lock remote to your Mac Book Pro
Guess you have two Mac Book Pro’s and a remote then you will find that both will act to the remote at the same time. But if you turn on one mac and then hold the Menu and the fast forward button pressed till you see a chain logo appear above a remote then the mac will only respond to this remote.
Very handy when you have two macs and remotes.
You can unpair the mac going to the security tap and then unpair.
