Specifically OSX 10.5.8? The gog version is for intel macs.

Which Duke, but it runs in DOSBox or Boxer for Mac version no? dmg (Universal)

Then copy the files out of the .dmg.

You are correct. I didn't specify which game. I'm playing the demo of Duke 3D which runs on my PPC using OSX 10.58 (Leopard). I just wanted to know if I can find the full version that will run on my machine. I know nothing about DOSboxing or whatever it was in your reply. It's way over my head.

For PPC? Not that I know of. GOG version is packaged with newer version of Boxer, technically Boxer Standalone, which is Intel only. Some of the older versions supported PPC, but I'm not sure if the .boxer archive from the newer versions are compatible or not. If you had a working older Boxer & they were compatible then it's simple enough to copy the Duke Nukem 3D.boxer out of the GOG version.

Thanks for the information. I don't know what a boxer is. I'm not well versed in how the mac works except that it's different than a Windows machine (about which I really know nothing). I use my G5 tower to run my recording apps and play an occasional game and was having fun with the Duke demo and looked around the web for the full version coming upon gog.com. I'm not getting an intel machine in the near future. But thanks anyway.

Boxer. Like I said before, he dropped PPC support in the more recent versions.
