Revising applications sharing and permissions
Reviewing the Get Info panel for a number of applications, I found a variety of names including some that I never heard of. Who are these people? In many cases I do not have Read & Write privileges, yet have used the applications without trouble. In all cases, I have been unable to ever use the minus sign at the bottom of the Get info panel to delete a name. I can ony use the plus sign to add names. Is this normal functionality for OSX applications?
