Snow Leopard: An Even Better Leopard

In between new notebooks and fawning over the iPhone, Bertrand Serlet got up on stage to talk about Snow Leopard, the next release of Mac OS X. Apple (s aapl) took a few digs at Microsoft (s msft) for stumbling with Windows Vista and trying to play catch-up with Windows 7. The picture that our friends in Cupertino are trying to paint is that Leopard has been a huge success and that Snow Leopard will be even better. After listening to the keynote, I find that I have to agree. I am over the moon about the changes coming to the Mac OS.


Apple is justifiably proud of Mac OS X and the excellent combination of power and usability in Leopard. Serlet was quick to point out that in this release, Apple is hoping to build on their success with Leopard and add refinements that will make it even better. There are so many refinements that I will not attempt to list them all here, but will instead refer you to Apple’s page about the refinements in Snow Leopard (be sure to click on the “even more refinements” link at the bottom of the page to get even more details).

Of all these improvements, I am most excited about three of them: Finder, Speed, and Disk Eject.

The new Finder is completely rewritten as a Cocoa native application, built with 64-bit code and Grand Central Dispatch support. This should make the Finder more responsive because it will execute tasks faster and also be able to take advantage of the multiprocessing prowess of Grand Central Dispatch to offload background tasks efficiently to idle processors. Apple says that some operations like icon preview refreshes are up to 1.7x faster. This new Finder is going to breath new life into your computer by making it more responsive.

There are other speed improvements all over Snow Leopard. Time Machine backups are faster. Waking up from sleep, shutting down, and joining a wireless network are all faster. Even installing Mac OS X is faster with Snow Leopard. Just like Maverick and Goose, I feel the need… the need for speed. And Snow Leopard delivers.

eject_icon20090608And lastly, I am thrilled about the more reliable disk ejection in Snow Leopard. 10.6 will reduce the frequency with which the OS will prevent you from ejecting a disk, and more importantly, it will tell you which application is causing the OS to keep the disk mounted. It’s a small thing, but I cannot tell you how many times I have had to reboot rather than figure out what is holding on to my external hard drive.

New Technologies

64bit_icon20090608Snow Leopard is fully 64-bit, along with a number of the included applications. Moving from 32-bits to 64 means that the addressable memory space is increased to almost 16 billion GB of RAM. This ungodly number means that you do not have to worry about software limiting the amount of RAM that can be used. In the short term, we still have to live with the hardware limits of Macintosh computers, but these will improve over time (as the new MacBook Pro’s demonstrate with an increase to 8GB RAM). And 64-bit goodness also means that some instructions will actually get processed faster on the 64-bit CPU’s that all Macs are built on. More interesting than the RAM limits of incremental performance gains, the new 64-bit memory allocation routines in Snow Leopard are also more secure and less prone to injection attacks.

gcd_icon20090608Grand Central Dispatch (mentioned above as being supported in the new Finder) is a game-changing technology that works to efficiently distribute computing tasks among all available processors. For the last few years, increases in CPU clock speeds have been downplayed compared to increasing the number of cores available on a single chip.

Every Mac now has at least two cores, and some Mac Pros have 16. In the next year or so clock speeds will continue to hang in the 2.2-3.0GHz region, but the standard number of cores should increase to four and Mac Pros may go beyond 16. GCD is a software layer that developers can take advantage of in their applications to help schedule tasks across all these cores. If Snow Leopard can do this better than Windows 7, and developers choose to utilize the technology, then this could open a serious performance gap between the Mac platform and PC’s running the exact same hardware.

opencl_icon20090608OpenCL is another new technology meant to better harness the raw hardware power that is already in your Mac. Today’s video cards or graphics processing units (GPUs) are capable of performing calculations for 3D graphics and modeling at an amazing pace. OpenCL is an attempt to let developers harness that power for use in other applications beyond drawing thousands of polygons on screen with fancy textures. Again, if developers take advantage of OpenCL, then Mac applications may run noticeably faster on Snow Leopard than on the same hardware running Leopard or Windows.

Exchange Support

exchange_icon20090608The third piece of today’s announcement is the inclusion of Exchange support directly in Mac applications like Mail, iCal, and Address Book. Apple licensed the Exchange technology for the iPhone, which helped that device make inroads into corporate IT environments. Now that same technology is being baked into Mac OS X so that Mac users can integrate more easily with their corporate infrastructure.

Setup was demonstrated to be quick and easy using auto-discovery of Exchange services and applications were then immediately aware of your accounts and resources on Exchange. You can continue to drag-and-drop people onto iCal calendars to make appointments and so on. Many people will appreciate that you can blend your personal and business information in one interface by seeing both personal calendars and Exchange calendars or personal contacts in Address Book alongside the Global Address List from Exchange.

In my opinion, the new Exchange support is going to do more for bringing the Mac OS into the workplace than Intel processors, Active Directory integration, virtualization, and the iPhone have accomplished in the last several years.

Pricing & Availability

Snow Leopard will be available in September for $129. Special pricing is available to current Leopard users who can buy the new release for the very modest price of $29 for a single user or $49 for a family pack. If you buy a new Mac with Leopard today, you will be eligible for the Snow Leopard Up-To-Date program, which is only $9.95.

With this sort of pricing, I don’t see any reason not to upgrade to Snow Leopard. I’ll be waiting in line myself.

  1. yep, finder is pathetic. any power user that has to go from the insanely easy multi tasking of windows to using this finder crap knows what were all saying about no cut and paste…the ultra gay fact that new folder is not on the right click menu and then it places the new folder at the root instead of where you just told it to(to buddy whos been using his mac since way back to jack..go eff yerself cause you dont know didley about speed and efficiency), the dock is shite…it takes so many more clicks and steps to acheive the same task that on a windows machine is so easy…..i use both mac and pc and half the time i have to unpack archives for mac on my pc cause mac is just so gay…if you click an icon in the dock to open the window why not be able to click it again to re-close it…why get carple tunnel just because the idiots at apple are so ego based and dont even use their own equipment…i mean a one button mouse??? wtf, how you fools will keep digging yer own grave with that stupid elegance mentality…thank god i can use firefox and not have to suffer with that safari bs… frustrating

  2. As a user of a dozen of OS, I find absolutely ridiculous the absence of cut/paste files! When you pay $2000 a modern computer such a basic function should be present. People who don’t want to use it for religion reasons can follow other methods!

  3. To spare u searching wrong way, thought i had find something to circumvent this, it was quicksilver, since i ve upgraded to SL and QS as well, proxy objects and/or qucksilver are not working any more on these files manipulations

  4. I’ve been using Macs since 1987.

    Moving files around ON a drive, you don’t need cut, you don’t need copy.

    From an open window, select the files you want to move, grab them all in one fell swoop, drag to the main drive icon, and use the spring load function to move them to the new location.

  5. All this c**p re windoes and macs. Fact is that SL is fast and much more productive than any windows machine I have come across.

    So If you don’t like using a mac then don’t. Use a window machine and spend most of your life talking to IT people or repair shops.

  6. I stumble upon that thread because I was searching to cut and paste files in snow leopard. I m using a mac for professional reasons more and more, and that’s true that you can’t cut and paste a file or in simple words move files from your internal to external hard drive. This is incredible, could not believe my eyes !
    How do you do guys/girls when you have to save a selection of files from internal to external HD ? You never have to do this ?
    And I m not speaking about the folders things… drives me mad. I have to get back to my basics with the shell, feeling very comfortable when you have to move files, replacing files on another drive :-(
    To spare u searching wrong way, thought i had find something to circumvent this, it was quicksilver, since i ve upgraded to SL and QS as well, proxy objects and/or qucksilver are not working any more on these files manipulations. And… guys behind QS probably have other work to do or else, and as a matter of fact, full SL compatibility seems not for tomorrow. I have a question for people that are really working on a computer or just sometimes moved divxs between HD : any suggestions quicker and safer than the shell and terminal window?

    Sometimes Apple sucks really hard.


  7. A regular default upgrade of Snow Leopard will automatically reclaim the saved disk space for you. I got an extra 11Gb on my 13″ MacBook, and 10Gb on my 20″ iMac. (both were running 10.5.8)
    I honestly wasn’t really expecting to see the full 6Gb, so I am pleasantly surprised!

    • If you get along well without it, that’s because you are not transferring large folders.

      I’m trying to move (ie cut and paste) a 120GB folder. It should take 1 second to move it.

      The OSX system does not permit it. It only enables in this situation a copy. That takes over one hour!

      “Move”, Apple.

    I’ve been using Macs since 1987.

    Moving files around ON a drive, you don’t need cut, you don’t need copy.

    From an open window, select the files you want to move, grab them all in one fell swoop, drag to the main drive icon, and use the spring load function to move them to the new location.

    Or open the two folders next to each other. Drag and drop is NOT that time consuming. The OS does the move automatically. Just as easy as cut/paste.

    Now moving BETWEEN volumes, you’ve got a point. A move command that would copy, then delete after the move would help. Same basic function as cut, only one less click than cut/paste. There, the Move command from Windows would be great, I use that at work occasionally.

    Point is, it is a subjective preference. You work your way, I work mine. Just like in Windows, there is more than one way to skin that cat.

  9. AzaMcWazza

    So you’ve never had to rearrange files around on a drive? If you have then the only options to you are drag and drop (That will cut/move) but this is less user friendly than a key press, and copy, paste, delete which is way to much work IMO.

    It could be to do with the fact that I am not a “normal” user who does little more than check mail and browse the web. I develop on my mac and use it for photography and other things where I’m dealing with files all the time. I often need to move them. A Cut option would speed up my workflow immensely.

  10. rwahrens

    Ok, I looked again, and you are right. No cut.

    Sorry, I fail to see the ridiculousness of it. I use copy/paste all the time, but not cut. I see no utility at all.

  11. rwahrens

    You CAN copy, cut and paste in the Finder, all you need is to do a right click (or option-click if you don’t use a two button mouse) on the file (or multiple selected files) that you want to cut or copy. The commands are there, on that menu, to allow you to cut, or copy, and paste that file or files to another location.

    It has been available at least since Leopard was introduced, I use it all the time.

  12. pony slaystation


    Totally agree with you there. Finder sucks big time! One of the first things I did when i got a mac was getting pathfinder which does have cut and paste options etc.

  13. Gripdog

    As someone who has been contemplating a new computer, and aware that this upgrade is coming, I appreciate the summary and pricing you provided. They haven’t been able to provide such detail in the retail stores, particularly as it relates to timing and pricing. I was delaying a purchase, but knowing that $10 gets the upgrade, I’m going to move forward.

    Belinda Collins needs to relax and switch to decaf.

    Thanks for the info.

  14. AzaMcWazza


    I had no idea of that command and I’ve been using Macs solely at home for about 2 years. Thanks very much for that tip!

    I also agree with Rob Oakes, merging copied files would be great.

  15. George

    I hear that Snow Leopard will be on the order of 6GB leaner on the hard drive than Leopard. Will the upgrade reclaim that space or will it require a fresh install?

  16. @Galley. Cut and paste in the finder doesn’t work the same as cut and paste of text. Instead, it works to move files rather than simply copying them. This is one feature that should be straight up cloned from Windows. If the power fails mid-way through the transfer, then the unmoved files are still in their original locations. You can then merge the new and old files by re-performing the cut and paste.

    Another enhancement I would like to see is the option to merge two folders of the same name rather than outright replace. Windows does this, and it is tremendously handy. When there is a duplicate file, it notifies you and asks you what you want to do. I know that there are other tools that accomplish the same thing, but having it baked into the OS is a god-send.

  17. Greenbookartist


    Regarding Getinfo, are you aware of the Multiple Item Info window? Just select the files you want, then press “option+command+i”.

    I do agree that cut and paste would be nice in the finder.

  18. Belinda Collins

    Did you tell us anything we didn’t already know, any insight whatsoever other than “I’m really excited by…”

    Rather disappointing, sometimes it feels like this blog is written by teenage boys. Analysis, thoughts and cutting edge news is why I come here, not regurgitation of Official Press Releases…

  19. AzaMcWazza

    Have they fixed all the broken parts of Finder while they were at it?

    Namely, cut and paste of files? I mean come on, where the hell is that feature?

    Being able to select a number of files and do a GetInfo and only have 1 window appear with the size of them and their common information.

    Creating a folder while in list view should create it as a child of the selected folder, not in the root of the hierarchy.

    If you get an error while copying files, the copy window just sits there and you can’t close it.

    There are a massive number of issues with Finder that should have been fixed or implemented years ago. It’s absolutely appalling as a file management interface. While I hate Windows, Explorer annihilates Finder in this regard.

    Snow Leopard won’t be $129. Its just $29 for a single user, $49 for a family pack. If you have bought a recent Mac, the upgrade price is a nominal $10.
