Art Programs/Set Ups for Mac? (Calling Artists!!)

I've been really wanting to get back into digital art and practice again, and maybe try and sell some art here and there! But in current living arrangements, I only have access to an older Macbook I received when they decommissioned it from school a few years ago, and of course my trusty old Wacom Intuos- but I'm unsure what programs work best with Mac/are easiest to use with the system.

I haven't been active with my digital art in years, but the last program I really used was PaintTool SAI. I'm kinda hoping maybe in the years I've been away, there's some newer program people are using more frequently, because I wasn't really a huge fan of SAI.

Artists on Mac OS-... What programs/devices do you use most frequently? 

i moved from photoshop to paint tool SAI because photoshop felt a bit clunky in comparison and i had access to windows. but then! i moved to clip studio paint! and that has been an absolutely fantastic experience. the brushes that come with it are super good already, there's a 3d modeling function that i've never used but i've heard is great for painting over, it has comic templates if you're into that, and it very frequently goes on sale. one of the best art programs i've ever used.
