Well, I'm running it on an OctoCore 3.0Ghx model...2008...and it's not quite as snappy as it should be. Running it on my brand new 2012 MacBook Pro and it is much more responsive. I thought it was my Kona card, but I uninstalled the drivers for that and it made little difference. I get beachballs on occasion, but the big issue is it takes a while to autosave, and I will have moments where I do 8 keystokes, and then need to wait for the Avid to catch up to me. That doesn't happen on my laptop.
MC6 is 64 bit, and to enable those abilities, you need a qualified machine. Your's isn't so you won't see any benefit...in fact, it'll be slower than previous versions. Stick to a version that works great on your machine, or get a new machine that will work with MC6. Heck, I know places still using MC4...MC3...MERIDIANS! But MC4 is more common among the older models. Keeping up with software advances means doing the same with hardware.
"Mac Pronicorn"...love it.
