My wife’s iMac is badly misbehaving and her tech support, that would be me, is not making much headway nor did The Apple Store.
2018 iMac 8GB/256GB SSD/A1418
The Mac was running High Sierra.
She would often find it with a frozen screen and on a forced restart it would report there was a problem and it restarted.
I decided it might be the OS so I upgraded to Big Sur.
Very similar issues followed.
Reported this to Apple Care and they had me take it in to local Apple Store.
They wiped it clean, reinstalled Big Sur and kept for several days.
At that point they said it was running fine. All diagnostics showed no hardware issues.
Using Migration Assistant I transferred her files from the external Carbon Copy Cloner copy.
Same problems returned.
I’m now told by Apple to start totally from scratch. They concluded the user was corrupted.
They didn’t want to see the kernel panic report after each restart. I don’t know how to interpret it. Would it give any clues?
Before I invest multiple hours, I’m curious if experts here feel that I’m getting the correct advice and I should proceed to wipe, install Big Sur, set up her user account, and then install applications one by one.
I’d then use her Dropbox and iCloud syncs for most of her files plus drag copy others.
Thanks for in advance for your advice.
