Sorry, there's a lot of macOS-specific dependancies.

Pull Requests welcome.

@aharpervc, great idea! We absolutely want to support Windows, but didn't get around to it before shipping this first version. There are two main places where we rely on macOS APIs: screen recording and simulating mouse movement. We plan on eventually supporting Windows, but of course, we're happy to facilitate working on this if there's a strong demand for it earlier.
