I'm little confused because the Apple Store offers me an Apple Remote when I try buying a new MacBook Pro, but I don't see any information about support for that remote in the MacBook Pro's description.
From the Manual for the 13inch, here is a picture that shows you where the IR port is located.
Yes it does support it. You can verify this information because when you go to the apple store and select a new model, one of the accesories you can add to your purchase is the apple remote. They wouldn't add that if you couldn't use it :)
I assume the IrDA port is there @ the front of the machine, possible hard to see in the official pictures.
