I downloaded the new software update macOS Monterey 12.0.1 on my MacBook Air yesterday and today I got a notification saying ‘volume hash mismatch’ for context the rest of the notification said
‘hash mismatch detected on volume disk1s5
macOS should be reinstalled on this volume’
I’m quite confused as what to do next and if this is going to cause a problem on my Mac
MacBook Air
Hi amna2k1,
We understand that you're seeing an error message after installing macOS Monterey. In this case, let's try reinstalling macOS using these instructions: How to reinstall macOS - Apple Support
Take care.
Hi
in my case only appears the message and the system continues working but unstable
the problem appears random
I just got another Volume Hash Mismatch error. Problem persists. So far the only application impacted is Mail. It has crashed twice and had to reindex email upon restart.
Thank you for the follow up. Helpful to know the RAM is factory. Hope it stays stable for you.
Volume Hash Mismatch?
