MacBook Pro reports after disk utility lists broken seal

That remark doen't help bc I knew what I was talking about and it was mentioned in the previous mail.

But that is not my point.

The point is that even after a clean install the diskutil reported that the seal of the system file was broken.

But as it doesn't affect the performance, it seems not a big issue.

Therefore I asked the Community if any person could advise.

I also have no idea what has broken the seal, so that's another question.

I don't need common remarks as reinstall or how old was the macOS installer or d/l a new version, because that is all done and checked.

Summarizing:

1. is it possible to repair the broken seal by reinstalling or whatever method?.
2. what could be the cause of the broken seal?

Thanks André

I know where to find the operating system and the read-only protection, that’s no secret.

The mba is eligible to run macOS 11.7.10 Big Sur. At first I did an upgrade from Catalina to install Big Sur but the second time I did a clean install and the result is still the same, a broken seal is reported. It does, however, not affect the performance. Therefore I don’t worry too much about it. Tough, I want it fixed. Could any one please advise how to fix it?
