Please share the complete patch, so that developers can test. It might
be better than the one I sent.

Please report the errors and share the patches, either here or at
    https://github.com/OpenGATE/Gate/issues
I guess you are using 10.9/10.10?

Someone else will have to answer that. My first guess would be that
the code is not as widely tested as the rest of Gate, so there might
be some trivial compiler-related issues (something that works with one
compiler and not with the other / in other OS). I have never tried to
enable GPU code so far.

It took me quite a while to get all major compiler errors and bugs
fixed and to come to a state where Gate.app became usable (and even
then I just learned about new issues yesterday), but now that we have
it under MacPorts, repeating the same steps under HomeBrew shouldn't
be a big deal. I see that both Geant4 and ROOT 5 formulas are already
there.

The MacPorts port also does a few special things in the Qt app (some
sugars for the user) that could/should probably be included upstream
into Gate and thus made available on all platforms.
