Regarding TH2G on Snow Leopard
I have been playing around with a new developer release of Snow Leopard. In some of the notes I notice that Apple has made changes to the areas which would deal with the utilization of a TH2G.
Basically, there are new changed which should come with an upcoming update to Snow Leopard. It should correct the issues some of you have been experiencing with DH2G and TH2G devices.
