osx firewall

[indebetouw]

Does anyone know how to avoid having to allow connections in the osx firewall every time I run MPI hyperion?
I get nthread popups every time
Do you want the application “hyperion_sph_mpi” to accept incoming network connections?
even though in my firewall settings, hyperion_sph_mpi is set to "always allow".
Thank you.

added: I tried turning off the Firewall, but that doesn't seem to work; I also tried the fake-app-signing sheningans here:

without avail; possibly Apple has made things more opaque.
