I have a mac 10.1.5 just to let you know. I have trouble mounting .dmg application such as games and other files using disk copy. I got some searches leading me to downloading Repair Privileges. When I run it and have it ask me which mac os x volume I wish to reprair. I choose macintosh HD. As it scans the files it crashes around item 1065 (varies). Not totally crashed but the application Repair Privileges stops running. Well my probly is I can't mount .dmg files with disk copy and can't get it repaired.
