My fault. Installed Beta 2 of Tahoe over Sequoia.
However, many people have reported success with the installs and I have done these DEV installs with much success over the years.
So, for fun, I did the upgrade on my MacBook Air which is a secondary laptop to my MacBook Pro (which I left on Sequoia).
As soon as installation was done, the OS kept crashing. Not a full reboot, but kept returning to the login screen.
A WindowServer error showed up.
I have about 20 different apps that start up with Mac OS so it could have been any one of those apps that caused the problem.
In any case, I am in the process of erasing my Mac and re-installing Sequoia.
