If the computer is on, hold the power button until it shuts down completely.įind the Command + Option + R keys. Specifically, this was after my computer restarted to install High Sierra, then froze midway, then once I powered off and on again, it became stuck on an endless reboot cycle, where it listed code saying something about ‘Kernel’ and ‘panic’. If you have a Time Capsule Backup this will also work for that. No Time Capsule Backup or USB drive required. I called Apple Support and they shared an easy fix with me. One user commented with this fix which seems to be working for some of the more recent updates causing the rebooting loops: I haven’t had this issue on High Sierra yet, so if this helps, please leave a comment confirming for everyone else. I’ve been told this guide is helpful for both MacOS High Sierra 10.13 and Sierra. Updates for OSX High Sierra – January 2018
