iMac 27" Boot loop (Everything tried)
Yesterday i went to a friend who have a iMac 27" 2019 running Monterey and Fusion Drive.
He called me because the iMac had began to restart it selv in loops doing the night. I told him to do all kind of things but it didn't help so i went over there and did it all my selv and still didn't work. Then i reset the fusion drive and rsinstalled the OS and it was running good for 2 hours and then i went home.
Today he called me. Same problem again. I have done hardware Diagnostic, Safe Mode etc. etc. etc. I done it all.
Now i suspect memory maybe or PSU because it is really weird.
Any suggestions ? is it possible to test ram by trying one blok at the time ?
Это хороший вопрос?
