# `CauldronGPU.Setup.MacOS`
[🔗](https://github.com/jaman/cauldron/blob/v0.3.3/cauldron_gpu/lib/cauldron_gpu/setup/mac_os.ex#L1)

Building the renderer on macOS (`CauldronGPU.Setup.Platform`): Apple's command-line tools
for Swift and Metal, `pkg-config` and SDL3 from Homebrew, and, for the Vulkan backend
that runs through MoltenVK, Vulkan's loader and headers.

Looks in `pkg-config`'s own search, Homebrew (`/opt/homebrew`, `/usr/local`), MacPorts
(`/opt/local`) and LunarG's SDK (`~/VulkanSDK/<version>/macOS`). Installs through
Homebrew, and installs Homebrew itself with its official installer when it is missing.
