My 3.3GHz i5 2015 27" iMac has the nasty habit of spontaneously rebooting itself periodically. Looking in Termina at the termination code, it reports "-64" which is "unknown."
I have eliminated the possibility of a bad memory module by removing 1 of the 4 modules in turn to see if the kernel panics continue, and they do.
Although the correlation isn't perfect, I feel that the iMac is more likely to experience the kernel panic during or shortly after a lengthy high processor intensive task. I do use TG Pro to crank up the fan speeds, but that by itself hasn't been enough.
I have a couple of questions...
1. Are there other steps I can take to troubleshoot this, in case I'm wrong about the temps being an issue?
2. Are there other ways to try to keep the temps under control?
3. Is this an issue with ALL 27" iMacs, regardless of year of manufacture, or are modern (say, 2019) models less susceptible to overheating?
Thanks!
