I'm trying to change an option in the info.plist file, but every time I try to change it, an error box says that the file cannot be unlocked.
To try and change the permissions of the file, I went to the file's info, but I couldn't see my name on there.
When I tried to add myself as a user, it didn't let me add a new user, saying:
The operation cannot be completed because you don't have the necessary permission.
What can I do?
