I have the voodoo rehabman-kext and the Tuouchpad.prefane successfully in
my Medion Akoya P8610 with Sierra 10.12.3 Beta 4 on 17.1.2017 to run.
Unfortunately the moving of Windows does not go, also the stroke of link with 2 fingers for messages is not synonymous.
But the most important is the double click and right and left mouse button go.
