Hello
iMac A2115 2019 with board 820-01236-A,
A few months ago i received this iMac, wont turn on.
It was a BIOS issue, so I reflashed the BIOS with a file found online. I just changed the Serial number section on the file and the iMac worked okay.
It came back and wont boot. This imac has the Fusion Drive (hdd +ssd). I made all the process to erase everything, create the fusion drive and reinstall the OS, but I was only able to install Mojave, with any other OS version (catalina, big sur, monterey) the Imac wont boot into the OS, it showed the "your mac restarted because of a problem" screen.
-I tried to install only on the HDD (not fusion) and same problem. Only worked with Mojave.
-I tried installing with USB drives and also with the online installer. And same Issue.
-I tried SMC and PRAM reset.
-The mac boots in safe mode ok in any OS version
-I would open the iMac and try another file, but the screen is a little cracked and I am afraid of damage it.
Any idea of what could be happening?
Is there a way to update the firmware of the mac without open it?
Thanks!!
