Mac Pro (Late 2013) GPU (Driver) Issues

[o_O]

I've been having GPU hangs more frequently, in-fact 15+ within the last day:

Update...

I left my Mac Pro with the Apple store a week before Christmas, that was the third time leaving it there. On the second trip they were supposed to wipe the drive and run diagnostics, and when I got it back they had not wiped so I brought it back so they could wipe and run those diagnostics.

I got the Mac Pro back yesterday, they told me they had wiped it, reinstalled the OS and ran it nonstop with no issues. I get it home and found that they had installed Sierra on it, after I had repeatedly told them to leave it on El Capitan (as I don't know yet whether all my software will work on Sierra without making purchases, etc...)

Does anyone know if I can install El Capitan on a machine with Sierra? I've heard that you can only install newer Mac OS, not older versions?

Anyway, that probably means that the week of diagnostics that they did was on Sierra and not El Capitan.

That's the second time they did not do what they told me they were going to do, wasting more of my time....

You can install any supported Mac OS on any Mac in any order. Go to App Store and download a copy of El Capitan and create bootable USB drive with this terminal command:

sudo /Applications/Install\ OS\ X\ El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/USB_NAME --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction

Replace USB_NAME with your actual USB drive name and be sure to format it before this command as GUID (Partition Map) and Mac OS Extended Journaled (File System).

When terminal command is finished, boot from that USB, erase Macintosh HD and Install El Capitan on that erased disk.

No beachballs with this error. But GUI will become unresponsive for a few seconds. Then it recovers.

Possibly VM related (though I suspect unlikely). VirtualBox is not installed. VMware Fusion is installed, but not running

Since the update to 12.2 - 10 days ago now - i am running a shockingly stable MacPro. The crashes are gone. There are a "WindowServer_Mac-Pro.wakeups_resource" events logged, but that's it. No repair, no changes of whatever kind. Did they do some BIOS-Updates with 12.2 as well? in 12.1. i did have these nasty crashes - getting logged out as reported here. In Bootcamp/Windows 10 there are occasional graphics-driver crashes, but there are no more "notifications" on screen "...became unresponsive and was recovered". No changes in Windows-setup as well.
I am just a bit confused...

EDIT 26/01
12.2.1 still no crashes.

 

[o_O]

My system has increasingly become quite unstable and almost unusable; It seems almost everything hangs now, including Finder with regularity. I guess that I'm going to have to backup all my data and take it into Apple, as it's starting to get aggravating. Hanging is not the only issue either, as applications such as Final Cut Pro X are crashing often:

Hi everyone - I am new so apologies for any mistakes that might occur.

I wanted to see how everyone is getting on with this issue. I have a Mac Pro and like the initial poster had, I also had the same. My machine firstly had one card changed, than back it went for another card to be changed, then back again for the motherboard. After this, the machine still hung. It was eventually changed. I now, for the last few months, have a new replaced Mac Pro.

Since I first got the new replacement, there is a glitch that appears across the screen upon loading of the OS; only for a second or so before it continues to boot up. This I was told is an OS software problem: I am on sierra now and so I let that problem go for now. My latest problems is the hibernation of my mac will not awake the monitor, and at times, the monitor will flash as it tries to connect - think rave at midnight. It completely glitches, across the whole screen until I pull out the monitor and plug it back in. The computer works fine once I plug the monitor back in. Sometimes the monitor will just hibernate and not wake up, also without the manic effect flashing across the screen, and when I unplug the monitor, it will be fine.

I have added this part about the second replacement machine as I wonder if this all relates to the initial post. With my old machine that had the hung GPU, to regain control of the machine, I would have to pull out the monitor and then gain control to reboot. There seems to be a strange resemblance here in some respects with the GPU problem as I have to unplug the monitor to regain the monitor just as I did with the GPU.

I hope this is helpful.

Latest OS update supposedly fixes some sort of freezing issue.

As for me, I've not updated since the early GM version I had back in September and not one freeze since then.

 

[4God]

I wonder if this helps?

I have a 6 core with D500's and have been waiting to upgrade to Sierra. El Cap has been good so I don't want to ruin it.

10.12.3 helped a lot

 

[Idolum]

Whenever a new OS X version is released I don't even check the features anymore but simply check this forum to see if the crashes are addressed. I am still on Mavericks without a single crash. Everything else is secondary. The last professional Mac I owned that I had to reboot was this bad boy:

This is crazy, machine is very unstable doing nothing ! Flurry screensaver crashes WindowServer almost every day.

 

[iigsie]

I've had the windowserver error and gpu panics. I originally took to Applestore while still under warranty. They wanted to replace the GPU's but this was blocked by someone higher up. They ended up replacing the little ribbon cables, which did appear to stop the issue for a few months, strangely just until the warranty expired. They also insisted on wiping my computer.

It started happening again mid december last year, so I did some testing.

As others have said, the issue does not appear under Mavericks. Later versions have the issue, until 10.12.2, which so far (1 month) has not had a single gpu/windowserver issue. I've been able to put to sleep every night and it always wakes up.

So it seems like there can be several issues to the fault on D300 computers.

The

MP is going for a service "meeting"

I'll keep you posted....

The only logical conclusion is that there are multiple issues here.

I had the windowserver and GPU panic issues really bad - more than once a day. They told me the replaced the ribbon cables, which fixed the issue for about 6 months, then it came back until I updated to 10.2.2.

So some people have bad D300's, some people have bad ribbon cables and for the others it appears to be a driver issue.

My Mac Pro has be in and out of servicing for several times. Apple insisted on wanting to reproduced the problem and while my Mac Pro was at the service centre, it worked fine. Now my Mac Pro is back with me, I've had 2 freezes and 1 auto-restart.

Here's what I think.

Mac OS does not work well on this Mac Pro. It could be a hardware problem, but I doubt so, but since I'm not an engineer I can't confirm.

Even though my Mac Pro is still under warranty, I've given up ever getting a perfectly working Mac Pro already. Whenever it has freezes now, I will just force restart. Whether or not I send it in for repairs, the end result is the same.

There's no other way to put it except to say that this is a flawed product. What a shame.

I had a few situations in Windows (8.1 Pro) where Driver Stopped Responding....excatly what WindowServer LOG files reports....driver stoped responding for more than 10s.

I can˙t believe that this cannot be fixed because there are a lot of MP6.1s which work 100% stable.

My MP is still at Apple Authorised Provider. They called me to say that Apple send them all possible tests they ever run, and MP passed all of them with no problems at all. Now, because I sent them computer with tons of evidence, even with video clips where MP froze live with "About This Mac" dialog is open, they want to analyse this even further.
They can˙t escape the fact that there is something wrong.

Fortunately that MP is not my primary machine and I˙ll give them as much time as they need to fix it.

That's exactly the same situation I am in.

Just because their engineers cannot reproduce the problem does not mean there is no problem. It just means the engineers can't reproduce the problem.

Anyway, this is a flawed product. It has been years and they still can't fix it so I doubt they will be able to do anything going forward except to test and do further tests and waste their customer's time.

There is a flaw and now is too late do to any corrections, only thing they can do is what they are actually doing - replacing parts.
