iMac Pro restarting because of a problem?

iMac Pro intially booted as a Mac Pro backup, then reverted and reinstalled fresh High Sierra because of some compatibility issues, now getting forced restarts with this error code, thank you for any help!

Indeed, I do, newmediagroup.

HappyPappy, if your iMac Pro restarts with only the OS installed, in what kind of situation does that happen? using safari? Leaving the machine running until it happens? Word Processing? In my case it only happens when I use Compressor. And it also happened once while using resolve (but then never again)

May 27, 2018 9:10 AM in response to newmediagroup

Well John,

The good news is (if I can call it good news) that for now I can do something really specific and get a restart 100 procent of that time. So it's consistent, for now... I will discuss this with apple care and demonstrate it. The guy did say that if it is user related (which it is not) or content related (which in my case it seems to be) then there is very little he can do. However, if Compressor is able to handle these troubled movs on an inferior Mac, then t would mean there's nothing wrong with the files and the SHOULD investigate.

I will try to compress the files on a 2015 iMac and see what happens. I bet they will compress just fine.

PS, I did the Diagnostic thing. Everything's cool

May 27, 2018 9:09 PM in response to INvisibleART

Happens with absolutely nothing running other than whatever Mac OS starts out of the box, brand new with no apps installed and nothing on the screen. Not even linked to my iCloud account as AppleCare stated the problem might be content related (if that were truly true then it would make these new Macs worse than useless).

Problem appears related to sleep/wake (happens on one of those two events) cycle, not sure which.

Oddly enough if I leave iTunes up and running it "appears" to occur less (anecdotal).

On two occasions the AppleCare guys said it's hardware, then replaced the iMac and then washed their hands of it (closed the ticket) even when I said the problem was still occurring (told me to contact AppleCare and restart the process). Honestly they're just padding their stats (closing tickets as fast as possible) and not really concerned with solving the root problem.

Really not happy with Apple on this one, not sure how to escalate this however, if anyone knows anyone let me know, there's a letter to be sent their way.

P.S. running build 17E202, problem still occurs...

Wow, that's a very frustrating experience! I never but my Mac to sleep, it's just the display that turns off after a while. Let me see if I can reproduce the problem on my system. I'll leave it on and uncheck "prevent the computer from falling asleep..."

May 28, 2018 12:48 AM in response to INvisibleART

Well, for now I haven't been able to reproduce this on the fly, but I left my computer on last night and this morning it had definitely rebooted. It was doing nothing at all, I had just left it on. That's not supposed to happen, right?

Also, if my display turns off to save power, after a short while my external hard drive (G-Speed Shuttle TB3) recycles, and again, and again with short breaks in between.

May 28, 2018 5:11 AM in response to INvisibleART

Ok everybody, I escalated this to engineering. I have a job that reproduces the problem every time. It is not content related because the restart or the freezing doesn't happen on a late 2014 iMac with the same os and apps installed and the same job performed. I can even reproduce it on a clean installation of the iMac Pro with only compressor and final cut pro x installed.

So now I'll have to wait until engineering contacts me. The Senior Apple Care guy told me he was very intrigued by this. Let's see how far I can crawl down this rabbit hole.

Keep you posted...

May 28, 2018 8:05 AM in response to newmediagroup

Oh the pressure! They haven't contacted me yet, but they most likely will and start investigating crash logs and all that. By Friday noon I will have received a call. We'll see what and when the postman delivers.

That's a lot of tech you got there, John. My setup is a lot more modest, but I am one of the very few in Belgium who edits episodal drama on FCPX. And I only need two screens, a (stable!) computer and a whole lot of fast storage.

It's really by accident that I found files and a related job that can reproduce the problems we are facing. DV-pal is something I haven't used for over a decade.

Regardless of the fact that this powerful machine may have been build to work with the latest technology, it should not freeze up and restart once you feed it a bunch of old, perfectly healthy files. Something's up, and I'm very excited to know what it is. Because the weird fact remains that the senior apple care guy could not find a single similar problem regarding the iMac Pro. Not in these parts anyway...

All the best,

Steven

Hey Steven and John, I thought my setup was dandy, home office with 5 iMacs, two Mac Minis with VMWare, went with new iMac Pro on the advice of my sales rep and while it works it works great but so far any task I leave running at night tends to end up with a restart by or in the morning.

Steven, if you need kernel traces or dump files, I've been keeping all (most) of mine since December.

Good Luck/Cheers,

Martin/Happy

Just had my first restart on my 4 day old iMac PRO 8 core version, went to google and found this tread,

im very disappointed and don’t know what to do now with this iMac , I thought I’m buying such expensive machine for a long time.

Buy the way it restated in the middle of the day doing nothing.

I covered the whole thread, here maybe 10-15 people complaining , I believe apple sold a lot iMac's Pro but only one thread with 10-15 users that experince the problem and I noticed its from Feb

All this is weird, but there is a gib but, I see people here got replace 3 times their Macs , probably different batches and every time same issue.

So logically the problem in all iMacs Pro, but then again , where all the complaining customers ?

I just finished with apple diagnostics and there is no issues in my iMac , so it looks like a software issue (I hope).

Well, presuming that everyone's using the exact same MacOS software and build (as far as I know this is true) and accepting that clean, brand new, boxed iMac Pros are experiencing the FCR issues, I would agree with your conclusion that there's a bad "lot" or "batch" of them out there.

Still, there are no hard indisputable final conclusions or solutions, albeit lots of anecdotal evidence that "something" is wrong.

Sure hope it's just a software/firmware issue and not a hardware issue.

Let's give Apple a change to respond next week with their take on all this, and go from there.

All the best,

My conclusion was a bit different, if people got their Mac replaced for 3 times they probably not from the same "lot", the issue report started a couple month back and if mine brand new Mac has same issue then its defiantly not from same "lot"

so I'm leaning towards software issue conclusion, I very hope.

What bothers me is, that issue is at least 4 month old, why apple checking it only now.

There are others and I'm one of them. I guess because it was an Apple product and cost nearly $NZ14K, it would get sorted without my intervention, but it does get annoying. My new iMac Pro (64GB 10-core Vega 64) arrived a month ago and I have been running it for about three weeks now, mainly using VectorWorks CAD and a bit of Parallels (MSOffice). Always had the problem of it shutting down and re-starting overnight (most nights), and sometimes during the day about 5 minutes after waking up from sleep. Started turning it off myself every night to avoid that, but it still does its own thing sometimes during the day after waking up from sleep. So, there are probably a few others out there that just aren't peeved enough yet, or think it is their fault due to some old peripheral they have.

Well, that's exactly what I'm thinking myself. An iMac Pro restarting when it's doing nothing, after sleeping, well... for a lot of people that's not a valid reason or alarming enough to call Apple Care. Bottom line is that most tasks on this or any other iMac Pro seem to be done correctly and very fast. Most, but not all. Not in my case. And luckily I found myself a task that makes an iMac Pro lose his s**t every single time. A task that a late 2014 iMac with exactly the same versions of the same software installed, can do without flinching.

I reckon this is something engineering can actually work with.

Let's see when I'll get my call... In the meantime, hang on in there everybody and whatever you do... don't put it to sleep or feed it DV-pal mov's after midnight.

Hmmm, it looks the same at first glance but it's probably quite different. Freezing doesn't mean restarting. And it does not mention the iMac Pro in particular. I think this was just an issue with parallels that could be seen on any Mac Machine. Correct me if I'm wrong for some reason. Also, I've never used parallels...

iMac Pro restarting because of a problem?
