Please post help requests in the Montery Desktop Support Forum section (not in this thread).


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


- Make sure you use the latest versions of the Lilu.kext, AppleALC.kext and WhateverGreen.kext.

Here's the step by step way to update:
:ch:
Backup your current installation using Carbon Copy Cloner or SuperDuper;

:ch:
Update to the latest Clover or OpenCore 0.7.6.
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.

Note: Before you update, make sure your USB ports are properly mapped. I recommend you use this procedure by @ohchang in his post here to do the USB port mapping or the USB ports will not work.

:ch:
Download the Montery 12.1 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 several 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.​



:ch:
Done! So far, another easy update!

I had to change SecureBootModel value from Disabled to the one corresponding to my SMBIOS profile in order to see the update. Once the update started downloading, I changed the value back to Disabled.
I can confirm this behavior. Thanks for reporting this!
