Can not seem to get Nick to hack terminals for me . I have used the go command to move him to terminal and even tried to physical move/push him to the terminal. Also tried talking to him when he was at terminal. Nothing? I know it is probably something simple and apologize for bothering you guys for something so trivial but could someone help me anyway? thanks

You mean you only make him walk to the terminal? or do you actually activate the 'hack terminal' command when you literally put the crosshair on it.

Because if you give him (and other companions) the 'go' command, they only take place in that position. If you point directly at the terminal you should get the 'hack terminal' option. Same with Cait and locks..
