I know this is a particularly specific question, but as an illustrator I don't want to upgrade to El Cap until I have a good sense of whether or not my drawing setup will work as usual. I'm using Photoshop CS6 with a Wacom Intuos tablet for my stylus input (currently on my 2011 MBP running Yosemite and working great). Anyone out there using a similar setup? If so, any issues I should be aware of?
