A backgrounder for this instruction (you can read it only if you are interested)
Worksnaps Client for MAC depends the accessibility to get the keyboard events, so we need to enable accessibility on Mac OS. Prior to Mac OSX 10.9 (Mavericks), Worksnaps client can enable the accessibility programmatically. However in OSX 10.9 and 10.10 there is no such API to programmatically enable accessibility from the application. Therefore, users have to enable it manually.
With Mac OSX 10.9 (and subsequently in 10.10), Apple has moved accessibility option to System Preferences > Security & Privacy > Privacy. Unlike previous versions of Mac OSX, which use a universal check-box for all applications, the new functionality in 10.9 and 10.10 lets users to individually choose which application can gain control of the system to perform their various scripted functions.
