# Portal 2: static recompilation for Apple silicon

> Portal 2 is statically recompiled from its Linux x86 modules into a native ARM64 application for macOS and iPhone. Preparation tools lay out ELF modules and apply relocations; a lifter emits C functions that are compiled with a runtime for libc, threading, SDL2, graphics and Steam interfaces. The author reports playable builds on Mac and iPhone.
