Author:Vera   Date:2011-01-07

Mac OS X 10.6.6 was reportedly "contains developer support for fetching and renewing App Store receipts," which could mean that the 10.6.6 update is scheduled for release in time for the opening of the Mac App Store. Now with the launch of Mac App Store, Mac users can enjoy the latest Mac OS - the Mac OS X 10.6.6.

Mac OS 10.6.6 update

The Mac OS X Server 10.6.6 Update is recommended for all users running Mac OS X Server Snow Leopard and includes general operating system fixes that enhance the stability, compatibility, and security of your Mac. It also includes the Mac App Store, the best way to discover and buy new apps for your Mac. With the Mac App Store, getting the apps you want on your Mac has never been easier.

As for Mac App Store, different people may have different ideas, pros or cons, when it is reported a cracked open for piracy in the day of launch. But for Mac users like me are probably itching to upgrade to 10.6.6 and check it out. Here's what you need to know about the upgrade.

There are three ways to update to Mac OS X Server v10.6.6:
1) Use Software Update
2) Install from a standalone installer
3) Install on a remote server via Server Admin or the softwareupdate command-line utility

Download the Mac OS X 10.6.6 Combo Update

Mac OS X 10.6.6 isn't a big update, so many of you may be able to upgrade by simply running Software Update or downloading the standalone installer from Apple (the first 2 ways :)) without any difficulty. What you should bear in mind is to back up any important data before upgrade. However, there are a few things you'll want to be aware of beforehand:

Graphics - If you're using a NVIDIA 4xx "Fermi" card, you will have to re-run the NVIDIA Update to regain full acceleration. Make sure you have a Mac Pro System Definition installed from MultiBeast, or it will not let you install. We're fixing the tonymacx86 NVIDIA Update version.
Audio - The Combo update will replace your AppleHDA.kext. If you aren't using the ALC889a codec, you will have to reinstall AppleHDA Rollback using MultiBeast. If you're using VoodooHDA, you will not need to make any modifications.
USB - The Combo update will replace your IOUSBFamily,kext. To restore full USB functionality on a non-DSDT or EasyBeast system installs USB Rollback using MultiBeast before reboot. Download MultiBeast.
Sleep enabler kexts are version specific. Remember to delete it before installing the update if you use it.

As tested, there is no need of any other fixes between 10.6.5 and 10.6.6. If you're updating from 10.6.4 to 10.6.6, you may need to run the Audio or USB fixes above. They're quick and easy fixes, though, so you shouldn't have any trouble.

As always, everyone's build is a little different, so your mileage will a little vary. Then you are highly recommended to learn more detailed information on this update before installing at:
