Ever since I upgraded one of our schools student MacBook Airs to Mojave, logging out of the Guest User account is broken. The cursor remains over a blank, black screen and nothing ever happens from there. To get it back I need to force a shut down by holding down the power button. I tried booting into Safe mode to see if that would help. It does not.

Disabling SIP with 'csrutil disable' solved the problem for me, although that doesn't reflect well on Apple or MacOS.
