What part would I need to buy to have bluetooth 4.0?
I have the 21.5 2011 iMac and although my bluetooth is working, I cannot use the new features of Yosemite because it's not bluetooth 4.0... it's 2.1. Based on this guide, I can indeed replace the bluetooth board, but is there a compatible bluetooth 4.0 board out there? I have scoured the internet and cant seem to find anything.
Is dit een goede vraag?
