:warning: We do not yet officially support MacOS 13. But, as long as you are not using a zig or wasm platform most things should work fine.
:warning: Macos x86_64 nightly releases lag behind the others due to [unresolved test failures](https://github.com/roc-lang/roc/issues/4655). The `dbg` keyword is not yet supported, as well as importing platforms using URLs. For the platform you can use the path instead, like in [this example](https://github.com/roc-lang/roc/blob/main/examples/helloWorld.roc).
This step is not necessary if you only want to use the [basic-cli platform](https://github.com/roc-lang/basic-cli), like in the tutorial.
But, if you want to compile Roc apps with other platforms (either in [`examples/`](https://github.com/roc-lang/roc/tree/main/examples) or in your own projects),
you'll need to install one or more of these platform languages too.
1. If you'd like to use Zig-based platforms: download [zig 0.9.1](https://ziglang.org/download/0.9.1/zig-macos-x86_64-0.9.1.tar.xz), extract the archive and add `export PATH=$PATH:~/path/to/zig` to your shell startup script (.profile, .zshrc, …). Note: zig 0.9.1 is not available on homebrew.
