I think I am experiencing permission problems on my Mac. I am running an iMac with macOS Big Sur, recently updated to 11.4, though the problem has been around for a while.
There is one application which cannot save an existing file (though it can save a new one). As part of the trouble-shooting process, I logged in as an alternative user, and it seems to work properly. I conclude that it has something to do with who can do what.
I have also saved the file to an external USB flash storage, which is in ExFat format. This is from my normal account. Again this works perfectly, so I conclude that saving on a volume with no specific permissions is OK. I doesn’t work if I save to an external drive formatted with HFS+ or APFS.
This leads me to conclude that the problem is one of permissions, possibly on the
~/Library directory. Comparing permissions on the Home directories, I get:
drwxr-xr-x+ 11 irving staff 352 27 May 14:32 irving/ drwxr-xr-x@ 97 mark staff 3104 26 May 09:54 mark/ drwxr-xr-x+ 13 something staff 416 26 May 09:57 something/
mark directory is for my normal account, and the only differences I can see are that final symbol (
What are the correct permissions for a Home directory, and how can I ensure that they are all set correctly?
