The following error message appears when I attempt backup using TM; "You do not have appropriate access privileges to save file “.0019e33d49f6” in folder “Time Machine Backups”.To view or change access privileges, select the item in Finder and choose File > Get Info." Spotlight can't locate this file, I've ran disk utility to verify and repair the internal drive, verified the external, no problems on both counts. I even tried allowing read & write privileges temporarily to everyone on both drives, but no luck. Any suggestions? edit: I notice under sharing and permissions on my root\user\matt (that's me) directory it has 3 users, Matt, Unknown and everyone. I can't change Unknown away from read only, is that normal?
