Tomorrow I'm supposedly receiving my first Mac, a MacBook Pro with Retina Display. I have a dilemma my current system is an antiquated Dell PC desktop. I got Dell Speakers with Dell Subwoofer which unlike the computer still works and the sound is rather good. Can I use them with the MacBook Pro. The cord looks like it would go in the headphone port on the MacBook. But I'm not sure if it is compatible. Also Not sure if i want to combine and use a Dell product with a Mac. Perhaps i should go get new speakers? Also, the subwoofer takes up space which I was looking forward to gaining on my desk by using a MacBook and not a huge desktop PC. Any suggestions?
