I was recommending this way in our recent workshops because it's the
only way which works with SIP enabled. It's far from ideal because it
doesn't always work, sometimes people have several Python
installations on Mac which complicates things and for some reason,
ctypes don't work there (so no PyGRASS or digitizer or 3D view). And
the installation takes time on slower computers because it's compiling
everything.

Michael's binaries work only when SIP is disabled. It's fairly easy to
disable it, but still, you have to boot into recovery system, open
command line and run a command there, so it looks little scary for
most people.

Even your own compilation is fairly difficult, one reason is that
official wxPython 3 mac package is old and new macs refuse to open and
install. So in general I am getting sick of this issue and
unfortunately I don't have time nor knowledge to do anything about it.

this is something I haven't even tried. If some of your students find
better ways of installing GRASS, let me know.
