I started having problems when my Mac would start, seeming the hard drive had eventually corrupted and couldn't get past the start up bar
I have purchased a new drive Sandisk SATA iii 512mb + Heat adapter (OWC) but after checking realised this may not be compatible as the iMac only has SATA II (correct me if i am wrong!), I had cloned the drive with Carbon Copy Cloner from my Macbook pro drive 13" 2011 and even tried booting from a USB OSX High Sierra (Same Issue)
So I regrettably reformatted the original 1tb OEM Drive (lost all prior data) and it mounts and works fine in a caddy on my Macbook, reinstalled as the original drive into the mac and it basically slowly starts the Apple load up process and then goes pale grey and restarts continuously (same issue as before).
Please help!
Does this sound like a graphics card issue?
