All contents of /Applications restricted by SIP
I'm running Big Sur 11.6. Since ~3 weeks ago I can't update/delete/install any apps. As per /System/Library/Sandbox/rootless.conf, in the /Applications folder only the Safari app should be restricted:
mac$ grep -i "\s+/applications" /System/Library/Sandbox/rootless.conf
/Applications/Safari.app
mac$
but the "ls -laO" shows everything in /Applications is restricted (showing only an excerpt of the output):
mac$ pwd
/Applications
mac$ ls -lnO
total 280
drwxr-xr-x 3 501 20 restricted 96 May 10 13:14 Atom.app
drwxr-xr-x@ 3 501 80 restricted 96 Sep 17 14:57 Brave Browser.app
drwxr-xr-x 3 501 80 restricted 96 Sep 21 2020 MacVim.app
drwxr-xr-x@ 3 501 20 restricted 96 Sep 16 21:51 Opera.app
drwxr-xr-x@ 10 0 0 restricted 320 Jun 29 10:59 Python 3.9
drwxr-xr-x@ 3 0 0 restricted 96 Oct 4 09:23 Safari.app
Does this SIP status of all apps in the /Application folder explain why I can't delete/update/install any application? Another symptom is that the "Move to bin" option doesn't even show up in the pop-up menu when I right-click on anything in the /Application folder.
If anyone has ran into a similar issue and managed to resolve it, I'd really like to hear your experience. :)
thanks!
