i was trying to play Halo full game installed and patched (2.0.4) but it wasn't working : it crashed as soon as i launched it.
-> here is the solution i found, thanks to HaloMD application :
you just have to go to /Users/username/library/Application Support/HaloMD/
replace the application HaloMD by your 2.0.4 full version one (Application/Halo) , and rename it "HaloMD" .
launch haloMD app from the HaloMD folder (not the one we were in)
and voilà , works just fine !
hope this can help to those who are nostalgic of the campaign and full game multiplayer , such as me
