"iMac Pro" kernel crash

Have you unchecked and turned off absolutely everything under Energy Saver and then done a cold boot? I'm convinced after breaking out my daisy-chained drives (which stopped the Bad Magic panics) and unchecking all the power settings (which stopped the undocumented reboots) that this was the cause of my problems on my 10-core.

I was replying to Radman, who was saying the plan for their system was to daisy-chain drives, and did anybody have a problem with that.

The best response for others I think just came in from CMAAR above, which supports my comments on energy saver - turn off all this sleep, hibernate and wake-on-brain-fart stuff.

So here's one interesting thing I didn't notice before... I never tell iMac Pro to "Sleep". Today I went into the menu and clicked on "sleep". And it did. For about 30 seconds. Then not touching the machine or anything around it, I got a nasty "beep" and it sprang to life again. I tried it again and it took longer, but it woke back up the same way.

Can you folks put your machine to sleep and have it stay there or is it just me????

Not sure if you have a ticket with Apple support, it if not I would think you would want too. The only thing I can think of is whether or not you installed a new version of MacOS and then reloading all your other items from Time Machine or just reloaded everything from Time machine. The former is probably the better way to go. But even with that, i think you have something else going on. The beeping is concerning.

Like I said like 4 or 5 months ago, panics have pretty much stopped after I turned off all the sleep stuff. But there's still screwy stuff happening on the I/O bus. I have 3 LaCie thunderbolt connected, 2 are TB1 and one is TB3. Watching the lights when I click Sleep, it takes about 20 seconds to quiesce, and then #22 starts to write like crazy, and then all the lights go off and the systems sleeps. For 3 seconds. Then the drives wake up, and #2 starts with the I/O again for a few seconds. But the screens stay dark, and the drives stay lit for 90 seconds, and the whole thing continually repeats. Can't find what's doing this, but it can't be good for the drives.

I still get green artifacts on my second screen. But it's a 2010 Cinema and nobody is supporting that. Funny thing is an Apple update fixed the problem for a month, and a subsequent update broke it again. So engineering is still screwing around with video in the background working on something....

Lastly, I have a box that drives the Displayport for the Cinema Display, a CalDigit USB-C dock. Had to give up on the audio coming through that because something causes long stream disruption in the audio.

So LOTS of I/O bus issues still happening. But at least we're not PANIC dumping every couple of hours like the beginning when I had power saver enabled.

My iMac Pro 10-core has been routinely rebooting itself or freezing ever since I got it. I keep thinking I've isolated the problem (USB-C to DP adapter, or USB hub, or a certain piece of software, etc) but it keeps doing it. Sometimes it'll kernel panic 12 times in a day, other times it'll go for 3-5 days with no problems.

It's absolutely infuriating for such an expensive computer.

So the 10.13.6 install had a progress bar, did what I can only describe as a full shut down, not just a restart. Everything powered down including external drives, sat for almost 30 secs, came back up, progress bar, short restart, progress bar with time remaining. I'm assuming there was a firmware update, but it was not the "fat" progress bar I've seen on older machines and I got no warning about removing power.

Boot ROM is now 15.16.6059.0.0,0, can someone on 10.13.5 check their Boot Rom to see if it did a firmware update?

I've been waiting to buy an iMac Pro since last year. After reading this thread, now I know why I hesitated. I will not spend one more dime on anything Apple until Tim Cook and the boys *** start getting back to some simple core values of customer service, transparency and honesty. Did a slew of engineers leave Apple since Jobs is gone? It's becoming a disgrace; please keep this post alive for all of us waiting on Apple to make a computer again that 'just works'.
I just watched the debacle unfold on the new MacBook Pro i9 throttle-gate. The fact that in 2018 Apple has no cooling system for their products is still a mystery to me. Is liquid cooling not possible on a macbook or imac? Is Apple engineering really this inept? I've avoided Windows like the plague since 2007, hate to think of going back....
thx...

Craig,

Are you bothering to fix the crypto val errors, or just using the machine as is?

I’m trying to decide if this is just a cosmetic error in the disk Utility report or if I should invest the hours to do a wipe, format, and restore.

There are clearly Thunderbolt buffering issues, and for anything that's going to push the rated capacities or buffering or timing at the lower settings (T1, T2) you really have to move away from that. There are issues that they are clearly not talking about. Not your issue, but for example they "very strongly" advised from a "personal perspective" that you should not daisy chain. Only reason they would say that is if there were buffering or queuing problems.

Had a call with my support engineer yesterday, who wanted me to find/remove a kernel extension named com.zerodebug.audiomuxdriver.kext. I did not have the extension on my iMac(at least not in the usual location) and I let spotlight search my machine and did not find it. There is at least one apple support thread that points to this extension causing kernel panics. I believe it is related to PACE copy protection, but Im not certain. Ive long loathed PACE software since the days when they would BSOD my windows computers. I had swore any software off that used this copy protection. I guess Im getting soft in my old age. Anyway, since we couldnt find the file, he was going to reach back out to the engineers and get the next steps.

That said, I am not 100% comfortable with how I see this going down. I may be getting the wrong impression here, but I get the feeling that if I can remove an offending application and stop the kernel panics, apple will consider this "solved". However, if I cannot reconfigure my iMac to the way I want it- (app nap, unlock with apple watch, etc) this is not solved for me. If I cannot daisy chain my UAD apollo to the additional uad2 dsps this machine is useless. I am happy (to a point) to help Apple determine the root cause, but I feel like right now they are only looking for rogue software. There is a variety of different software that seems to be causing this, so I dont really think its the software. Everything points to TB...

If an Apple engineer would like to come spend some time troubleshooting my setup, I will be a gracious host...

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.

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!

Sorry to disappoint you but macOS Mojave fixes absolutely nothing regarding this issue. See bellow a log of the crash that happened yesterday one day after installing Mojave.

Hey,

I did not read every reply, don't be angry if already posted. :)

I have the exact same problems with my iMac Pro with the small graphics. Sometimes, maybe twice a month it crashes while working with Nuendo by Steinberg.

I could figure out that the Philips Hue Sync App triggers this bug type 210. With the software installed and using the synchronization it crashes maybe one time per hour. After deinstalling everything works, let's say "fine".

This bug did happen with 10.13 and 10.14 and the newest Hue Sync Software. I guess it's not compatible with Mojave yet, but I could install it and it did what it should. Well, it crashed the system, too.
