If you have a low cost tablet sitting on your desk side to side with your Mac: code [dot] google [dot] com [slash] p [slash] hyperpen-for-apple [slash] The driver unlocks the capabilities of your tablet so you it doesn't run in mouse mode anymore. Pressure support, reduced jitter and multi monitor support are some of the features provided.

Sorry for the clumsy notation, but as a new user I am not allowed to post web links. [dot]=. and [slash]=/ if you ask

Kind regards
