Sharing and Permissions on Mac HD
Can't make any changes in Sharing and Permissions settings on any of my Macs, I get this_The operation can’t be completed because you don’t have the necessary permission.
I am logged in as the only user of each of the Macs and have always been able to change all Sharing and Permissions settings and now cannot. ???? Thus I am unable to access one of my Macs from the others in Finder even though on the same wifi.
MacBook Pro 13″, macOS 13.1
