In theory, so long as the tablet supports the standard MacOSX tablet events, it will work.
But really, trying it out is the only way you'll know for sure. There will be a MacOSX universal binary of ArtRage 2.2 Free version very soon. That will use the same tablet input system as ArtRage 2.2 Full version.
If you can get the tablet on loan for testing, and have the 2.2 Free version of ArtRage, you'll know if you can buy the tablet (and ArtRage!)
AndyRage's mantra for graphics engine code:
"Sure - how hard can it be?"
