[summary: The HV bits are extremely well insulated. But even if they weren't, the energy stored is insufficient to do anything other than give you a zap similar to what you've experienced before on dry days, reaching for a doorknob.]
So get yourself a long torx driver and some simms. Do it now. You'll feel better (and so will your Mac).
