Is there a version for Mac OS?

I have just got an iBook and don't know if I need to install linux on it to use it with my vdr-server.

On the other laptop we use ubuntu with vdr-sxfe and a remote control sender to watch tv in another room. However, it's a slow pc and I want to know if this iBook is good enough (it's a G3 700mhz - so not an Intel thing..)
