-The easy way is to get the prebuilt dependences from [GitHub Actions][1]. Pick the latest release and download all of the `Sysroot-macos-*` artifacts. You need to be logged in to GitHub to download artifacts. If you only intend to run locally, it is alright to just download the sysroot for your architecture.

+- Pick the latest release and download all of the `Sysroot-macos-*` artifacts for the architecture you will need (you will need to be signed in to a github account). If you only intend to run locally, it is alright to just download the sysroot for your traget architecture.
+- Unpack them into the UTM project folder. You should have a "folder" configured per architecture (see screenshot for an example)

 If you want to build the dependencies yourself, it is highly recommended that you start with a fresh macOS VM. This is because some of the dependencies attempt to use `/usr/local/lib` even though the architecture does not match. Certain installed packages like `libusb`, `gawk`, and `cmake` will break the build.
