I also used to have one years ago, like other solutions it mapped some gestures to some functionality, but at the end it just moved the mouse cursor and simulated mouse clicks or double/right clicks.
Really, macOS doesn't really support touch points. I'm astonished how many people don't get it on this thread.
As it seems like people are using "touch" things on macOS and - for them - it's working well... perhaps the "macOS doesn't really support touch points" thing isn't really a problem?
When people can't tell, is it really needed? I mean, it's already working. At least for Wacom tablets. ;)
Pretty sure (~85%) the "touch" functionality used to work fine.
