TabletMagic is an open-source driver that allows Mac OS X to communicate with older model Wacom tablets with a serial interface and TabletPC digitizers.

Supported tablets include the UD, UD-II, ArtPad, and ArtPad-II (ArtZ-II) models. This is an ongoing open-source project to bring full support for all serial Wacoms. See the accompanying documentation in the download for details. Source Code is available.

Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.
