Go to the Avid website and find out what the hardware requirements are.
Plenty of people still use Avid on a Mac, but you’ll find development lags behind the PC. That’s because Apple kicked Avid to the curb after years of Avid being exclusively (for the most part) Mac-centric. Apple wanted to develop this new fangled program called ‘Final Cut Pro’. I don’t think it’ll go anywhere, but hey – I think this thing called the internet is just a flash in the pan. Anybody got a rotary phone they want to sell?
Anyway, if you are going to buy an Avid, do yourself a favor and get a CERTIFIED SYSTEM from a reseller. You will have many people tell you on many boards “bah – I built my own system from paper clips and gum, and it works great!” If your computer skills are VERY good, go for it. I myself have better things to do other than spend my days immersed in the vaugaries of PC/Mac OS. Avid is VERY picky about what it has inserted into it’s slots. Adding Mojo complicates that exponentially. The cost is a little more, but you have somewhere to turn when something goes awry. You are, after all, making money (and I assume a living) off of this machine. If you truly cannot afford a system from a reseller, AT LEAST buy certified components for your system.
Otherwise, make sure you buy a good sturdy hammer. You’ll want it to inflict pain upon yourself when you can’t get your PC/Mac to play nice with Avid and you have a paying customer waiting for a product…
If on the other hand this is a hobby, maybe it will be a good learning experience.
