MP 6,1 Mac Pro 6.1 Monterey - Crashes in Sleep

[vddobrev]

For me it all started wit Catalina Security Update that bricked my MP6,1. The CPU Riser card has been replaced in an authorised service centre, with a warranty of 3 months. What do you know, 3 1/2 months past, I start getting alarms fro DIMM 3,4 proximity sensor and kernel_task taking 100% CPU. After dusting, it was OK for a while. Then all of sudden the DIMM 3,4 sensor disappeared from Mac Fan Controls.

Today, the sensor is back, and I get kernel_task 100% CPU and fans spins 100% no matter what. The sensor reports 95°C momentarily (causing the kernel_task panic), then drops to regular 38°C.

I have to question what kind of spare/replacement parts they use... their policy says they can use refurbished or new... What chances do I have arguing with them that they supplied a bad part?

Does anyone have any good pointers on locating the DIMM 3,4 sensor on the CPU riser board? All I can find is this:

DIMM 3,4 proximity sensor indicating high temperature - Mac Pro Late 2013

hi, I’ve been having high fan’s rpm for a long time. After installing Macs Fan Control 1.4.11 I’ve realised that the DIMM 3,4 Proximity sensor is showing more than 85º C or more always. Even after a new boot upt. I have 4x16gb RAM modules installed, but even with jus 2x modules in DIMM 1,2 it...

macOS 12.4 beta dev is out

Anyone know if the firmware has changed or updated?

Anyone know if the firmware has changed or updated?

I installed the 12.4 beta and it didn't update the firmware. I don't know if it contains the 429 or 430 firmware since this Mac already has the 430.

Anyone know if the firmware has changed or updated?

I don‘t have the installer, but those who do can just check it:
Install macOS Monterey.app/Contents/SharedSupport/SharedSupport.dmg/com_apple_MobileAsset_MacSoftwareUpdate/[HEX-GIBBERISH].zip/AssetData/boot/EFI/EFIPayloads
Then open the MP61 scap file with a hex editor and look for the firmware version.

edit: Added sample screenshot what to look for. NOT from 12.4 but from macOS_12.3.1

Damn I got a freeze while screensaver was running. I will post in the other thread, I think this issue was fixed and the only one remaining was this sleep issue. But Mac Pro was connected via HDMI which was always problematic, I had no freeze in weeks with mini display port.

Mac Pro (Late 2013) GPU (Driver) Issues

Damn I got a freeze while screensaver was running. I think this issue was fixed with macOS 12.3 and the only one remaining was the sleep issue which is fixed by firmware 430.x that was pre-released in macOS 12.3 beta5. I had this freeze with HDMI which was always problematic, I had no freeze in...

BTW I've install macOS 12.3 beta 5 (then opted out and updated to standard 12.3.1) which came with 430.x firmware, I will update you.

Latest Big Sur CustomerSeed macOS 11.6.6 (20G604) still contains 429.60.3.0.0

Update #2: Not so good. My Mac Pro crashed overnight. I was optimistic and left it running with most of my apps open, i usually Quit all my apps to avoid crashing. -- so I'm unsure what has caused it to crash .

Also, I have noticed with the new firmware it takes longer for the Apple Logo to display on bootup -- no big issue, just an observation.

Tonight, i will quit all my apps and see if it will survive or crash.

It's been a while since my last update. The good news is that I have not experienced any crashing for more than a week. The firmware: 430.100.23.0.0 seems to have worked in fixing the crashing issues. I'm also running Monterey 12.3.1. I'm glad my MacPro is back to normal.

Well, my issue with DIMM 3,4 proximity sensor seems to be worsening - it now show sporadic values just randomly, and causes the kernel_task to take 100% CPU and machine becomes unusable. Sometimes it takes 5 minutes after boot, other times hours.
Good thing I am covered by UK Consumer Law 6 year, I will be bringing it in for service.

This thread has gotten so long, I'm no longer sure if it still pertains to the original post about MONTEREY/SHUTOFF (CRASH) DURING SLEEP *but* I tried #5 from this article and so far, so good, and it seems to make logical sense (aside from why "hibernation" is in there):

Please forgive me in advance if I'm repeating a fix already mentioned.

Installed 430.100.23.0.0 a few days ago and it's just crashed after sleeping for about an hour!
Not impressed with Apple to say the least. MP6,1 is less than 3 years old and ran perfectly until firmware 429 got installed along with 11.6.2.

You are not off topic, thanks for the information. Many have tried this, but eventually it crashes again, especially with MacPro6,1. The issue became common when Apple released a firmware update during 12.1 - 12.2 which seems to be the likely reason. A firmware fix "seem" to have fixed the issue during the release of 12.3 beta 5 for MacPRO6,1, but when Apple released the final version, it was not included, giving speculations about the reasons.

The thread is dominated with MacPro6,1's issue since it is seems the most effected (or at leased voiced).

Strange I'm really stressing my Mac Pro with continue short and long sleep and 0 issue since 430.xxx firmware. Are you connected via HDMI? HDMI is problematic, much better to use MiniDisplayPort.

Display port in use. Was on 11.6.2, now on 11.6.5. Went only a few days on 430 before crashing. Had only been sleeping for about an hour when crashed.

I'm testing HDMI too since this late morning, no issue at all since 430.xxx. maybe you got a freeze/crash due to other issue like overheating, battery. At least on macOS 12.3.1 I have no longer freeze in long or short standby, in safari 4K content, rock stable since 3-4 days for now, completely different from before

 

[vddobrev]

I sent my MP6,1 for service (bad temperature sensor DIMM 3,4 Proximity), let us see how long it will take for Apple UK to fix it or replace it. The service manual states to replace the CPU riser card in such a case, and I had it replaced once already.

In the meantime, as the thread starter, I am watching this thread with great interest to see when and if this will get resolved.

I upgraded to 12.3.1 a little over a week ago. I went from daily crashes to none at all. ...until today. So yea, much less frequent but not solved imo. I have a 2017 iMac ftr.

 

[ikir]

My Mac Pro still no freeze/crash, perfectly stable with firm2are 430 and Monterey 12.3.1
Mac Pro thermals are optimal because cleaned every piece of it and changed thermal paste, but still with 429.xxx firmware I got frequent freeze in standby not it is rock solid. the issues are two, thermals and firmware in this case. I suggest everyone to clean and change thermal paste, if don’t have the experience to do it, pay someone who can do it, pay attention to don’t damage your Mac Pro, then wait for next beta released to firmware 430 or if you can’t wait just install macOS 12.3 beta 5 then opt out beta and update to 12.3.1

I have the same issues for months now. Things got a lot better with the Monterey updates. I also reset the energy power settings to default for some time now. I still get some crashes from time to time but the thing I have noticed is that they occur mostly when I have my iPhone connected and the computer goes to sleep.
I haven't noticed the same with my external hard drive for example or with a usb or a card reader.
If I don't have something connected when the computer goes to sleep (except the display(apple LED Cinema Display 27 inch)) it can run without a crash for weeks.

Humm…I will try with my Apple thunderbolt monitor only and let it sit and see how long it takes for a crash. Have it hooked up to a Dell monitor (Matted screen). Will confirm if something happens. Mac Pro is my back up system now, so I can let it idle without anything and see what happens. I will also unplug the Ethernet and turn off the wifi. Might be a good test to see..

I give up. I ordered a Mac Studio that’s set to be delivered May 30 - June 6. I just can’t stand the idea of what repeated, random shutdowns are doing to my data. I’m basically paying $$$ for Apple to be more responsive to any problems with the Mac Studio since they seem to have all but lost interest in solving this Mac Pro 6,1 issue.
The trashcan is being retired to bookshelf decoration duty just as the new new Mac Pro is likely to be announced at WWDC.

I am pretty sure they will fix the sleep issue eventually, but you can disable the sleep function, if the MP6,1 still serves your purpose, then spending on a new Mac Studio is, well, overspending - but the choice is entirely yours.

There’s been no indication that Apple will fix it. Multiple OS updates haven’t fixed it, and Apple is barely acknowledging the issue at all. A computer that doesn’t sleep is a computer that doesn’t suit my needs to be ready exactly when and how I want it to be ready. Two decades of reliability from Mac and iOS devices have set that expectation for me.

The important thing is that you all understand the firmware 430 FIX the sleep issue. I installed since 10 days no isse at all with both HDMI and MiniDP

It has been fixed, if you install macOS Monterey 12.3 beta 5 you will get firmware 430. Why it was pulled form final version is unknown but many users are testing it without issue at all. Rock solid, naturally if you have solid hardware, since most of these Macs have 7-8 years a clean and change of thermal paste should be a must.
