I started the installation process for the Mojave upgrade from High Sierra but I realized I can't upgrade because of some incompatible enterprise software. I would like to cancel it and prevent the installation when it restartsenter image description here

  • Did it format the drive and begin copying over? If not, just force quit it (apple logo on the menu bar; top right of your monitor) – Allan Sep 27 '18 at 13:53
  • It completed the first step of the installation process, if I restart it will finish installing, which is what I would want to prevent to stay on High Sierra. – C L Sep 27 '18 at 14:02
  • I would like to try this - Abort High Sirerra upgrade - but I don't know if it will work for Mojave – C L Sep 27 '18 at 14:04

    Excellent! Give the abort procedure a try and the worst that will happen is you have to restore from backup. – Allan Sep 27 '18 at 14:19
