platform-osx now vends a real NSView subclass, MGLMapView, that is readily embedded inside a Cocoa application for OS X. MGLMapView is backed by an NSOpenGLLayer for optimal performance and integration with other layer-backed views. It supports keyboard shortcuts and several gestures and hosts attribution, zooming, and rotation controls as subviews. osxapp is now a bona fide Cocoa application that embeds MGLMapView inside a XIB. osxapp has preferences and a share button for tight integration with custom styles. Enabling asynchronous rendering would be more consistent with iOS but increases CPU usage so much, even when idle, that it isn’t worth any performance gain. The bigger issue is that VAOs aren’t being used. make xpackage creates a static library similar to the one created by make ipackage. make clean cleans additional places where build output ends up. The OS X minimum deployment target has been increased from 10.9 to 10.10. osxapp’s window has a full size content view, which requires 10.10. Lightweight generics require iOS 9+ and OS X 10.11 regardless, because it was only in that release that Foundation collection classes started adopting lightweight generics. Shuffled files around and refactored annotations so that iOS and OS X share a good chunk of the annotations code, which now takes advantage of polymorphism. MGLMapView can now display annotations but cannot yet select them. In osxapp, a long press drops a pin, and so does the map view’s context menu. Annotations have NSPopovers as callouts, and their view controllers can be customized. Annotation image alignment rects are respected for hit testing purposes and for positioning the callout anchor. Callouts in osxapp demonstrate the use of bindings to keep callouts in sync with underlying model objects.

Developing on OS X
To create projects, you can run:
make xproj: Creates an Xcode project with a native OS X application for testing changes to mapbox-gl-native on the desktop.make lproj: Creates an Xcode project with platform-independent handlers for downloads and settings storage. This is what is also being built on Linux.make osx run-osx: Builds and runs the OS X application on the command line withxcodebuild.
Note that you can't have more than one project in Xcode open at a time because the static library project is shared across the OS X, Linux and iOS project.
Access Tokens
The demo applications use Mapbox vector tiles, which require a Mapbox account and API access token. Obtain an access token on the Mapbox account page. You will be prompted for this access token the first time you launch the demo application.
Usage
Through the OS X SDK, the demo application supports a variety of standard gestures and keyboard shortcuts. For more details, open Mapbox GL Help from the Help menu.
