Repair Mac Target Disc Mode
I have a 4 year old iMac which is in a continual loop after an os update. It turns on with an update bar. The bar updates and then goes to a grey screen for a few minutes and then starts again. I have tried recovery mode which I can't access. Internet recovery mode works but after the process, the loop starts again.
I can access the hard drive in target mode on my MacBook air but because it is running Sierra I get the message "You can’t use this version of the application “Disk Utility” with this version of MacOS.
Does anyone have any suggestions on how to fix my iMac?
Thanks.
