The last driver Wacom for Mac, driver 6.3.16-10 (10.9x – 10.11x) ( we talked about in the french Website if you click in this link ) is out and it doesn’t appear in Wacom Desktop Center. In fact, there were big troubles with it.
It was impossible to move you document with Pan/Scroll if you selected it in the driver. Even you replace it by Keystroke… Space to get the hand tool.
Get back to the previous driver if you need to change itand go to the Wacom driver’s page.
