u need to run bootcamp on the mac which in turns runs xp or vistas for metatrader. I would not recommend parallels (where you can run apple os and microsoft at same time). run the bootcamp and switch back to apple os when you want mac features. I have both macs and sonyvaio/dells...I like the mac just don't like the fact forex
trading platforms are built for microsoft os. hope this helps. by the way, XP works GREAT on the mac.
