How can I set sharing and permission on Mac os x to be -rwx for all? When I create file or folder it is read and write for me but for all others it is Read only. If there is more files just copied from USB to some unlocked folder, automatical it is read only for all other users. Because we share files it is annoying. So please help.
Set your umask to 000 and reboot, then all files will save with full permissions for everyone. Here is the documentation http://support.apple.com/kb/ht2202
