    long time lurker, first time poster

    last night i changed the permissions on my macbook to stop my files being shared. now when i log in i cant get past the grey boot up screen

    i was told its because of problems created from changing the permissions.

    i booted up holding shift and nothing happened
    i booted up in in verbose and it says theres no posix_spawnp("/usr/sbin/mDNSresponder", ...) over and over

    i booted up with cmd+s and got

    If you want to make modifications to the files
    /sbin/fsck -fy
    /sbin/mount -uw

    If you wish to boot system
    exit


    I dont want what to do here, Im afraid to start messing with it. I really need to get the files in my HD, I'm doing finals right now!!

    thanks for all your help

    Boot from the install disc, and run Repair Permissions from there.
