Black screen with cursor after logging out of guest account on High Sierra

Solution 1:

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!)
