iMac Retina 5K 2017 experiences kernel panics. Etrecheck report attached.

This system has experienced kernel panics. This could be a sign of hardware failure.


I have tried everything (I think).


Reset PRAM, NVRAM

Fresh install of Mac OS

No apps running


Removed Ram chips one at a time.


Ran diagnostics. No problems found.

Apple Diagnostics does little more than check for the presence of operable hardware. As MrHoffman wrote AD is ill-suited for anything else.


Try Safe Mode: Start up your Mac in safe mode - Apple Support. However, since Safe Mode disables hardware graphics acceleration even it may be inconclusive.


It is nearly certain the Radeon Pro GPU is the culprit here. They can be replaced, although I don't know if Apple can do that any more on your "vintage" iMac.
