You'll need to download and install the following to build Citra:
* [CMake](https://cmake.org/) (`brew install cmake`)
* [Qt5](https://www.qt.io/download/) (`brew install qt5`) (**Note:** If you have Qt4 installed, then you will need to remove it before building. `brew unlink qt4`)
* [Python 3](https://www.python.org/) (`brew install python3`)
* The version included with the default developer tools may run into an issue downloading Qt.
* A recent version of Xcode and the Xcode command line tools
* **Optional dependencies**:
* [FFmpeg](https://www.ffmpeg.org/download.html#build-mac) 4.0+ is needed for HLE AAC Decoding on macOS (`brew install ffmpeg`)

### Using CMake:
First of all, you have to tell CMake where your Qt5 is installed (add this line to ~/.profile if you want to make this permanent.):
```
export Qt5_DIR=$(brew --prefix)/opt/qt5
```
Now you can generate makefiles for the build:
Create a build folder and generate makefiles for the build:
```
mkdir build
cd build
cmake .. -DCMAKE_OSX_ARCHITECTURES="x86_64;x86_64h" -DCMAKE_BUILD_TYPE=Release
```
* To enable HLE AAC Decoding, include the cmake flag `-DENABLE_FFMPEG_AUDIO_DECODER=ON` (make sure FFmpeg is installed first.)

A `citra-qt.app` application bundle will now be present under `build/bin/`. Note that this is non-portable and only works on your machine.
For portability of the appbundle between machines please refer to [this script](https://github.com/citra-emu/citra/blob/master/.ci/macos/upload.sh).

### About building on Apple Silicon machines
To build Citra targetting MacOS on ARM, the process is largely the same.

A few things to note are:
* Make sure the Homebrew version you have installed is the ARM version
* When running the cmake command, you'll want to use this command instead:
* If you are cross-compiling, when running the cmake command you'll want to use this command instead:
```

You can similarly enable HLE AAC decoding by appending the flag `-DENABLE_FFMPEG_AUDIO_DECODER=ON` to the cmake command.
