Unknown user in Sharing & Permissions
Hi, I have discovered an unknown user (wheel with Read only privileges) in the Sharing & Permissions info window of iMac, 24-inch, M1, 2021 running Ventura 13.2.1. Logged in as System, when I attempt to remove this account, a pop up says "The operation can’t be completed because you don’t have the necessary permission." What's going on?
iMac 24″, macOS 13.2
