Personal notes building zig 0.15.0-dev.xxxx on Macbook M3 Max
20250731 Sequoia 15.6, latest XCode Commandline Tools, homebrew-installed LLVM 20.1.8 (llvm@20)
This way of building probably works on all Apple Silicon Macs, but you must check other models yourself. I keep a list of some successful M3 Max builds here
Some Intel Macs should also work (default homebrew path is the only significant difference). But I don't test that anymore.
