Hey all. When I purchased this machine, 2.2ghz i7, 4gb ddr3 etc, it ran great for ally my uses, games, digital design, etc. Now, using Safari and listening to iTunes impossible. I'm updated to current software, I'm running Snow Leopard. I've used Onyx for maintenance, Memory clean, with no luck. This machine is running like a dog. Constant freezes... What can I do to solve this? Are there any other maintenance I can run to clean things up? It's getting to the point where I just want to sell the machine and get something new. Thanks.
