My 2011 iMac 27" does not boot after randomly restarting.
My iMac 27” has been randomly restarting and kernel panicking for a week, as well as getting hotter.
It boots on an external ssd connected to one of the thunderbolts ports since the internal drive died.
Now, after a final restart, it does not boot anymore : the external drive’s led lights up, the fans rotate the cpu seems to warm up, but no chime and the display remains black. I also checked on the network and with Remote Desktop : nada. I.e. the Mac does not boot.
I’m thinking power supply or graphic card… I did a hardware test last week and there was no problem ;except for the internal HD.
Any insight ?
Thanks
Sergeï
