Hello. I don't have much knowledge Macs but I do need to finally upgrade from Tiger to Snow Leopard video and photo editing purposes. My 1st generation Intel mac pro desktop 4-core has 6G of Ram and plenty of hard drive space as I edit HD video footage. My question is will any full version of Snow Leopard (not a recovery DVD) install properly? All the threads and questions that I see out there seem to all be for Macbook Pros. I have an old version of Final Cut Studio 2 which is fine for me at this time but I wasn't sure if it would be compatible with Snow Leopard. Also, is it worth it for me to keep upgrading my system or should I be looking at getting a new Mac? Any help will be greatly appreciated. Thanks for reading!
