Adding support for macOS 10.12

[hurricanehrndz]

Nix uses a relatively old SDK for mac. Just wondering if it would be possible to add support?

Where is macos 10.12 not supported?

I have yet to get a successful build... I know this is out of scope, since ideally macOS 10.13 and above should only be supported. Any help though would be appreciated. PS I am a novice when it comes to C++ compiles.

This leads to the following error:

check is obviously defined using functional template on line 1450. So I am at a lost.

I think this is not supported by your compiler.
