I installed Catalina 10.15.2 only a couple of days ago. For that reason I ran the system updater, instead of the combo updater as I usually do. To my surprise, there was no second reboot, although the process took nearly 45 minutes. When it ended, I had 10.15.3. I rebooted to be sure, and the install drive was not there. So far, everything "just works." (Clover)

Installed 10.15.3 after moving all "unsigned" Hackintosh kexts to EFI/Clover. I had to mind the store and assure that Clover chose the correct install volume after each reboot (totaled two for me), and everything was done in about 20 minutes. Everything works fine.

(PS - I'm actually really happy to see that we should NOW be able to all agree WHERE to place hackintosh kexts, and that debate should now be put to bed!)

check that you have enough disk space before you start (macOS Catalina requires not less than 16GB)
if you are running out of disk space, the update process seems to be OK, but it will go back to the old version
Thanks, that was it!

It's really weird that it doesn't prevent starting the installation process when you have too little free space TBH...

You'll need to use "Clover Configurator" to mount the EFI folder, then copy the extra kexts from /Library/Extensions/ to EFI/.../Clover/kexts/Other/. Then delete the old kexts from /Library/Extensions/, and rebuild the MacOS Cache using the code mentioned.

You may want to have a quick read on Clover Configurator first, before attempting the upgrade. Good luck! :)
EFI Mounter and Hackintool are also options for mounting the EFI partition.

Is Apple "Mail" the only Programm in /Applications, which got updated?

I had to choose manually 3 times the "macOS-Install..." Partition, every time it automatically would have booted from "Macintosh SSD". Bootloader Clover 5103.

:ch: Starting in February 2020, Apple will "clamp down" on non Apple approved kexts.
@Stork just out of curiosity: do you have any sources for this information?
