Apple - Black screen with cursor after logging out of guest account on High Sierra
How I solved this issue on Mac OS 10.13 High Sierra:
- Boot into Recovery Mode (Command-R)
- Open Terminal, disable SIP (csrutil disable), restart
- Login to Guest, logout (it should not hang on a black screen now)
- Boot into Recovery Mode (Command-R)
- Open Terminal, enable SIP (csrutil enable), restart
- Login to Guest, logout (it still works!)
