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.

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:


:ch: If you are updating from 10.15.6, 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 10.15.7 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 2 reboots and ~20 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:

2 reboots and around 15 to 20mins install time, working great under opencore 0.6.1

19-minute update. Unusual build number (19H2) this time...
No problems with that update. Everything fine here with OpenCore 6.1. Took indeed less than 20 minutes.

Unprecedented to see a .7 release for macOS/OS X.

Maybe Apple realizes how bad Catalina was as a release. It's much better now, but still bad.
Throughout the version history of macOS, 19H2 is the first time for a build number with only 1 digit after the alphabet.
Very fast update.
