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

- Make sure you use the latest versions of the Lilu.kext, AppleALC.kext and WhateverGreen.kext. They will be in the latest release of MultiBeast.

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
See the tonymacx86 Clover Builds (in Download menu) to update Clover.

:ch: In February 2020, Apple "clamped down" on non Apple approved kexts. So, update Lilu, WhatEverGreen and AppleALC, placing them in your /EFI/.../Clover/kexts/other/. Remove these kexts from the /Library/Extensions/ folder. See tonymacx86's thread:

https://developer.apple.com/library/archive/technotes/tn2459/_index.html


:ch: If you are updating from 10.15.5, then you don't need to apply any new Port Limit Removal Patches. If you are updating from macOS before Catalina, apply any 10.15.0 Port Limit Removal Patches. Better yet, if you have created a SSDT-USB, then you're all set.

:ch: Download the Catalina 10.15.6 Update in Post #1 or the update from Apple's Mac App Store and run it - the updater will reboot upon completion.
Note: Update will reboot several times; each time Clover picks the correct boot partition. So, sit back and relax. The update takes 25-30 minutes to complete.

You do need to watch that you boot from the correct disk after each restart (The one with 'Install' in the title) as the system seems to default to anything but the right one.


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

Please post help requests in the Catalina Desktop Support Forum section (not in this thread).
Post #1 will be updated as new information becomes available.

Updated my rig to Mac OS 10.15.6, no problems.

1. Went to "About this Mac...", then selected "Software Update." There was an update available, so I selected "Update". It began downloading. After it was finished, it informed me to restart. I hit restart, and the display switched to the Apple logo on black background with the progress bar. This was about 2 min

2. The system restarted, then put me into the OpenCore boot disk selector. The default was "macOS Installer" which I chose. This went into the Apple logo and progress bar. After a little wait, the display switched to my secondary screen, with an "Estimated time remaining..." message. Then it restarted. This lasted ~ 6 min.

3. After the restart, again at the OpenCore boot disk selector, the default was "macOS Installer" and I chose this. Apple logo and progress bar. After 2 min, the display switched screens and the progress bar was about half way, with "About 30 minutes remaining." The time counted down, and there was rapid disk activity. After about 7 minutes, it restarted.

4. Arrived at the OpenCore boot disk selector, and it defaulted to my system drive. Selected this, and it brought up the Apple logo and progress bar. Disk activity. Switched to my secondary monitor. Switched to my primary monitor, then "About 10 minutes remaining..." After about 10 minutes, I ended up at the login screen! All done.
 
Updated from Catalina 10.15.5 right to 10.15.6 without any problems..

My rig was taken through the same steps, it was a different way to update but without any problem.

Well, okay, went ahead and did it. Seems fine. But this release is not where I'm focused......Big Bird, uh Big something like that or other.....that's where I'm focused.
 
Today Apple released macOS 10.15.6 Update, a major software update to macOS Catalina.

Thanks Tony! No trouble here. Updated Lilu and WEG first.
