"iMac Pro" kernel crash

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...!

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 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...!

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 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.

macOS Mojave fixes absolutely nothing regarding this issue. See bellow:

Today another frozen/black screen after a long while without the issue.

I was extracting with The Unarchiver 4.0 a huge (44,9 Gb) splitted .rar archive on an external SSD via Thunder3->adapter->Thunder2.

Suddenly I got frozen mouse and keyboard and, after 1 minute or so, the display turned black.

I had to shutdown the iMac Pro pressing the power button.

Like two months ago, the issue arose when working with large files and external disks.

macOS Mojave 10.14 , randomly crash

{"caused_by":"macos","macos_system_state":"running","bug_type":"210","os_version ":"Bridge OS 3.0 (16P375)"

regularly it happened when connecting Logitech mouse (performance mx) , or external display thunderbolt 3 .

sometimes it happens without doing anything particularly serious not(rendering ,photo video editing) , only watching a movie through a vlc player may cause crash.

I try evrething reset smc , pram

disabel file - vault

turning off all energy - saving options.

turning off all startup protection options

it's really absurd that the such an expensive computer works so unstable.

I really hope that Apple will fixed that

Update: same problem without time machine backup drive attached. I also disabled Power Nap.

I Called Apple Support and they sent me a diagnostics tool that I should run. I uploaded the diagnostics file to Apple. Let's see what they will tell me.

iMac Pro 8 core Radeon Pro Vega 64. I have the same problem. I had contact with the support all year. The diagnostic tool ran several times on my system. Several clean installations of 10.13 and now Mojave didn't help. Support advised me to buy an external graphics card. I am incredibly disappointed.

Yes having exactly same issues - System - iMacPro (2017) MacOS Mojave V 10.14.2, 3Ghz Intel Xeon W Memory 128GB 2666 MHz DDR4, 10 Cores, Radeon Pro Vega 56 8176 MB - purchased mid 2018, with extended Apple care warranty - set me back $15,000 AU.

Since September 2018, I have had many kernel panics and finder crashes, restarted with the strange colours, no bluetooth, no sound available, colour issues - blues were orange and oranges were blue, reported to apple they gave me fixes (reset, reboot in Recovery do first aid, asked me to update to Mojave which I did all - worked for a few days, crash again, had to reinstall from scratch 3 times so far. Tried to disconnect all drives and anything that was not Apple, still problem persisted. I use computer for a Music Production and audio business so some products and plugins are 3rd party by default so cannot get around that one. Took to Apple certified service centre where they ran diagnostics and replaced GPU. Got it home and within 2 days, bingo - restarted by itself finder phrases, kernel panics........ on and on and on.

Read these forums, filevault was already off and turned off power nap.

Hoping it is power nap, fingers crossed as I load up a half finished client project due mid February.

Hope we can all enjoy our beautiful machines that promise to be a working professionals delight.

My next step is open another ticket and demand a fix, new machine or at least some more answers but I take advice from these forums and stick to my guns. After all, $15,000 AU is a lot of money to spend. I have been a Mac user since Apple, IIe and all models since, back in the 80's and early 90's (I have a museum collection of old machines) and have been contemplating getting a specially build DAW PC instead.

Hope I am not carrying a dead bunny.

Best to all,

Wayne

Yep I have 10 Core 128GB RAM Vega 56 run Audio/Midi and crashes kernel panics every day. Too many times have I reinstalled OS. My case has been escalated to High priority by Apple support and it is being "looked at" again tomorrow by Apple service centre. 3rd time I have taken my $15000 computer for a drive. Another week in the studio back to using the old trusty MacBook Pro with 16GB ram Quadcore to get some work done on client projects. At least it is not a T2 baby and does not crash or have kernel panics. Wish I could install 10 Cores and 128GB RAM into it and I would be a happy camper. I have been shopping around for someone to build me a Pro DAW PC - did I just write that? (I have been a Mac Apple fan boy since Apple IIe back in the late 80's).

Hey I get the Finder Crash and kernel panic, restart thing running big Logic Pro X projects. 10 Core iMac Pro 128B RAM Vega 56. Does not matter if I load project in Logic Pro X or Cubase or using VEPRO to host the samples, Logic Pro X runs fine , big Orchestral template, around 86GB RAM and happens when I am using Play by east west and loading Hollywood Strings Diamond. I have spent the last 5 months trying different scenarios, replicating on my 4yr old MacBook Pro - albeit a smaller size template (which does not crash as it does not have T2 the devil baby) I get the "play cannot find sample XXXX please reinstall ....." and then the finder crashes, lose my hard drive icons cannot save anything, have to reboot, and often, have to reinstall OS as the screen is bright orange and no volume and no bluetooth upon restarting. I have tried so many variables, disconnect all peripherals, et al ad nauseam..... (I am an experienced Mac user from the 80's) and it still does this crash, panic, random restart, dodgy dodgy dodgy - Maybe I should have spent the $15000 on a brand new Hyundai car which may have given me less grief? (N.B. I hate Hyundai cars).

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