Illustrator pressure sensitivity grayed out
I have a Yiynova MVP 22U and I am tying to get pressure sensitivity to work in adobe illustrator CS5. I Have a Mac 10.12.6 operating system. The pressure sensitivity works in Photoshop, Clip Studio Paint, and Sketch Book Pro. I've tried uninstalling and reinstalling with no results. I also tried installing a Wacom Driver too but that just made all tablet functions not work.
