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

Note: Before you update:
- Clover users must first disable or remove BlueToolFixup.kext in order to update. Otherwise the software update doesn't initialize it crashes System 'Settings'.
- 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 0.9.3 or newer.
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 0.9.3 or newer.

Download the Ventura 13.5.2. 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 two times; each time Clover/OpenCore picks the correct boot partition. So, sit back and relax.​

Done! So far, another easy update!

20-minute update of macOS 13.5.2 (22G91) for my Z370 build with OpenCore 0.9.4

No problems with this update. Using OpenCore 0.9.4 and latest kexts.

I was hoping for macOS 13.6, as the release candidate was posted last week, but I'll take it. This time the update was very fast, well under fifteen minutes.

No problems with OC 0.9.4. for my Z690 build
No problems here. I'm sure I'm getting lazy since things have gotten so smooth. OC 0.9.4, latest kexts. Installed from the previous dot version, on both desktop and laptop. (Both Dell Inspiron family).
3 restarts and 10 minutes later and I am back to the Finder.
OC 0.9.4 and latest Kexts.

Opencore 0.9.4, update Lilu, WEG and AppleALC and forget to count the number of reboots. About 25 minutes to update. Everything is fine.
