Sometimes when you are around many Mac users and everyone has a remote, say during presentations it can be annoying to have others remote controls messing with your Mac. Or in the case of a kiosk computer, you don’t ever want a remote control to function.
To disable or block all remote controls from accessing your mac, click on the System Preferences icon. From the System Preferences screen click on Security.
From the Security settings window check the box next to Disable remote control infrared receiver.
That’s all there is to it. No remote control will now be able to work with your Mac (regardless of pairing).
