• Please make sure you have the latest version of Remote Buddy installed. If in doubt, download the latest version, quit Remote Buddy, delete it, empty your trash, then copy the downloaded version of Remote Buddy to your harddrive and start it from there.
• Please make sure, that you have installed the latest version of the Remote Buddy drivers. You can install the drivers using the Setup Wizard (=> access it via the Remote Buddy pulldown menu).
• Check your Remote Buddy settings in the Hardware category. Your remote control should be listed there and the lamp next to it should be green. If you don't find your remote control there, either the Remote Buddy drivers were not installed or installed in an outdated version - or - there is a general problem with the device. For USB devices, plugging the device to another port or resetting the PMU and/or SMC-unit of your Mac (=> find guides on how to do this for your Mac in the support area of apple.com) may help. If you can't find it under "USB" in the System Profiler (=> /Applications/Utilities) either, a hardware defect is as well possible.
• Check the batteries of your remote control.
• If your remote control has an on/off switch: make sure that your remote control is switched on.
• If your remote control requires additional receiver hardware: make sure that it is correctly attached to your computer and that it turns up in System Profiler.
• If you use an Apple Remote, you should also check your system settings. Quit Remote Buddy, then open System Preferences.app > Security. Please make sure that the option to disable the infrared receiver is NOT active and click on "Unpair" should you have paired your Apple Remote with your Mac. After that, start Remote Buddy. If your Apple Remote still doesn't work with Remote Buddy, please also check its preferences for the Apple Remote. They can be found at Preferences > Hardware > Built-in IR receiver. If support for multiple remote controls is enabled there, ensure that your remote control is checked in the right table (=> you can find the correct entry for your remote control by pressing a button on it).
• If you are using a Keyspan RF Remote for Front Row, re-pair its remote control and receiver by simultaneously pressing the small knob on the back of the remote control and the knob on the receiver stick (the knob looks like the blinking LED, except it does not blink).
