Hi! Two Macs in the household: a 2010 MacBook Air and a 2007 MacBook Pro. I have an Apple Wireless Keyboard and a Magic Trackpad paired with the Air. Everything's working fine with the Air. Now I'm trying to pair them both with the Pro, so that when the Pro is hooked up to the monitor, it can use the keyboard and trackpad. So I disabled Bluetooth on the Air, enabled it on the Pro, and went to "Set Up Bluetooth Device". And... nothing. Neither the keyboard nor the trackpad shows up, even after pressing keys, clicking the trackpad, etc. What am I missing? How can I pair them with another computer? Various Google results say it should just work... Thanks!
