I have a MacBook Pro middle-2010 model with a 240Gig HD. I changed permissions on the HD b/c I needed an administrator account full access to several others and thought that it would be easier to just change the permissions on the entire drive. I allowed me and several other administrative accounts full access to the entire drive and said 'Apply to enclosed items' Now I know what that does. I'm stuck at the loading screen, and I've tried both Verbose and Single-User, even Safe boot. Verbose comes up with: launchctl: Dubious ownership on file (skipping): /Library/LaunchDaemons launchctl: Dubious ownership on file (skipping): /System/Library/LaunchDaemons launchctl: Dubious ownership on file (skipping): /etc/mach_init.d I've tried 'diskutil repairPermissions /' and some other chmod commands. Nothing has worked. (diskutil b/c I'm in single-user mode) I don't have access to the OS disks RIGHT NOW, and I'm going on vacation and I need it working by tonight. Any help would be greatly appreciated. If it helps, I do have access to the root account, and I am an administrator (you should've probably inferred that by now) Could you also tell me if you think the OS disks would help? I imagine that the DiskUtility framework wouldn't be accessible b/c it's in single-user mode when you boot to repair...am I wrong? Don't know. Thx. Thanks Hunter EDIT: Okay, JUST SAW the 'Mac won't boot' wiki post. Sorry to all who I aggravated.
