At the time of writing there are no CoolProp binary wrapper downloads for Mathematica beyond CoolProp 5.1.1, and they won't library load in Mathematica13 on and M1 Max machine.
If you attempt to compile the nightly build (as of 2022-06-27) with the Mathematica module included using DCOOLPROP_MATHEMATICA_MODULE=ON, you'll find that it will report an error about Darwin not being supported, because it has an old FindMathematica module from about 2018.
The fix was kindly provided by CoolProp contributor Jeff Henning at this CoolProp issue posting. Just download the latest FindMathematica version and replace the .../externals/FindMathematica
from the CoolProp nightly build with the newer one (if you download the ZIP you'll need to rename it from FindMathematica-master
to FindMathematica
. It will then build okay and the libCoolProp.dylib
will load and run fine in Mathematica.
