ISSUE
Dota2 "Universal Access" is turned on Mac and yet in game still prompt up the message to turn on "Universal Access". I can no longer purchase items, add friend, open up tab to chat under steam window.

OS
Mac OS Yosemite

STEPS & RESULTS
Turned on via "System Preferences" -> "Security & Privacy" -> "Privacy(tab)" -> "Accessibility" -> "Steam(Checked)"

Error when right click on friend list and "Accept friend request".

Screenshot of Error pops up in game:-

EXPECTED
We should be able to add friends in game and purchase items or even open the tab window to chat with friends under "Mac OS".

Please rectify the above. Thank you.


PS:- Posted at Steam Community on this as well. As I'm having difficulty to even purchase a battle pass with this issue around. :/ Very inconvenient.
