XGBoost Broken for Mac Mojave and earlier - Initialization Error

General Usage
18

Ok, it turned out XGBoost does require 10.15, but the good news is that it was unintentional and the fix was very simple.

New build of XGBoost_jll (v1.6.1+1) includes the fix, and it should work on all macOS systems supported by Julia (>= 10.10).

Thanks a lot @hcho3 for the quick help!
