Mac OS X 10.6.3 update targets graphics, security issues

updated 01:10 pm EDT, Mon March 29, 2010

Also supports Logic Pro, Main Stage

After months of development, Apple has released Mac OS X 10.6.3, a major update of Snow Leopard. A central focus of the code is on graphics, as it improves compatibility with OpenGL-based renderers, as well as the reliability and compatibility of QuickTime X. It also fixes color issues in Mail and iMovie, related to backgrounds and HD video, and trouble with "glowing, stuck or dark" pixels when viewing video from an iSight camera on a present-era iMac.

Other areas addressed are said to include printer and USB input reliability, recurring iCal events when synced to an Exchange server, and copying files to a Windows-based file server. Rosetta apps should now properly load files with "#" or "&" in their names, and Bonjour's wake-on-demand function has likewise been smoothed out. Logic Pro 9 and Main Stage 2 have been given better performance in 64-bit mode. A complete list of changes can be found on Apple's support site.

The second major emphasis is on security, as the update fixes dozens of security holes in components including AppKit, CoreAudio, Mail and several web protocols. QuickTime has received the most attention in this regard, with patches closing nine vulnerabilities. The v10.6.3 combo update measures approximately 757MB; smaller downloads, available through Software Update, depend on existing installations.

    Not quite....

    Apple has released Mac OS X 10.6.3, a major update of Snow Leopard.

    How can this be called a 'major' update? Esp. since every other article where it was ever mentioned basically kept using the terms 'minor' and 'not much' and 'small'?

    A complete list of changes can be found on Apple's support site.

    I would doubt that is a 'complete list'. Esp. since several of the items are very generic (unless you think 'improved stability of QuickTime X' means a lot).

    Well, I guess it's a question of journalistic quality (MacNN) vs. semantics (Apple). Both will leave you rather unsatisfied here...

    Wait until...

    I think I'll wait until the reports start to emerge in relation to what the update breaks, denudes and otherwise messes up!

    The "minor/small" change statements you are referencing regarded developer builds. Apple seeds new builds and makes incremental changes to a revision-level release before making the package available en masse.

    And yet, even if you read the change log, there isn't really a major issue in there (which, in theory, is a good thing, one would think).

    Why was 10.6.2 even released if there were"dozens of security holes in components"? That sounds like a major problem. I could see a couple, but dozens!?

    no restart

    After the install, the restart fails. I had to shut down and restart manually. Not a good (re) start for an update
