One thing I missed in my Mac was a remote controller.  So after some googling, the solution I found fits any Mac with an USB port.
This can even be a good solution for those of you using a Mac Pro, since by default specs does not bring a IR receiver.
Get a Manta TR1 Bundle IR receiver from http://twistedmelon.com/shop/ and buy an original Apple remote. I’ve bought my remote on ebay for 5£ and got the IR + Software for 23£. The perfect match…
