I think you'll be okay! If you feel comfortable opening your MacBook, do that and use compressed air to blow them out.

If you don't know how to do that or don't feel comfortable you can put you computer up on some drinking glasses (carefully!) this will make the ants feel uncomfortable and want to leave. put a utensil from the laptop to the table so there's a way for the ants to get out.
