iMac will not boot (even from extrnal drives) after file vault failed?
I currently have an iMac in for repair, which came in after the user turned on file vault but the machine crashed and he turned it off. After this the unit would not boot beyond the apple logo.
I removed the drive and attached it to another mac in order to turn file vault off assuming this would rectify the issue, however it did not.
At this point i connected a USB pen with recovery on it and attempted to boot, I've now tried 3 different recovery disks and an external boot disk none of which work. I've also tried booting the machine with the internal HD & optical drive disconnected.
If you attempt to boot in verbose mode it seems to stall at a different point each time.
I have also tried swapping the ram out to check this was not causing the issue.
Ist dies eine gute Frage?
