In OSX Catailna Apple have introduced lots of security ‘Features’ which make it harder to install and run software, especially with software that interacts with other applications. You may get a warning telling you that accessibility needs to be enabled.  Here is how you can turn it on for a particular application.

1. This is what the warning looks like:

2. Go into System Preferences and then select Security and Privacy and click on the padlock in the bottom left to make changes.

Now click on the heading called “Accessibility” and tick the radio buttons for the applications that you trust.

Here you can see me turning on accessibility for ‘Dragon’ to allow speech recognition and ‘Jumpcut’ which is a toolbar utility to help with copying and pasting.
