Hello,
I have the same problem as here ( [https://forum.pdpatchrepo.info/topic/3619/multiple-mice-and-keyboards-as-hid-not-for-x-input/4](link url) ),
but for mac osx.
I get the data from an old wacom pen- tablet (graphire 4 / cte440) using hidio.

But is there a way to keep the mac operating system from using it as mouse input?

When I plug the tablet, it works out the box as a mouse, but I cannot access any configuration settings. The wacom drivers are outdated and do not work on newer osx versions.
I think I shoud do something with kextunload command, but I cannot figure which extension is driving the pen-tablet

Many thanks in advance :-).
[ I asked before on pdlist, codelab and puredata facebook forum, but no answers.
Am I the only one using a tablet on osx with puredata :-( ? ]
