Mac Studio 2022, M1 Ultra shut down problem

THAT report, from the Disk Drivers, says that your Drive spontaneously DISCONNECTED without checking the Directory Information back in to maintain its integrity.

That report is the evidence we were looking for.

NOW you have something actionable!

Telephone Support:

The telephone support people are more likely to work with you. They will insist that you go through the motions to eliminate software issues. But when they get to the end of their list, Do NOT allow them to tell you it's fine or there is nothing more they cane do for you!

You should insist on having your problem escalated to a specialist. Specialists are more likely to actually read your panic other reports, and to agree this is a problem and DIRECT an Apple service provider to swap things (likely mainboard) for a new one.

Apple support does appreciate what we do as Volunteers here on the forums. They can and should read what has already been posted. Be sure to tell them where they can read it. But they do NOT take our conclusions at face value -- they have their own more rigorous procedures they follow.

You MUST have a Trusted backup before submitting your Mac for service. if the mainboard is swapped out, the boot drive will be swapped out as well, and you will not get your files back.

Actually those "unsafe shutdowns" associated with the SSD are "normal". I see it all the time on my organization's Macs with that value being in the thousands. I don't think that is the source of the problem here. I don't recall at the moment why the Macs have their SSDs report these "unsafe shutdowns"....I had a theory a while back. I think those "unsafe shutdowns" may just be a side effect of the main issue.

FYI, usually when SSD's fail, you will see Kernel Panics from the SSD disappearing from the bus. The other time I see problems with an SSD it will be due to "Media & Data Integrity Errors" which unfortunately are not shown in the EtreCheck report. If you suspect an SSD failure is the cause, then run DriveDx (free trial period) and post the complete text report here using the "Additional Text" icon which looks like a piece of paper on the forum editing toolbar. The EtreCheck report did not show any Kernel Panics, so the "Media & Data Integrity Errors" value in the SSD's health report is all we have to go on for the SSD's health.

Thanks for the help! I ran DriveDx and everything was fine. No errors found.

I don't see anything in the SSD's health report to cause concern.

I guess the real question is whether the Mac Studio actually powered off during those events or whether the system would not wake up, or there was an issue with the external display. It is possible an externally connected item is causing a problem as well.

From what you mentioned, it seems like a hardware issue of some sort (Mac itslef, or a connected device, or possibly even your power source....power/surge strip, or another device on that same electrical circuit). When I first read your post....like @Grant, my first thought was a display related issue, or a system that wasn't responding correctly.

You have to determine why the issue may not show up when you take it in to have an AASP examine it. Is it because the problem is too intermittent, or is it because you left the actual source of the problem at home (see previous paragraph)? It also helps if you can figure out a way to reproduce the issue on demand or more often so that the AASP tech may actually get a chance to see an issue.

If the computer is powering off/restarting on its own....then do you see a message when booting/logging in about the computer having an unexpected shutdown? If so, the system had a Kernel Panic, so you want to get a copy of the report (I think you need to click "report" on that notice which will then show the details....copy that report & post it here) since the EtreCheck report did not see any Kernel Panic logs....sometimes Kernel Panic logs don't get saved. If your Mac is having Kernel Panics, then seeing a Kernel Panic log is critical (for us and Apple).

Unfortunately the type of issue you are having can be difficult to troubleshoot, especially remotely.

one thing that caused trouble on older Mac Pro was the power cord connection to the computer. I suggest you power down, remove the cord, and JAM it into the computer socket.

Consider downloading and running this little "discovery" utility, Etrecheck. It changes NOTHING. Etrecheck was developed by a senior contributor here, and uses mostly system calls and simple tests to collect often-needed information.

it contains little tests for speeds of devices, CPU utilization, memory usage, energy usage and a digest of recent problems, in one easy to use package. it does not even need to be Installed. Because less can be learned when your Mac is running great, best time to run is when your problems are actually occurring, if possible.

if you follow the directions faithfully, its report (pre-laundered of all personally-identifiable information) can be "Shared" to the System ClipBoard, then Pasted into an ‘Additional Text’ window in a reply on the forums.

Use Etrecheck Pro for free:

The amount of data you get can be daunting. If you POST your report, some Readers here are willing to look over those reports, and can provide valuable insights.

then start a reply on the forums, click on the "additional text" Icon, and PASTE

Is the Mac connected to a multiple socket, possibly even a master-slave multiple socket?

These can cause problems. 

General debugging tips:

Make certain you have applied all available software updates, because no one is willing to debug a problem that might have been seen and solved already.

Then you need to go through the 'regular" steps to eliminate added software as the cause of the problem:

• Run In Safe Mode, where no third-party add-ons are loaded

• create a new "clean" User account, and run with that to eliminate contamination in your regular User account

• run the diagnostic to check for GROSS issues. "no fault found" is not the same as "all is well".

Genius Bar:

if you take it to an Apple service provider first, they CAN run their diagnostics, which are a bit more comprehensive than the User diagnostics. In the very small amount of time they are run, “No faults detected” still does not mean “All is Well” but at least there are no detected GROSS problems. Unless they can find a fault, they will return your computer unchanged. Genius Bar technicians are NOT trained to read panic reports and computer logs.

When you present your computer at the Genius Bar with the expectation of a quote to repair it, you must generally meet these criteria:

• your Mac won't do anything

• your Mac fails diagnostics

• your Mac has a problem you can repeatably demonstrate on demand

one other oddball case:

• Apple online support has DIRECTED a Service Provider to replace specific components inside your Mac, such as the mainboard or display. Bring proof, such as case number.

Great advice on diagnostics...

I did this now because I found my always powered MB2 had a Kernel Panic last night when I closed it; found this morning and worried as **** because it's a 2022 Refurb and now out of warranty!

First time ever event with the new MB.

There is no record in that report or the previous report that your Mac stopped running, lost power, panicked, or crashed. Nothing.

Your studio display-- how is it connected to your Mac? Exactly what cables, adapters and docks are in use?

How did you manage to change the resolution on this 5K display to only 4K?

what cable are you using to connect the Studio display?

Is it the special ONE meter cable shipped in the box with the Apple display? clearly marked at each end with a Thunderbolt symbol?

Why is your 5K display running at 4K resolution?

There appears to be some problems with Google and Chrome.

Did you install these from the web, and only through google.com and not from any third-party site?

The 'approved method' for getting bigger text is to select the MAXIMUM Native resolution, the use the settings provided to select bigger text. These will NOT be shown to you at all when you choose 2K resolutions.
