# Building Zed for macOS
## Repository
Clone down the [Zed repository](https://github.com/zed-industries/zed).
## Dependencies
- Install [Rust](https://www.rust-lang.org/tools/install)
- Install [Xcode](https://apps.apple.com/us/app/xcode/id497799835?mt=12) from the macOS App Store, or from the [Apple Developer](https://developer.apple.com/download/all/) website. Note this requires a developer account.
> Ensure you launch XCode after installing, and install the MacOS components, which is the default option.
- Install [Xcode command line tools](https://developer.apple.com/xcode/resources/)
```sh
xcode-select --install
```
- Ensure that the Xcode command line tools are using your newly installed copy of Xcode:
```sh
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
```
* Install the Rust wasm toolchain:
```sh
rustup target add wasm32-wasi
```
## Backend Dependencies
If you are developing collaborative features of Zed, you'll need to install the dependencies of zed's `collab` server:
- Install [Postgres](https://postgresapp.com)
- Install [Livekit](https://formulae.brew.sh/formula/livekit) and [Foreman](https://formulae.brew.sh/formula/foreman)
```sh
brew install livekit foreman
```
Alternatively, if you have [Docker](https://www.docker.com/) installed you can bring up all the `collab` dependencies using Docker Compose:
```sh
docker compose up -d
```
## Building Zed from Source
Once you have the dependencies installed, you can build Zed using [Cargo](https://doc.rust-lang.org/cargo/).
For a debug build:
```sh
cargo run
```
For a release build:
```sh
cargo run --release
```
And to run the tests:
```sh
cargo test --workspace
```
## Troubleshooting
### Error compiling metal shaders
```sh
error: failed to run custom build command for gpui v0.1.0 (/Users/path/to/zed)`**
xcrun: error: unable to find utility "metal", not a developer tool or in PATH
```
Try `sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer`
### Cargo errors claiming that a dependency is using unstable features
Try `cargo clean` and `cargo build`.
### Error: 'dispatch/dispatch.h' file not found
If you encounter an error similar to:
```sh
src/platform/mac/dispatch.h:1:10: fatal error: 'dispatch/dispatch.h' file not found
Caused by:
process didn't exit successfully
--- stdout
cargo:rustc-link-lib=framework=System
cargo:rerun-if-changed=src/platform/mac/dispatch.h
cargo:rerun-if-env-changed=TARGET
cargo:rerun-if-env-changed=BINDGEN_EXTRA_CLANG_ARGS_aarch64-apple-darwin
cargo:rerun-if-env-changed=BINDGEN_EXTRA_CLANG_ARGS_aarch64_apple_darwin
cargo:rerun-if-env-changed=BINDGEN_EXTRA_CLANG_ARGS
```
This file is part of Xcode. Ensure you have installed the Xcode command line tools and set the correct path:
```sh
xcode-select --install
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
```
Additionally, set the `BINDGEN_EXTRA_CLANG_ARGS` environment variable:
```sh
export BINDGEN_EXTRA_CLANG_ARGS="--sysroot=$(xcrun --show-sdk-path)"
```
Then clean and rebuild the project:
```sh
cargo clean
cargo run
```
