Each stylus producer i know provides pressure/tilt pressure curve in Mac stylus drivers. That's why we don't have pressure/tilte settings in Mac version of Artstudio.
ah, I was using sidecar, m1 air+ipad air 4+apple pencil
thought it was removed from the trial
anyway pressure kinda works, but would need heavy adjustments since the lines are really faint
krita, for example, offers a pressure curve in the program and works really well
prob will just buy the ipad version
