Mac Mini for AArch64 Compiler Development

Thanks! I got git installed.

It took me a while to get ssh and its utilities installed. The google 
instructions were wrong, of course. I am baffled why such a basic utility is not 
included by Apple.

I also installed the Mac version of dmd. All of the executables in it promptly 
seg fault. And yes, I also installed Rosetta and verified its installation. I 
have no idea what's going on here.
