If you are using Mac OSX 10.9, 10.10, 10.11, 10.12, 10.13, 10.14, please follow the instructions below to enable accessibility, otherwise, the Worksnaps client can't capture keyword event, it can capture mouse event only.
If you are using Max OSX 10.15 (Catalina), please refer to this document.

If you do not see it now, you might need to wait for the system to prompt you when Worksnaps Client tries to take a screen shot. In such case, please refer to this help document.

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.
