I changed the permissions on my hard drive from Everyone to No One.  I understand now that's a no-no.  Now I get the startup screen that's stuck at the apple and the sticks rotating in perpetuity.  I've tried everythign I could find, most unsuccessfully. 

Reset PRAM - fail

Reset SMC - fail

Boot in safe mode - didn't work.  I was going to try to boot from a clone on my external HD.

Boot as singel user and try CHMOD - fail

etc, etc


I'm working out of state and my recovery disk (whatever it's called) is back home.  Other than having my wife find it and sending it to me, is there a way download the disk and burn it to DVD and use that?  Do you think the geniuses at the apple store an hour away could help w/ that?  Do you have any other ideas?

MacBook Pro, Mac OS X (10.6.8)

    There is no way to download the disk. You could ring the Apple Store - if you quote the serial number of your Mac they should be able to supply you with a disk at a small charge, but you might just as well get your wife to FedEx it (or whatever).

    Boot as singel user and try CHMOD - fail

    In single user mode you are root, it should not fail. You did something wrong. Follow these directions:

    Boot into single user mode -

    Once you are at the prompt then:


    /sbin/fsck -fy /

    If the filesystem is clean then:


    mount -uw /

    Remore the ACL entry from the boot disk:


    chmod -N /

    And finally:



    If this does not fix the issue then a trip to the Apple Store would be a good idea.

    Start in Single user mode again like before, but use these commands,

    Note: there must be a space between the / and that which precedes it. The font I used is intended to show this.


    mount -uw /


    chmod 1775 /

    I'm glad you can access your disk again.


    "but my HD still has stuff like the new CD I recently purchased before this fiasco."

    "What do I do now?"

    I don't understand what you mean here.
