I have a late 2011 iMac EDU model without bluetooth and I tried every possible solution including replacing AirPort Card with an Airport/bluetooth combo card, didn’t work, I added a full Bluetooth, iSight, Bluetooth antenna kit from Powerbook Medic with everything properly grounded, Bluetooth card installed on the top left above the lcd power board and connected to iSight and plugged in the middle if the logic-board, all went absolutely smoothly and still does not work so I don’t know what Apple did to this model but I does not support internal Bluetooth unless someone can tell me different? I even checked the hardware profile using terminal and installed working kexts and a known good profile pane and it’s just not there, seems to me it’s some kind of Bluetooth power issue and you somehow need a separate power source to activate the Bluetooth Adapter, if anyone has had success please advise

there is a board adapter you can buy on Aliexpress that has the 2012 and up iMac AirPort card that includes Bluetooth which includes the adapter but it doesn't work.. also I installed a complete kit including Bluetooth Card, Bluetooth/iSight USB cable and Bluetooth antenna into this imac and still no Bluetooth so apple didn't include either programming in the firmware to detect the Bluetooth or power to the Bluetooth because I have been repairing all Macintosh computers since the first PowerBook and I can't make it work and I did everything including forcing kext files for the hardware, resetting SMC, PRAM and force checking the devices in terminal, it can't be done period, save your time and money and buy a Mac comparable USB Bluetooth dongle
