I have had to postpone my review of Snow Leopard because I intend using it with Final Cut Pro 7 running on a MacPro and ingesting with an AJA io HD. The problem is that AJA as yet running into week 7 do not have the drivers for FCP-7/Snow Leopard.
I do however have Snow Leopard running on two iMacs and it works fine in fact I can tell you that my iMac which is a later model is more responsive but I do not have FCP-7 on this machine so I can’t judge using it in a professional editing environment .
For those of us using the Sonnet Tempo SATA E4P eSATA card and a DP500 Sonnet have posted the following message. “Snow Leopard compatible (32bit). Advanced users note that this card is not yet compatible in full 64-bit boot. Snow Leopard default boots in 32-bit mode, except in an Xserve.”
MacBook Pro users have had problems using Snow Leopard as it seems to affect the Sony SxS drivers.
