"iMac Pro" kernel crash

?? This issue has existed since the hardware was released -- ~7 months. That is more than enough time and sampling to solve this issue. 6 more months makes my "brand new iMac Pro" 13 months old, before it's working correctly... and that's assuming that they even solve this issue by then.

I just had an email from my certified repair guy that is in talks with Apple. He asked me to send him a system info document to send to Apple. Sounds like they are still working on it and narrowing things down.

I had my call last night with a support rep. He basically gathered info about when it was happening, what peripherals I have connected, and wanted pictures as well. Then he wanted me to run a sudo sysdiagnose within a minute of the kernel panic. I was able to generate everything for him, so hopefully they can get what they need.

Chiming in to add to the chorus of people who have this problem. My iMac Pro is constantly shutting itself off, multiple times a day. Once while reading this thread, after having just rebooted from a previous crash.

I have not called support yet, but the messages here don't give me much hope.

Of the items you mentioned, the only one I have is Adobe Creative Suite but I don't use it that often. Whatever is going on is iMac Pro related because all my software and hardware works fine on my old iMac 2011. I notice my iMac Pro issues when I'm working in FCPX and Compressor.

I’m not sure yet. I have been consistently crashing every night. Since I’m dropping CrashPlan, and incidentally, the main application seems to be crashing lately when trying to launch it (even though it’s kext is running and backing up), I decided to uninstall this one first and leave it a few days, before trying the next two items in the list.

So far, no crash last night with CrashPlan uninstalled. Will see how it looks this afternoon when I get back to the computer.

Just keeping a pulse... still no word from Apple Engineering/Corporate(!). The crashes/reboots have been occurring more frequently, though I’ve been forcing myself to use the device more; rather than relying on my old MacBook Pro when I wanted reliability. I cannot stress that software is irrelevant to this issue... it occurs with a fresh OS/standard apps and usage — not to suggest that taxing apps/usage doesn’t make the matter more prevalent. If anyone has any further updates to share, please post them. Thanks.

I've been in talks with them the past week. Giving them more information about my machine but I haven't had any kernel panics in over a week. It's kinda odd I was having 3-9 crashes a day and now nothing for a while. If something does happen, I'm told to make note of the exact time it happened and then send my contact the crash report.

Looks like it is a bigger culteral issue at Apple. Releasing hardware and software with known issues is not the Apple way. The article was actually nicer than it should have been. But even more interesting was another article on the same page talking about the issues with the new mac book pro, and how Apple didn’t redesign the chassis to take advantage of the i9 chip which has to be throttled back (I assume because of heat) to the point it performs worse than the i7. This would not have happened under Steve Jobs watch.

I agree, I think quality has been lackadaisical for the last couple/few years. And I concur, the article was nicer than I believe Apple deserves, but I am extremely biased at this point. Moreover, until more knowledge is shared, it could be irresponsible to take a different approach. Hopefully this will spark other journalists, or even some heads at Apple, to look into the matter with more detail and fervor. I suggest that we share this article, and continue to press the matter for more/better attention.

While its true that this is frustrating, and I'm the first being annoyed after spending so much on a computer... In the end its still the computer with the least number of issues I have, doesn't make it right, but the Windows & Linux machines I have are much more trouble than the iMac Pro / macOS.

If you need a fast and silent workstation with a great screen, its still the best you can buy. The iMac Pro has no throttling issue I could detect, whether its playing games, or coding... I dont do video processing, etc... so it might be different if you do that, but in my experience running games is by far "the worst case scenario" since it taxes the GPU & CPU...

Agreed. I’m not sure why I did this, but I just bought an i9 MacBook Pro. So now I have 2 T2 based macs. I noticed it was constantly running the fan(especially running VMware fusion/Windows 10, but that was common on my 2014 mbp as well.) I did feel a bit underwhelmed by the supposed 70% performance increase and it felt about the same as my 2014 with a 2.53ghz. I was going to give it another week and the return it if there wasn’t a fix issued.

I get the crypto Val error when running a disk check which did not make me very happy. Who is loading these machines? I buy a Mac because I don’t want to jack with installing and tweaking the OS.

Anyway I installed the i9 fix yesterday and am happy to report that things are significantly better. No fan constantly running and was able to get repeatable solid performance numbers in Geekbench 4. Repeat runs were in a few percentage points of each other and didn’t point to any throttling problems. I’m not in front of it right now but from memory single core performance was 53-5400 range and multi core was 22600 or so. Compute benchmark was not as great but still pretty good with ~22k for the intel graphics and 52k for the AMD graphics. On the open cl benchmark.

That performance is good enough that if I don’t see any improvement soon on the kernel panics I’m returning the iMac. I’m giving it another few weeks.

I’ve thus far decided to ignore the errors. I don’t have time to do the reinstall, and I have a bunch of challenge response software with limited installation counts. I’m really hoping that a software fix is in the works for this. I do think that at the very least it shows a level of sloppiness that is a new post jobs era. I write code for a living, I know software is hard. But come on Apple you have to be insanely great, not slightly above average or quirky.

Does someone smarter than me know what a crypto val error even is? It would be nice to know if it’s just harmless text in the report. Disk Utility does end up saying the disk is OK, despite these errors.

As you stated, a wipe and restore is not a short process, particularly on a 2-4TB drive.

Completely agree that they know all about the problems and that this is a red flag issue in Apple Engineering. Like I said, this was the first time I finally broke through the Engineering blockade and spoke with an actual engineer, usually you are given several levels of interference.

Unfortunately, we're not going to know if they will fix the problem. If they sold 100K units and only 50 of us are having problems, they're not going to declare a chip / hardware failure and do a full replacement... but if we keep this thread alive, we can perhaps find out when they start delivering units that are working and get replacements then.
