As in MapKit, a two-finger tap should be interpreted as a secondary click to open the context menu, if applicable. It should not zoom out; rather, a double-tap on a mouse should zoom out (“smart magnification”).
Mapbox OS X SDK
A library based on Mapbox GL Native for embedding interactive map views with scalable, customizable vector maps into Cocoa applications on OS X 10.10.0 and above using Objective-C, Swift, or Interface Builder.
This SDK is analogous to the Mapbox iOS SDK, and much of the iOS SDK documentation applies here. Mapbox does not officially support the OS X SDK to the same extent as the iOS SDK; however, bug reports and pull requests are certainly welcome.
