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
- No native Ivy Bridge CPU Support
- Ivy Bridge Users- BridgeHelper 4.0 Released.
- 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 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.
