Mac OS X 10.7.4 Update

Today Apple released Mac OS X 10.7.4 the fourth 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 10.7.4 so far...

  • 11.4.0 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. 
    • If you use Combo OpenCL Enabler, reapply it before reboot
  • 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 AppleHDA for onboard audio, you will have to reinstall the Patched AppleHDA using MultiBeast before rebooting. 
    • If you use VoodooHDA, you will not need to make any modifications.
  • If you use Sleepenabler.kext, remove before updating.
  • If you use SpeedStepper for UEFI motherboards, do not update yet- there is a new speedstepper script coming soon. 
    • Install patched AppleIntelCPUPowerManagement.kext for 10.7.4 from MultiBeast before reboot.
