Sadly, I have turned off my access to the Apple Developers Beta program after installing macOS 10.15 Catalina a few days ago.
After the install, I rebooted by MacBook Air and it "hard froze" and we were heading out of town so I grabbed a backup MBA running Mojave.
Then, after getting back at my desk a few days later, it took me quite some time to recover from the macOS 10.15 Catalina meltdown.
The good news is that it's up and running again with a mid June time machine backup of Mojave.
The bad news is that I cannot trust Apple these days and have removed my Apple ID from the "beta program" until further notice.
Even more good news is that my systems will not be crashing and freezing up on reboot
Anyway, I don't see any new feature in Catalina that is useful for me personally and I like the Mojave visuals better than the Catalina visuals
