The Retina models do not have an infrared (IR) receiver, so they cannot "see" the Apple Remote Control.
See note 1 in sanjampet's first link ("Some Macs do not include a built-in infrared (IR) receiver. Computers without an IR receiver can instead work with the Remote application for iPad, iPhone, and iPod Touch. Check your Mac's documentation, or look in System Profiler (within the USB section) to see if your Mac includes an IR receiver.").
