I have an iMac 27” 2019 3.7 Ghz 6 core i5 that keeps restarting at odd times
I will leave it on for a few minutes or put it to sleep and at some point it restarts wiping all of the information I was working with. Apple tech has tried several different ways over the last couple of years but it is no use.
Can I get it fixed or refurbished?
iMac 27″, macOS 15.0
