Login screen does not return
When login out the login screen does not return. We just get a black screen. The cursor is still active but the keyboard just beeps whatever we do. Have to power off and on again to get back in.
This ocurred after upgrading to High Sierra
We are running a 21.5in iMac with High Sierra 10.13.5
iMac with Retina 5K display, macOS High Sierra (10.13.5)
