I'm having a lot of trouble with Illustrator. I'm currently using a MacBook Pro (2016, macOS Sierra), iPad Pro 12.9 fully updated, Illustrator CC 2017 and Astropad Studio 1.0.1, but this has been an ongoing struggle with various older versions as well.
The problem is that I need pressure sensitivity for various tools - Blob Brush, Eraser, Brush Tool, but all stylus related options are grayed out (I can only choose "fixed" - all other options are grayed out).
I have read that this issue can be resolved by installing a Wacom driver on the Mac, but this has not resolved the issue for me. I have tried the latest version, as well a collection of older version drivers - nothing seems to help. I have even gone as far as rebuilding the Mac from scratch. It worked correctly for a couple days after that, and then the options grayed out again.
Any help would be very much appreciated.
