Upgrade MacBook Pro Mid 2012 to Bluetooth 4.0?

I just bought a bluetooth midi controller device and now I find out it needs ‘bluetooth 4’ and won’t work with my MacBook as is..

Is it possible to swap out a card or something in the MacBook so I can have bluetooth 4?

And if so, what part number do I need to get?

Thanks muchly!

Unfortunately, the Wifi and Bluetooth card in the laptop uses a proprietary connector so there is no way to upgrade it internally. However, you could buy a USB Bluetooth 4.0 dongle and use that. The only drawback is it will take up one of your USB ports whenever you use it.

You know what’s weird?

When I look up the factory specs of this machine (, for instance on (but even here on ifixit: - I’m told it sports ‘Bluetooth 4.0’….

And yet, when I go to ‘System Report’ on my machine - it clearly reads: ‘LMP Version: 2.1 (0x4)’.

It’s a second-hand MacBook - is it possible someone previously downgraded it? Or is the information on these websites just wrong? - or indeed, is my mac's 'System Report' throwing an error?

Thanks for any thoughts…

EDIT: (just doing some extra research and it seems Bluetooth 2.1 came out in 2007 and was superseded by 3.0 in 2009 - I'd be very surprised if a top-range MacBook from 2012 came with 2.1!!

Have I been swindled? - I bought this MacBook from an eBay 'dealer' - they are known to swap out expensive RAM for cheap etc. can't say I'd see it being worth swapping out a WI-FI card.. but, maybe??)


Hi blue,

have you found out more? I have the same model Macbook Pro and my System Report also reads LMP Version: 2.1 (0x4). I also bought it second hand off eBay.
