Are permissions specific to hardware or software? I ask this because I was wondering if I plugged my mac HD into my pc could I access the mac files even though they have "everybody" set to "no access"? I basically changed the permissions on my mac for eveyone to no access and now the machine wont boot. It won't even let me on safe mode. Any help is appreciated

MacBook, Mac OS X (10.6.8)

    Did you check Apply to enclosed? If so, the only fix is to reinstall. That would have screwed up every single system file on your Mac.


    See if it will boot into single user mode, Cmd-S at the startup chime. At the prompt enter each of these separately, followed by hitting return. 


    mount -uw /

    chmod 755 /System

    chmod 1775 /Library

    chmod 1777 /Users/Shared

    You need to order replacement original disks, or if your computer shipped with Mac OS X 10.6.2 or earlier, a retail Mac OS X 10.6.3 DVD, and then use the Disk Utility on it to run repair permissions.

    Reinstalling will preserve all Apple applications, settings, users, and third party applications. But good idea to have a backup, which, if you don't, is too late to make now. But If you have a bootable clone as a backup, you could just reverse clone back to the internal from that. To restore the OS from Time Machine, you'll still need the install DVD. TM won't help now.

    How are you trying to do that? You need to insert the disc then restart holding the C key.
