Reliability of the Genius store hardware tests etc.
Any views? Took my 3 month old iMac by appointment into an Apple Store today several phone agents and long calls failed to get my 3 month old iMac restarted. Refused to reinstall OS to what we thought was a clean disk “Running Bless to place boot files failed”. Also Disk utility showed the disk was anything but empty. A large grey bar (636gb ‘other’ and the internal disk allegedly in 4 partitions - 3 not mounted) Agent did a hardware test, much more detailed than the built in one (which btw said everything was fine). No hardware problems. Agent said it was clearly a software problem and would reinstall. Call me later to collect. An hour later another guy rang to say there WAS a problem. The drive was scrap! They are doing it under warranty. The initial problem btw started a week ago with the screen flashing from background to black and back again randomly. The guy who phoned me about the disk told
me the two things were certainly related. I am slightly wary after so many different stories from the phone agents and now the store techies. Left me wondering how reliable was the Apple hardware test and is it likely the flashing is related to the disk failure? Thanks in advance for your comments. 2019 Apple iMac 21.5 with 1tb Fusion Drive,
