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.

chmod 775 /
