"iMac Pro" kernel crash

After several days of no issues, a few minutes ago I got a "computer restarted because of a problem" message out of the blue. I simply turned on the Mac and got the message followed by the usual "send to Apple" dialog:

{"caused_by":"macos","macos_system_state":"running","bug_type":"210","os_version ":"Bridge OS 2.3.2 (15P6059)","timestamp":"2018-08-12 15:54:42.72 +0000","incident_id":"F324FAC8-004C-47C5-99D6-C81B7DB4B873"}

Very bad.

You KNOW it’s really bad... like an unmaintained library that people have used and is incompatible... that’s why they’re telling everyone to pull different apps off their system like CrashPlan. That is, once you shut off all power management and completely redo your Thunderbolt channels...!

Happen'd three times to my MBP13".

Two times during watching a HD-Movie from the iTunes-Store in iTunes. Both times running on battery.

The picture froze, then goes to black and the computer dosen't responded to anything more, except forcing a reboot. Both times in the last 2 days. No external devices or adapters attached.

The third time during typing this comment: the screen went almost completely black, except half an inch at the top, and nothing reacts. So I have to force a restart - no Crash-Report this time.

Usually I work for hours running the Pioneer Rekordbox DJ-App with an external Samsung T5 SSD, Apple MagicKey & MagicPad, multiple (min. 3) DJ-Controllers, with multiple soundcards, some on an USB-C multihub and even an Acer USB-C-Powered Monitor. No issues then :-O

Also Adobe Lightroom with an external LaCie D2 with Thunderbolt3; also no issues.

I have also a 2017 MBP15" who has problems with the internal speakers. :-(

I bought the 2017 MBP after my 2011 MBP's-GPU died from the known graphics-problem - also happend to a friends 2012 MBP :-((

Hi,

I'm experiencing similar, here is my scenario:

MacBook Pro 2018 15inch TouchBar 2.6 core i7, 16gb ram, 500gb Flash, Radeon 560x.

Running in docked capacity powered in one port and rendering two 1080p displays via thunderbolt 3.0: 2 display port adapter in another, and also magic keyboard/mouse paired... This is +/- 10 hours a day M-F. Other times using machine just as is with nothing attached. Turn off and discharge battery occasionally but I bought this computer to work so I am not going to baby a 3k machine outside of a case, AppleCare, and appreciation. No problems until today.

This problem started today just after I set some sleep preferences since having the machine for going on 3 weeks. I am turning back off "put hard disk to sleep when possible" because this is the most impactful change (I believe) I made. To my ignorance I really need to understand those benefits, and lack thereof, anyway. It just sounded like a healthy option but may have triggered this so immediately not worth it, whatever it is. I'm glad my data and work is stored/managed the way it is or this might've caused a large impact. Will try to report back.

(PS- I wish the 15 inch could be purchased without the Touch Bar! Though I do appreciate the biometric reader...there is a balance for enterprise users, Apple! )

I have this issue. I contacted Apple support about a month ago. Kernel panic every time I was exporting 4k video. It was a repeatable issue. Apple had me create a new volume and install a new copy of MacOS. Still occurred. Took it into Apple Store for Genius to assess. They said it was a memory issue and replaced the memory. I am exporting 4k video for the 1st time since I've had the memory replaced....and crash! If it continues to happen I'll open up another ticket I guess.

Things like environmental setting, KEXTs, and TB peripherals may exacerbate the issue but I guarantee that in the end there’s a platform (MacOS + Mac) issue.

I got mine in December and it KP’d running in safe mode while doing nothing with no peripherals attached in a room at no more than 19C. So did it’s two replacements.

My advice to anyone experiencing this issue is to sit and wait for Apple to fix it but I’m not going to waste anymore of my time trying to troubleshoot it, already did that three times and we’re still here.

I agree about an underlying cause and that we shouldn't waste our time with it. If you can live with it, then do so. Otherwise you need to return it and move on. Apple is admitting nothing, and we've probably got several hardware issues going on and they're not going to declare "oops, everybody bring your unit back and we'll swap it out...". I'm one of the few that has no more KPs... but my system never sleeps and in fact the external drives turn on every 90 seconds no matter what I do. So I choose to live with it and keep the system away from where I sleep...!

Same situation with me. I am stuck with this iMac pro. The problem was reported on the second day of my purchase. Apple support took months and I have exceeded the return time frame. Now Apple totally stoped communicating on support. There is no solution for me now rather keep a $10k desktop at home and make a big joke at my work place. Every 90 second - 2 min all the hard drive will make noice and wake up and sleep. Looks like antique pice of deskto with machinical generator running the outdoor studio.

This *****. All the time new problems. For the first time after taking delivery of this months ago, my Logitech mouse was the subject of a new problem. Suddenly with no warning, it stopped functioning and the red LED just started to pulse every second, sitting down on the mouse pad and not being touched. When you moved the mouse, it would move the cursor an inch or so and stop. Rebooted and of course everything is back to normal. What next? Flashing screens?

Same here always when resuming from sleep, it just goes black and crashes. Well I'll just to go the apple store and complain, they'll replace it with a new one. Apple can eat the cost that happens with this even though it feels like a software bug...

Apple finally agreed to replace my iMac Pro after it kept blacking out after login. I had already had the motherboard replaced once and it worked fine for over a month before the problems returned. I hope this new machine works better but based on other reports, it might keep crashing. Let’s hope the new OS 10.14 update fixes this problem. My gut is telling me it’s a T2 chip issue.

Same story for me but I had my motherboard replace twice and then got a new machine; still crashes; kernel panic; everyone thinks it is the embedded T2 chip; but Apple Support will not own this; just this support group; and numerous websites that cater to Apple owners. I just greatly disheartened that Apple has not come out and said: "We have a problem and we are working diligently to fix and will replace your machine or provide a new OS that will fix this. Just hang in there. We got this. We are on this." My customer support at Apple went to highest level and she was wonderful. Wonderful. But keep telling me that know one is admitting or telling her this was recognized problem. Wow. Sales and product reputation over being honest when a well known problem is present. I am guessing the new OS well fix???? What does everyone else think? Also I cannot keep my computer from going to sleep and when it does it crashes.

I think Apple has this blocked at a lower level to save people’s careers who pushed the design. I’m certain the issue is fully understood but would require a substantial redesign of costly components, which would take a massive effort, huge costs and would still be a “best guess”. So without senior management owning the issue, the lower management will do its best to bury the negative press. Replacing systems and motherboards is a complete waste of time. If you cannot live with what you have today, get a refund and move on. If you want to keep trying, you must reconfigure and fully reload your system until you find a combination that works well enough. Be prepared to replace both peripherals and associated software. This is what I did and eliminated panics and reboots, but have a system which can’t sleep and hits the remaining external storage every 90 seconds doing something I cannot find. Good luck!

I purchased a new iMac Pro 8 core in April 2018. I've had continual major issues with it since day one. Kernel panics, lost data, corrupted ArchiCad 21 and 22 project files. It's losing settings for email and also has issues that are unrelated to ArchiCad. I had it in service with Apple Support and they did not diagnose nor fix the problems correctly. Calculations that should be a breeze for this computer bog it down (in Adobe Illustrator and other software too).

I'm putting it back in my Apple Support service center this week. I've had Apple computers since 1983 and am an advanced user. So far this is the worst experience I've ever had with an Apple product. According to Apple certified techs, who don't work for Apple but work for independent repair shops, iMac Pros are having major issues and Apple does not yet have the diagnostic tools to repair them, plus the techs are not receiving training in how to repair them.

I hate to say it... but I cannot recommend purchasing an iMac Pro. High Sierra may also be part of the problem, but there is no excuse for releasing a product that is this expensive without having repair protocols in place.

I was complaining that FCP X crashes the iMac Pro when exporting 4K video. I was very familiar with FCP but I wanted to see if switching to another video editing software would get the same result. So I switched to Adobe Premiere Pro. Sure, I had to learn how to use it, but I was shocked to see that it doesn't crash the iMac Pro at all. I am now an Adobe customer. One of the downsides is that it takes more time to export a video. I have a feeling that Premiere Pro doesn't use Metal. This leads me to think it has something to do with Metal, in my case. I know FCP was optimized to take advantage of Metal and the new hardware in the iMac Pro. So there is hope for people who do video editing.
