The Mac version is very potent as is but not very friendly when it comes to adaptation to ones personal workflow. But to keep up with the competition on the iPad I guess Lucky Clan have to pour all of their effort into the mobile version. We still get the engine upgrades with its bells and whistles.
If you have Apple silicon M1/M2 you can run the iPad version in MacOS. Keyboard shortcuts exists if you don't have a touch enabled tablet. There are some drawbacks. Personally I have to drag my images in to the app from finder as I can't find any gallery or file browser. The mouse cursor doesn't disappear when the brush is over the canvas.
This can be cured by installing the tool Cursorcerer. The app Mousecape can help to make a custom cursor, like a black dot with white outline, to be less intrusive when painting.
Sidecar, Easycanvas and Astropad acts a bit weird when using touch. Astropad have a nice option to hide cursor when painting. I don't think Apple had painting apps in mind when creating the framework for running iOS/iPadOS apps in MacOS.
I still prefer the desktop version on my Mac though.
