Apple Diagnostic M1 MBP Freezing

I just spoke to an apple advisor this is a bug in 11.3.1

Just spoke to someone and this should be fixed in 11.3.2

I spoke with a second technician from apple support and it IS a bug in 11.3.1

I spoke today with Apple support.

They told me that it is a known bug and they will fix it with a small priority.

Thanks for returning with your report.

Have received a couple of replies asking; why should you want to check your computer if it is running ok..." I say Is like buying a car and your central console doesn't works and you can't check your ABS brakes and Airbags work properly and the technician tells you: "but why do you want to check your car?...."

Go figure.

In my post above, immediately after updating to 11.3.1, Bluetooth acted strange requiring me to enter my admin password to turn it on, then once it was on, I could not turn it off.

This alone prompted me to run Diagnostics where I found it would lock up immediately at the progress bar. That's when I knew something was wrong (both in the operating system AND with Diagnostics) so I took it in to the Genius Bar...at the very least for a data point for Apple & log the issue with them.

Running Diagnostics without any reason should be perfectly OK to do at anytime, not just when something seems wrong. If Diagnostics itself crashes, then there is indeed something wrong somewhere since it should NOT be crashing or locking up.

Online or offline mode, either way it is run, it still crashes/locks up solid once the progress bar appears on-screen. A force-shutdown (hold down power button until Mac shuts off) is then required to restart it.

To all those being affected by this issue, please take the time to report it directly to Apple. The more that do, the sooner the issue can potentially be resolved.

@AppleM1

I cannot confirm this issue. My cam is working properly and has not been removed from the system information. But I have installed MacOS 11.4 from scratch on. Maybe this could solve your problem, too. After a prior Time Machine-backup worth a try.

In my case I had contact to a technian on Monday. I tried the offline version of diagnostics and it was freezing. He had the same issue with his own MacBook.

Then he activated something at the servers side and I could do online diagnostics.

But I didn't see the result. I asked him to send the protocol to me, but it was not possible.

He said, that everything would be ok.

He wants to contact me again today.

When you buy a new Mac, you get 90 days telephone support FREE. This problem is complex enough that a few helpful hints are not going to fix it.

I recommend you contact support.

Does anyone else has this problem? Long story short;

a) Big Sur 11.2.3 Apple Diagnostics ran just perfect

b) updated to 11.3.1 and now Apple Diagnostic freezes right before starting the test, actually it freezes when it says: test could take a minute (whatever) and the that’s it; cursor frozen, and trackpad doesn’t even does the click.

another thing, had the same issue with another M1 MBP which I returned it for this issue, and ran Apple Diagnostics because Apple TV+ froze randomly and was asked by Apple care to do the hardware test.

thank you

Are you having some bigger issue here... why running the Diagnostic before and after updates makes no sense otherwise. If you have no issue then don't make it an issue.

Agreed. On M1 MBA. Previous big sur OS I was getting stuck in a recurring circle when choosing language in Diagnostics. On 11.4 I’ve passed that step, chosen online diagnostics to send hardware info to Apple, downloaded the diagnostics hardware and began to run it, at which point everything freezes. Screen states ‘Checking your Mac…About 1 minute remaining’ but there has been no progress for 20mins now. Cursor also frozen, trackpad does not click & status bar empty.

The laptop seems to be working fine apart from this. But like others I consider diagnostics an integral part of the machine & I want it to work properly so if/when I do have an issue I can discover it. Right now I can’t tell whether or not there is a hidden issue & that’s not acceptable on tech you spend a grand on.

fingers crossed for a quick 11.4.1 patch otherwise it will be a trip to Apple store to get resolution.

I have the same issue, since the update on 11.3

I have bought my notebook only there weeks before the the update on 11.3 came, together with an adapter for ethernet HDMI an USB. After the update the adapter didn't run anymore. I was told by the apple support to make the Apple Diagnostics and it Stucks at the same point. I have got an new adapter from my purchaser. This worked very well. But I was in doubt because of the diagnostics. If the adapter is damaged maybe the notebook too. So I gave the notebook to the dealer wich sent it to apple. They have changed the logic board and the Touch-ID. Yesterday I have installed 11.4, but the problem still exists. So I have contacted the support again and I'm still waiting a solution.
