Hey everyone, I have been having this issue for a few months now thinking it's just a simple bug or updated drivers but it's not working. And yes, I have seen this on the forum a few other times but didn't find a solution - I am on a Mac Book, not a PC. No Windows ink program to interfere like have seen in other solutions posts - No I am not on a tablet. The Cintiq works with touch/pen compatibility but is an extra monitor displaying a regular browser mode. - The tablet registers the pen and activation. It works fine in photo software, or on my regular computer use/navigation - It even registers when I select tools on the board. I can pick select tools, line tools of various kinds, ruler tools etc. Just doesn't register my pen on the board. Regular mouse clicks work fine. I didn't have this problem a few months ago, but now that I want to DM again its making it difficult.
