Accessibility and security: You might rely on apps that leverage OS X's built-in Accessibility technologies and not even know it. Apps such as Smile's TextExpander and Many Tricks's Moom and Witch all rely on Accessibility settings on your Mac. The preference to allow apps to access these features has moved in Mavericks. To find Accessibility, go to System Preferences > Security & Privacy and click the Privacy tab. (You may need to click the lock icon at the lower left and authenticate with your administrator password.) Then scroll down to Accessibility, and drag into the list any apps to which you'd like to grant such permission; if an app has explicitly requested such access, it will already appear here.
