I just bought a macbook pro from a friend, and he has TONS of applications on the mac currently, although its running a bit slow so im thinking about re installing the operating system. A few questions; is there any way to back up the expensive applications he has on it? Such as microsoft works, and adobe cs3? Those are the only applications i need, and i dont want to re install the operating system and lose the applications? Get my flow? Can someone help me answer this? Thanks !!
