# OpenCE-macOS: porting Halo: Combat Evolved to Apple silicon

> OpenCE-macOS ports OpenCE's Halo: Combat Evolved decompilation to Apple silicon Macs. It builds a native macOS app, maps the game's 32-bit code into a 4 GB address window, and renders through ANGLE on Metal. At first launch, the app imports maps from the user's Xbox disc image.
