Now where you see I believe, 'System', 'Admin', and 'Everyone', and changed them all to 'Read & Write'. If you're on the admin account you should only have to change the 'System' one, I think. Do the same on the sources.conf, and it should work. If not, repeat those steps on all of the folders that sources.conf is in. It should work, so try to edit it again.

It worked for me, so I guess it'll work for you.

This doesn't appear to work for me and I'm dying for editor on mac right now. I added every account possible.
