Essentials on Mac with Huion GT220v2

Hi, everyone-

I’m running Essentials on a Mac with a Huion GT220v2. Everything works fine except the pressure sensitivity. Any ideas? I called Toon Boom support and there is an option that help under preferences->advanced for Windows but no real knowledge for a Mac.

Appreciate any support!

It happens the same to me, but with huin gt 191 kanvas, any results?
