $50 a year, I highly recommend that you buy an online and offsite backup solution. Read my recent articles for recommendations.

7. Know where to take your Mac when problems arise

In those years at college, a computer problem is likely to develop that may or may not be covered by Apple’s warranty. Before a problem occurs, it’s good to know who to call for Mac help. The obvious choice might be a local Apple retail store, but that might be far away, and in college, time is of the essence. Many campuses have college bookstores that also provide Apple warranty service, but you need to ask first. Additionally, you can use Apple’s Authorized Service Provider locator to find the closest repair center. If you have a choice between more than one, it’s a good idea to get to know them. Just ask a few questions and find out their procedures and turn around time.

8. Bring all recovery media that came with the Mac (if applicable)

Although Lion has recovery over the Internet, older Macs still need those DVDs or flash drives in order to reinstall or repair the operating system. These are typically in the box that came with the Mac and are often overlooked. When you call for support, the friendly Apple support technician will be expecting these to be close at hand. This can avoid a trip to a service provider if the problem can be diagnosed or repaired with a restore or reinstall.

9. Turn off automatic software updates

Although it’s rare, a software update can introduce new problems to a system. A recent example are numerous problems that came with 10.6.8 — enough that Apple introduced 10.6.8 v1.1. Apple eventually fixes problems with later software updates, but running software update right before a paper is due is a bad idea. Better to plan updates right before a visit home or scheduled downtime. Be sure if you don’t already know your Administrator password, you find it out now. You’ll need that for troubleshooting and updates.

10. Have a spare power adapter

This tip is for laptop users. Inevitably in the hustle and bustle of going about your studies, a power adapter is going to be left in class, at home, or at the coffee shop. A nice $1,000 + laptop can be rendered completely useless by the lack of a simple power adapter. Having a spare one can give you time to get a new one or retrieve your old one. I generally recommend keeping one at your residence, plugged in, and one in your laptop bag. If you lose the laptop bag, you can always retrieve the one from your residence.

Those are ten handy tips to make sure that you and your child never have to tell the prof “the computer ate my homework.” Got any others to add to the list?
