Hi, I have a MacBook Pro Intel Core 2 Duo with OS X 10.6.6 I've been trying to run the terminal, but as soon as it opens it starts thinking and i get the beach ball, i don't get any error but then the computer starts working really slow and the beach ball keeps running around. I can open all the other programs without any problem, but when i try to run any program that involves the terminal or X11. thanks for any tip, help !!!
