I upgraded to Leopard and have not been able to use my remote with Logic Studio like I had previously used in Tiger. The remote also does not work in Garage band. I spoke with apple support at both the apple store in Westchester, NY and on the phone and both were not able to give a answer if it was a bug or if it could be fixed. Most of the time Apple genius's google to find the answer to a problem. I could do this at home and it is defiantly preventing me from purchasing Apple extended warranty. I am just about ready to downgrade to Tiger since my MBP is new and has barely anything on it. I do hope Apple gets back in the game with customer service. They really use to be great and knowledgeable.
