Shuts Down Ati Controller On The Report Imac Intel 27 Emc 2390
Chosen Solution My 27in imac is crashing and the report said that the Ati controller is at fault. Does this mean the GPU is failing?Newly format with high Sierra with 12gb RAM Sadly that’s does sound like GPU board (ATI = AMD) I’m suspecting the VRAM has overheated. I would see if cleaning the fans and heat sink fins of the dust and debris as that often is the root issue....
