Can't you just install dtc or libfdt with homebrew? And then just include the generic path to the headers and libs?

Hey @apritzel. I think so, didn't know there was a brew install dtc.

@apritzel I didn't have a Mac to test but now I do, looks like you can definitely include the generic path to headers and libs from homebrew :) sunxi-tools-macos.patch

I'll leave my patch here in case anybody needs it. Just brew install dtc, apply this patch and then make. Not perfect tho, but it works.
