Volume Hash Mismatch

hmm

I even did a total re-install of macOS Monterey Beta 2 (erased the SSD and a fresh install).

And yet again, this "Volume Hash Mismatch" is persistent

Hmm

So, I did:

fsck_apfs /dev/rdisk1s5

From Recovery .... on all Volumes and the disk itself.

Back in macOS MR B2 ... Still getting this annoying notification hmm

same... now just waiting for another quick update from apple.

Same

I just started getting this today. The system is also unstable, I've been getting random Kernal Panics.

Update: I tried Beta 3 ... and now running Beta 4 .... on my MBA ... and I'm still getting them.

I have to say, it's gotten a bit worse ... since Finder and other vital "vital mac apps" crash and they won't re-spawn. And I end up with no apps running (read: showing). Funny when you just have the WindowServer app running and everything else has crashed, and didn't re-spawn.

Luckily pressing the PowerButton does pop up the "shutdown window" ... and I can restart my MBA from it (and not force...)

BTW: ... something I noticed is I was getting the error when using / having Safari open ... so I'm going to test using Firefox instead .... and try extra not to start any other "Apple apps" (just 3rd party apps) and see ...

I got the volume hash mismatch but it is not my volume where I downloaded macOS Monterey

Having this issue too, though without the popup and on Big Sur. I've discovered that a sudo purge works as a quick fix, though it ends up coming back. You can run it over SSH too if you can't open Terminal anymore. Hope there's a real solution for this soon.

Ok turns out my issue was caused by failing RAM, replacing it solved my issue (I have a MacBook Pro that has user-upgradable RAM). Probably not related to the issues in Monterey.

Is anyone still getting this issue with 12.1? I often get the notification and also experience a very unstable system with various app crashes. This did not go away with a completely fresh install (erase disk).

For what is worth I’m getting this issue on a 2019 16’’, another 2019 13’’ I own is running fine.

My MacBook (early 2015) has OS Monterey 12.01 with the same problem.

I am facing this same issue with my 2021 16 inch MacBook Pro with M1 Pro chip. Earlier when I bought this laptop it was working just fine with Monterey 12.0 but when I updated to Monterey 12.1 I started seeing this "Volume Hash Mismatch" notification. Also, all of my regular use applications like Docker, PyCharm, VSCode, Slack, Chrome & Python are now crashing every 10 mins. I contacted apple support & was told to reinstall the MacOs Monterey using bootable USB. I did that & it didn't work. Then I was told to reinstall MacOs via internet recovery mode. I did that too but it didn't solve the problem. I was also asked to upload the screenshots of issues so that it can be escalated to their engineering team. Never ever heard back from the engineering team.

Then I was told to visit iVenus store(Apple authorised service provider) which is in Kothrud, Pune, Maharashtra, India. I submitted my laptop there and after a day I got it back with the freshly installed MacOS Monterey 12.1. The issue still persisted. I visited the iVenus store again the next day with those same issues. I was told to install application from App Store only as the third party application like Docker, Pycharm, Slack, Chrome, VSCode & Python are not yet supported by the Apple Silicon. I went to the website of these applications and pointed out the statement which says "Stable release for Apple Silicon".

I was denied to provide any further services by the iVenus store as their support team concluded that it is a problem of the application and it has to do nothing with the machine.

This morning I contacted Apple Support again and I was told to wait for another day so that they could escalate this issue to engineering team.

I will be receiving the next call tomorrow at 11:30 in the morning. I pretty sure "incapable apple" wouldn't be able to solve my issues.

I invested in a ****** product and yet the support team tends to congratulate me for using premium Apple product every time I got on a call with them.

Here are some of the screenshot I took recently -

Same problem in 12.2 beta2. It often appears when using safari , then Mac will freeze . I think Apple didn't notice this problem 😔

Incompetent & Incapable Apple here are few more screenshots -

BTW Apple support has denied the repair, replacement or repair of my machine.

To the most asshole company of all time -

Here is another issue while reinstalling the MacOS Monterey.
