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 Downloads > Kexts area.

Here's the step by step way to update:
:ch:Backup your current installation using Carbon Copy Cloner (see the link above to CaseySJ's script) 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 10.15.3, 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 10.15.4 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:

Installed fine one reboot with OC, automatically continued install after reboot. Did notice a bunch of garbled text on the screen instead of a progress bar and Apple logo. This might be due to the older version of OC that I am using.

Update:
HDMI audio seems to be causing kernel panics for me when waking from sleep. I will disable WhateverGreen for now.

one of my simplest updates for a long time - I suspect that whole time I went through contortions to not just put all my kexts in /CLOVER/kexts/Other it was indeed as pointless as I worried it was

anyway I'm probably seeing things but I can swear... teh snappy ...

<opens Music.rapp>

aww, I'm kidding Music.app. But I've done a decade thinking "the next update will sort iTunes' performance"... so forgive my skepticism

Thanks Tony, I had a smooth update here. I updated Clover and kexts first.
