iMac Pro is crashing all the time. I have reset pram, clean install of Big Sur and all the hard drive sleep settings and key combination resets. This thing was crashing during sleep, now it is doing it while I am working. I left Windows for the stability of macOS did Bill pop in and start managing your engineering department?

Anyone have a fix for this?

If that may help, some threads resolving similar problems:

I had the same issue after upgrading to Big Sur. Computer would crash every five minutes with no applications running (just sitting idle).
Apple walked me through the following steps.
Boot into Safe Mode and see if computer crashes (it did eventually)
Create a new user account and see if the computer crashes (it did)
These didn't solve my problem, but may be helpful for others. Eventually, I needed to boot into Internet Recover mode (Shift-Command-R), erase hard drive, reformat hard drive, and re-install Big Sur. Once I did that, the problem was resolved. A radical solution, but it worked. Apple was very helpful in resolving this problem. On the positive side, a new install was a nice refresh and my laptop runs faster. Luckily, I had all my data files in my Apple iCloud Drive.

And that is a long and widespread problem, dating back to Catalina.
They say here it's GPU related.

Been having the same crash as everyone. I noticed a pattern, The crash seems to happen at Idle times, and a few times I noticed the mouse froze when coming back to the mac moving the mouse around seems to unfreeze the mac. I ordered a "VAYDEER Tiny Mouse Jiggler USB" which causes your cursor to constantly move when you have it on (Assuming any juggler that has the cursors moving constantly will work). Every time I leave the Mac I turn it the "Mouse Jiggler" and for the last week I have not had a Kernel Panic, normally had them a few times a day. Not sure what this proves but I think something on the Mac tries to go to sleep when it is Idle it crashes. If anyone else has a mouse jiggle can you try this and see if it make a difference?? 71taVuV94WL._AC_SL1500_.jpg
