I have downloaded it, set the permission bits and everything except the pssetup seems to work alright. I have tried to set loadallmaps=true but end up with the same failure as on the windows version - it freezes when everything is loaded.
It does seem to run a little more laggy then before the update, movements comes sometimes in jerks.
My set up is a G5 2x1.8GHz, 1,5GB RAM, ATI Radeon 9600XT 128MB.
But all in all - it\'s good to have the MAC-version back.
Thanks from the bottom of my heart to DFryer and everybody else which have helped him.
