Bug installing Mac OSX on Catalina

[adam2392]

Describe the bug I run through the installation instructions for MACOSX and I get this bug:

(base) adam2392@Adams-MBP-3 packedForest % make
g++ -std=c++11 -fopenmp -Wall -O3 -ffast-math -Iinc -I/usr/local/include -I/usr/local/include/eigen3 -c -o obj/fp.o src/fp.cpp
clang: error: unsupported option '-fopenmp'
make: *** [obj/fp.o] Error 1

Expected behavior Wasn't sure if this has been seen before, or what are the best work-arounds. I don't have access to my Ubuntu workstation since I can't get on JHU campus :p.

Desktop (please complete the following information):

• OS: macOS Catalina
