Well, any steps I can issue on the command line should be translatable into a recipe.

The problem with it is the host-recipes aren’t OSX-friendly. They are all linux-specific. Yocto itself can be made to run  on OSX with a few minor patches and putting certain gnu tools place of OSX tools (sed comes to mind). Once you have that Yocto would be able to drive your toolchain the same way it does on Linux.

Why? Why would anyone do that?
