OS X 10.6.3 Update Brings Record Number of Fixes


Snow LeopardAs predicted, an update to Apple’s (s aapl) Snow Leopard and Leopard operating systems, which fixes a record number of vulnerabilities, is now available.

The sizable patch, which weighs in at over 700MB, tends to a number of known security problems within the latest client and server versions of OS X, and is the largest update Apple has ever put out. This new update, known officially as ‘Security Update 2010-002’, fixes 92 problems in total, bringing Snow Leopard up to version number 10.6.3.

For those still running Leopard, and and plenty of you are, this update offers 18 specific fixes for Apple’s older OS. Snow Leopard sees 29 distinct fixes, with the remaining 45 improvements being applicable to both operating systems.

Fixes found within the update include improving the reliability of Airport connections, minor adjustments to OS X’s Mail application, refinements to Time Machine’s backup process and more. One of the most noticeable inclusions within this update were the nine critical updates targeting QuickTime. However, the numerous updates to Apple’s media player, as pointed out by Computerworld, come as little surprise due to the impending launch of the iPad. It’s increasingly common for Apple to update both QuickTime and its iTunes software ahead of the launch of a new device.

More information regarding the update, including a full run down of improvements, can be found within Apple’s official support pages. The update can be downloaded now either online or via OS X’s integrated system updater.

Let us know if you run into any issues with this upgrade.

When I upgraded from 10.6.2 to 10.6.3, my iMac would not boot (the Apple icon switched to the Ø icon). It booted (omission of some menu bar buttons; spotlight inoperative, etc.) with holding down the shift key. Running Diskwarrior identified many errors which were repaired (report below), but no change in success in booting machine. A second running of DW showed only 1 error (not reported), but no change in booting behavior.

Since the BIG update I cannot use my VPN, there are 4 pages of permissions when checked – all related with the Airport Utility upgrade.
I can no longer access one of my iDiscs – other is still OK.

Never had probs before – anyone else going loco?

iMac – Very recent model – lots of memory and HD

The last year or so, after updating Mac OSX, I run Monolingual. I have found a large part of the updates are language files. I delete all but English and save a ton of space afterward each time. Which means if Apple would post these updates in single languages, the updates would be about 1/5 of the size. I haven’t downloaded this one yet but the past one was about 700 mb. When I ran Monolingual it said it saved me 600 mb. Yes, I had already run Monolingual before updating.


The Mac OS X Server v10.6.3 Update is different from Security Update 2010-002. The former (719MB for client, 897MB for server), is for Snow Leopard and bring both general OS fixes and security fixes, while the latter (78MB for client, 361MB for server) is for Leopard and are only security patches.


Since the upgrade, Mail refuse to display images attached to emails. So, for example, when I get a promo email from the iTunes store, it’s full of blank space : no album cover is displayed.

Yeah, I’ve run into an issue: My keychain file got corrupted somehow, so I called apple and we got the issue resolved
that must’ve been the wierdest problem I have ever had happen to our computer


700 mb, lets see that is 7/10 of a gig. I remember reading years ago that in the 1880’s that saddle bags, 8 x 11 inches, all 2 of them could hold almost all of the information in the world. Ergo, the Pony Express could deliver it from coast to coast in 7 days. An improvement over todays snail mail. But I diverge: Can’t those genius programmers use Ajax or some non-obese language to deliver these updates. Nowonder hard drive space is in the petra-bytes by now!
