Connectivity includes four USB 2.0 ports, a Firewire "800" port, built-in 802.11a/b/g/n Wi-Fi, Gigabit Ethernet, and an SDXC card slot as well as a single Mini DisplayPort. It does not support internal Bluetooth.

@mayer - I think you can add it with the missing parts.

I’m not sure if the antenna or data cable are even present in your system. For reference here’s the guide for the standard model iMac Intel 21.5" EMC 2428 Bluetooth Board Replacement and here’s the needed parts:

  • Bluetooth Board - 922-9902
  • Bluetooth Antenna - 922-9904
  • Bluetooth/Camera/Sensor Cable - 922-9802

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

Update (06/16/2020)

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

Others have done it so either you've got a bad part of you have a connection issue within the cabling to the logic board.

Not sure I understand why you tried going with the combo board as the Airport socket doesn't offer the needed USB connection for the Bluetooth services (both power and data).

Time to pull out the DVM and schematics & board views to trace things out.

Show me one person who has accomplished it Dan???

I have looked all over the Internet and have not found ONE person that can show it done. I have found many that tried, and all failed.

Can anyone recommend a usb - Bluetooth adapter that will work with OSX High Sierra?

I just want to use my Apple keyboard and Magic Mouse with this iMac.

Thanks.

@bigal666 - The original OP did it! Its been awhile I also know of someone else here that did it. There is no difference in the logic boards between the standard and EDU models. Apple only failed to install the needed parts.

I had the same problem and I was able to solve it with a Baseus USB Bluetooth Adapter. Not as elegant as the internal card, but works just fine.
