If you are on a newer Mac you can not use the older versions of the sdk, so try the newest SDK.

Now, I downloaded the mesasdk-x86_64-macos-20.11.1.pkg and when I try to install it…the installation does not work saying me: "installer encountered an error that prevented installation. Contact the software manufacturer for assistance.” I have install/unistall it a couple of time but now I have a this new problem.  So you can imagine that neither the mesa installation works.
