May I add one point to the general satisfaction with Mojave in this thread.
Although nothing either in hard- or in software is perfect, I am a big fan of Disk Warrior.
It just helped me an hour ago to rebuild a Mojave not willing to boot.
The problem is it only works with HFS+ volumes.
Mojave is the last OSX allowing with some turn-arounds to run in HFS+.
I know
the problem with Apple updates but there is even a way to install a small utility warning when updates come.
In any case I followed the suggestion a year ago of a wise member in this forum (Fishrrman) to keep a
Mojave volume in a separate drive in APFS as he called it „a mule“ should I need an Apple update only possible in APFS.
So, at least for me, my MP End 2013 will remain in Mojave
and.certainly not enter the muddy waters of Catalina!
