How to remove a broken computer screw?

I was working inside my Macbook trying to remove a tiny screw with a screwdriver that was a tad too large for the screw. As a result, the screw is now worn down and the screwdriver can’t get a good grip on the screw. Methods I’ve found online (use a wrench, drill a hole in the screw) won’t work because this screw is very tiny. Anyone have suggestions?
