Goban Extensions
To play go against your computer, against an opponent on your local network, or to automatically score games you need to download and install this free package:
This package contains Pachi and GNU Go, go playing programs, and NNGS, a go server software. They are released under the Free Software Foundation’ s GPL license and therefore could not be directly bundled with Goban on the App Store.

More details
Goban can only execute programs from its scripts folder. Those programs will be sandboxed and will have no access outside of it.
You can find this folder using the menu Goban, Open Extensions Folder…
There, you can install other GTPGO programs, or extra files like overture libraries for Pachi.
