I am running h25 on my dual2.0 G5 (bought from HES 2.5 years ago). I am currently running 10.3.8 which is recommended on the blackmagic design page for the decklink extreme.

I'm not at all knowledgable on the Mac. Is 10.3.8 that much different than 10.3.9 that you wouldn't recommend it? My system hasn't shown any real problems recently, but I also don't push it that hard.

Thanks.
