Hi Chris,
HydroHub can be opened on my new Mac now. It works fine when visualizing data in NetCDF files. One issue is that, when I tried to run an AEM3D simulation with the executables generated from my old Mac (Intel CPU), it reported an error saying libiomp5.dylib is missing. This file seems to be related to the ifort compiler in the old Mac.
Cheers.
Wencai
