My objective here is to create a connection between a device running iOS to a device running Mac OS X, via bluetooth. I know that I might be able to use CoreBluetooth for this but I don't understand how since I don't see a method to setup a service on the iOS device and broadcast it as an available service for a device running Mac OS X. In other words, I simply want to setup a connection to get the iOS device to send data to the Mac OS X device. Also, how would I go about to specify how to setup properties of the service. I've tried researching this stuff but most of the documentation makes little sense to me. The data transfer is small so bluetooth is good enough for the job. I'm trying to avoid Bonjour for this, and the Game center framework for P2P since OS X can't handle that (I think).
In iOS6 the iPhone 4S, 5 and New iPad can work both as Peripheral and as Central in Bluetooth Smart / Low Energy mode. Try downloading "LightBlue" APP from APP Store. It let's you put the iPhone4S or 5 into Peripheral mode with random Services which you can then read from the Mac (if you have a newer one with BT Low Energy, I use the Retina for that but also the new iMac and Mac Mini got BT Low Energy).
You are correct that Core Bluetooth only give access to Bluetooth Low Energy which doesn't allow for the MFI chip.
Just ran across this today... and just wanted to give another answer to anyone needing to communicate to a non-Bluetooth LE device from your Mac.
The way to go is with IOBluetooth, and IOBluetoothUI. They are both frameworks for the Mac, and they allow you to communicate with both old bluetooth, and Bluetooth LE 4.0, I believe. Also, I'm pretty positive you can act as a Central and Peripheral Device using this framework.
