"iMac Pro" kernel crash

If you haven't already, boot into the recovery mode (CMD R) and in the menu turn off all secure boot functions and make sure you are on the latest Mojave. it helps a little. (the secure boot stuff is T2). For good measure I disabled Siri as well.

iMac Pro( base model with the 8 core and Vega 56 )

I had a replacement iMac Pro under warranty with similar problem , the first iMac locks up and reboots , and the second IMac crash freezes (only mouse moves). in both cases, this happens mostly during exporting in Final Cut Pro X.

For anyone else who was looking for more info on this topic and owns an iMac pro base model like me:

I was getting kernel panics, mostly while using Premiere/After Effects, also my wifi would sometimes freak out.

Took to apple care, they replaced the logic board, didn't help. After chatting with Apple support they said it was related to the software on the computer not being able to contact a server and freaking out, making it kernel panic and restart.

I have little snitch installed on my computer to monitor internet traffic, I uninstalled it and used the open source software Lulu instead and it completely fixed my problem. The computer has not had a single kernel panic in over a week, it used to have a panic 2-3 times per day while doing video editing.

Hope that helps someone else. I'll be avoiding Little Snitch from now on.

That sounds like rubbish. I have LS and have not had one in OS panick like this. Only on boot up before LS or any apps load. In any case if an OS crashes because you won't let it connect, then I don't want any part of that computer. in your case I see a case of coincidence, or maybe some trigger happy Adobe crap that caused your panic. I have removed all instances of adobe anything from my lanuch daemons and agents and have no issues with adobe connections. that said, Adobe is notorious for being overly invasive with crap running needlessly. Still I'm glad you are having better luck now.

Apple Support told me to turn off the Secure Boot feature, and so far, that seems to have worked. This page About Secure Boot - Apple Support tells you how to do this. You need to check No Security.

Try disabling Filevault. Fixed a similar issue I had. Apple support recommended this...

Yes, still crashing without using any 3rd party devices. I've yet to run a diagnostics. I'll run one soon though and report back once it's done.

Ran the diagnostics on my iMac Pro and the results were: Reference Code ADP000 - No issues found.
