You need to have one device act as a central (which you do) and one as a peripheral device. So assuming that you use your MB Air as the central, you need to start a CBPeripheralManager on your iPad and have it publish and advertise a service. Then you should be able to discover it on your MB.
I guess the easiest way would be to get a working peripheral (e.g. a heart rate belt), so you can familiarize yourself with the usage of CBCentralManager. Then you could start implementing your own peripheral.
PS: I am not sure it is correct to put 0x
at the beginning of the identifier.
