How to give permission to write to a folder?
Trying to open & work with a file in one of my folders I get a message sayign that I don't have "permission to write to the folder that the file ... is in." I have no idea how this "lock" could ahve been set or how to undo it so I can work with my files. A week ago I migrated from my old McBook Pro to a new iMac, but have not had any other such permissions problems.
