# Build Instructions (macOS)
Follow the guidelines below for building Electron on macOS.
## Prerequisites
* macOS >= 10.8
* [Xcode](https://developer.apple.com/technologies/tools/) >= 5.1
* [node.js](http://nodejs.org) (external)
If you are using the Python downloaded by Homebrew, you also need to install
following python modules:
* pyobjc
## Getting the Code
```bash
$ git clone https://github.com/electron/electron.git
```
## Bootstrapping
The bootstrap script will download all necessary build dependencies and create
the build project files. Notice that we're using [ninja](https://ninja-build.org/)
to build Electron so there is no Xcode project generated.
```bash
$ cd electron
$ ./script/bootstrap.py -v
```
## Building
Build both `Release` and `Debug` targets:
```bash
$ ./script/build.py
```
You can also only build the `Debug` target:
```bash
$ ./script/build.py -c D
```
After building is done, you can find `Electron.app` under `out/D`.
## 32bit Support
Electron can only be built for a 64bit target on macOS and there is no plan to
support 32bit macOS in the future.
## Tests
Test your changes conform to the project coding style using:
```bash
$ ./script/cpplint.py
```
Test functionality using:
```bash
$ ./script/test.py
```
