I am the developer of an app called 1Keyboard (http://www.eyalw.com/1keyboard).
my app used to capture global keystrokes and send them to iPhones/iPads/etc as if the computer was an HID bluetooth keyboard.
This worked on 10.8, and dais on 10.9. I understand it has to do with the new Accessibility menu in system preferences. Instead of having one checkbox ("enable assistive devices") in 10.8, now the user has to enable this for each app individually.
For some reason, my app doesn't show up in the accessibility requiring apps in the preference. http://d.pr/i/8IfP
What should I do to have it appear there, and restore the lost functionality?
