I only have a 10.8 system (64 Bit) here but the 10.8 and the 10.9
version are the same ones. I assume he is using the pre-built version
available at the gnubg.org website? (As well what version of GNUGB is he
using). If he built his own the location will be different. Before I
emailed you my original answer I used the makehyper program to generate
the files and I moved them to that exact directory and they were found -
and the About page verified they were loaded.

I can only think his files are corrupt or not named correctly. They do
need to be named hyper1.bd, hyper2.bd, and hyper3.bd . Any other names
and they will not work. Did he genrate his own or download them. If he
downloaded them where did he get them from?

I am thinking there is something they are missing and likely not a bug.

Yep, they load on my Win7 system as would be expected.

I don;t now of any, but if someone created one we could integrate it
into GNUBG. Probably have to change the GUI so that we can explicitly
set a Hypergammon only MET. It would be used if someone starts a
Hypergammon match. At present you would have to manually change the MET
before a match.
