Mac OS X 10.7.3 Update

Today Apple released Mac OS X 10.7.3 the 3rd major update to Mac OS X Lion. To eliminate any potential issues, we generally recommend to update any supported systems using the standalone Combo installer, and not the built-in Software Update.

Be sure to back up any important data, and if possible clone your hard drive before applying the update.  If you have any issues post-update, boot using UniBeast or rBoot.

What we know about 10.7.3 so far...
  • 11.3.0 Darwin kernel
  • Improved AMD, Intel, and NVIDIA graphics drivers.
    • If you use customized or edited graphics kexts, it will be necessary to make the edits again using the new drivers as a base. 
  • The update will replace your AppleHDA.kext. 
    • If you use ALC8xxHDA for onboard audio, you will have to reinstall AppleHDA Rollback using MultiBeast before rebooting. 
    • If you use toleda's new AppleHDA for onboard audio, you will need to reinstall it before rebooting.
    • If you use VoodooHDA, you will not need to make any modifications.
  • If you use Sleepenabler.kext, remove before updating.
