My imac keeps reatarted many times after running a half bar under apple symbol. And pops up the small screen “your computer restarted because of problem…..” then restarted and restarted repeatedly with blank screen. Please help.
First try safe mode. While starting up hold the shift key down till you see the Apple logo. It stars slower this way. May be asked for your user password. Safe mode clears cache files and only loads basic system. If you can run safe mode then restart and see if you can boot to screen. If not. Shut down and the restart while holding the command and R keys down till you see the Apple logo. If this does not work start holding the option key till you see your startup disk and the recovery disk. choose the recovery disk.You will get a screen with the options to use Safari, Time Machine, Reinstall and Disk Utilities. Choose disk utilities. In disk utilities go to view and check show all devises. Then click on your drive and at the top middle first aid. Then run it. If it finds problems run it again. Then quit disk utilities and back at the recovery screen run a reinstall. Will not delete any personal files.

I would add one more thing to do besides the link at the top. Go to recovery and run disk utilities to repair drive.
Thank you. I am quite a new user and really bad at imac. Would you please guide in details for the starter like me. Appreciate

Keep my imac repeatedly restarted.
