If you install all of the GNU tools using brew or similar and put them
first on $PATH then you can get bitbake started.  Then you need to stub out
the linux-specific bits in bitbake.  I've previously started on this work
already (
http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=ross/darwin).
The next step is figuring out how to configure OE to build and link
natively on OSX using LLVM instead of GCC.

However all of this is mostly academic because in Sierra (iirc) onwards
there is tighter security on processes, which means that pseudo won't work
even if you port it to macOS.

So unless you fancy some non-trivial engineering the short version is just
use something like Docker to run a Linux system on your Mac.
