I'm on a slightly older version than 10.12. I'm out of this limited support range. The problem is that as soon Apple cuts off older systems by heavy force all of the Mac developers running in circles like lemmings and cut off their projects from the older versions too: feeding right into Apple's policy to deprecate older systems for their own greed.

For comparison… I have zero problems bootstrapping a recent gcc with all bells and whistles on my setup. I probably even could bootstrap it still on my even older G4 Mac with 10.6.

But so called "modern" language compilers like Rust of Go… no luck. There's a slight hope for the gcc rust support someday, I guess.
