How do you mean "nix get nuked"? It's no longer available on your PATH? If so, you may want to take a look at this issue: #3616

This happens because macOS updates overwrite the various profile files that we write the "please add Nix tools to the PATH" snippet to.

Unfortunately I’m not able to be very specific since I removed and reinstalled nix to workaround the problem. From what I remember the whole /nix directory appeared to be empty, but I learnt that during one of the first checks I did and I’m now afraid I missed something less dramatic like the issue you are mentioning.

I’ll report more information here in case I’ll encounter the problem again.

Since it doesn't sound like we have anything actionable here for now, I'm going to tentatively close this specific issue.

If you do run into this again and open a new issue, can you include a single copy of the output of the process in your terminal instead of the split stderr/out files? (I didn't see anything obvious in the stderr log here, but it's generally more helpful to see any error messages in context rather than separate.)
