Is there a version for OSX El Capitan?
The application is said to be compatible with Mac OSX 10.7+ which means El Capitan should be included as a compatible version as well. However, the best way to test it is by downloading the available package.

Save the DMG package and then initiate the normal installation procedure. In case you have issues with it, report the problem to the developers: http://www.linear.com/contact/
