Candelair is an alternative driver for the built-in IR receiver as found in many Mac's today. It provides a clean, global fix for Apple Remote issues many users are experiencing with third party applications under Snow Leopard releases 10.6 and 10.6.1. It's based on Remote Buddy's driver and comes packaged in a preference pane that presents all remote control options at a glance. Candelair is a free download.
Note: Now requires OS X 10.6 or later.
