Mojave logging me off directly after login succesfully
Today upgraded to Mojave 10.14 from High Sierra
During installation no error messages shown.
Login screen, choose my account provide my password...
My homescreen will be shown... after 5 to 10 seconds I’ll be logged off without any reason. 2nd time login, logged off after 3 seconds, 3rd time logged off directly.
All login attemps did show for a very short time in the left upper corner the green word Profile.
I’ve done a re-installation of Mojave, with the use of command+R during startup. No effect, same behaviour
I’ve used disk-utility, volume check and other checks... all OK
It’s a iMac 5K 27inch, 3TB fusion-drive (year 2015)
How can I stay logged in, without being logged off to the desert directly?
iMac (Retina 5K, 27-inch, Late 2014), macOS Mojave (10.14)
