Ive always wondered why this happens.. Every single major MacOS update, Wacom Cintiq/intuos drivers stop working.. No pressure sensitivity, choppy lines... Is the ball in Wacom's court here or Apple's? If it's Apple, what do they keep changing that messes up the pressure? It just strikes me as odd. - I'm not complaining, the Wacom updates usually happen during the public beta or around release, it just strikes me as odd. Very good reason not to install betas on certain machines anyway, even if it is, consistently the *only* thing that breaks for me.
