I was trying to run a command to fix a different issue, but when I cut and pasted the string there was a space in it and this is what was run:
sudo chmod 000 /System/Library/
Now when I try to open terminal, it just sits there with a blank screen and nothing loads. This started almost immediatey after I ran that command. Any ideas how to reverse this back to previous permissions? I did try repairing disk permissions, but that does not seem to have solved it. Thanks for any help.
