Thank you for the Catalina update! (Still haven't updated because it sounds like a major ordeal)

Ran the update, 16:30 minutes and 2-4 reboots, depending on how you count them.

1. Click install - reboots
2. Boot Mac OS Install from [Your Hard Drive's Name]
3. Boot Mac OS Install from [Your Hard Drive's Name]
4. Boot into [Your Hard Drive's Name]

Well my machine crashed during reboot, just froze with progress bar. Forced reboot and ran the updates manually, the others were ok except for SuppUpdate which I got the error not compatible with this version of OS X. I rebooted into the installer start up in Clover and it installed everything except for the Epson driver which I had already installed manually lol.

Standalone installer for the 2021-005 Catalina Security update is available if you don't want to use the System Updater from System Preferences:

Just updated my old AMD system, worked as expected without any need to update any kexts, patches or settings.

Updated my Mac-Server2 system, old HP Microserver Gen8 which runs headless normally. Three reboots, and took about half an hour to complete the update.
