## macOS
To compile Cemu, a recent enough compiler and STL with C++20 support is required! LLVM 13 and
below, built in LLVM, and Xcode LLVM don't support the C++20 feature set required. The OpenGL graphics
API isn't support on macOS, Vulkan must be used. Additionally Vulkan must be used through the
Molten-VK compatibility layer
lower don't support the C++20 feature set required. Cemu doesn't support using OpenGL
on macOS, Vulkan must be used via the Molten-Vk compatibility layer.
### On Apple Silicon Macs, Rosetta 2 and the x86_64 version of Homebrew must be used
You can skip this section if you have an Intel Mac. Every time you compile, you need to perform steps 2.
1. `softwareupdate --install-rosetta` # Install Rosetta 2 if you don't have it. This only has to be done once
2. `arch -x86_64 zsh` # run an x64 shell
Note that if you are compiling on/for Intel, you must replace all references of `/opt/homebrew` to `/usr/local`.
### Installing brew
1. `/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"`
2. `eval "$(/usr/local/Homebrew/bin/brew shellenv)"` # set x86_64 brew env
3. `eval "$(/opt/homebrew/bin/brew shellenv)"` # set brew env

### Build Cemu using CMake and Clang
1. `git clone --recursive https://github.com/cemu-project/Cemu`
2. `cd Cemu`
3. `cmake -S . -B build -DCMAKE_BUILD_TYPE=release -DCMAKE_C_COMPILER=/usr/local/opt/llvm/bin/clang -DCMAKE_CXX_COMPILER=/usr/local/opt/llvm/bin/clang++ -G Ninja`
3. `cmake -S . -B build -DCMAKE_BUILD_TYPE=release -DCMAKE_C_COMPILER=/opt/homebrew/opt/llvm/bin/clang -DCMAKE_CXX_COMPILER=/opt/homebrew/opt/llvm/bin/clang++ -G Ninja`
4. `cmake --build build`
5. You should now have a Cemu executable file in the /bin folder, which you can run using `./bin/Cemu_release`.
#### Troubleshooting steps
- If step 3 gives you an error about not being able to find ninja, try appending `-DCMAKE_MAKE_PROGRAM=/usr/local/bin/ninja` to the command and running it again.
- If step 3 gives you an error about not being able to find ninja, try appending `-DCMAKE_MAKE_PROGRAM=/opt/homebrew/bin/ninja` to the command and running it again.
## Updating Cemu and source code
1. To update your Cemu local repository, use the command `git pull --recurse-submodules` (run this command on the Cemu root).
