Pre Update Notes
- This update may break some of your Monterey functions. Make sure you backup first. :thumbup:

Note: Before you update, make sure your USB ports are properly mapped. I recommend you use this procedure:

Here's the step by step way to update OC:
- Make sure you use the latest versions of the Lilu.kext, AppleALC.kext and WhateverGreen.kext.

Backup your current installation using Carbon Copy Cloner or SuperDuper;

Update to the latest Clover or OpenCore 0.7.9.
See the tonymacx86 Clover Builds (in Download menu) to update Clover. To update your OpenCore, see this guide. To convert from Clover to Open Core, see this guide.
:ch: Download OCAuxiliaryTools (OCAT):
:ch: Follow the OCAT Guide:
:ch: After completing the Update, reboot.
:ch: Upon reaching the Desktop, open the Terminal and execute:
nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:opencore-version
Confirm you have updated OC to 079.

Download the Monterey 12.3 Update from Apple's Mac App Store using System Preferences > Software Update, and run it - the updater will reboot upon completion.
Note: Update will reboot three times; each time Clover/OpenCore picks the correct boot partition. So, sit back and relax. The update takes 3 reboots and ~30 minutes to complete.​

Done! So far, another easy update!
