I have MacBook Pro 15inch mid 2014, https://support.apple.com/kb/sp704 It works still fine after all these years. Only problem now is that I use my AirPods Pro with it. It works fine for music of video's. With with calling or zoom meetings the quality is very bad. This is a problem with the Bluetooth chip, its 4.0. Is it a possibility to use a Bluetooth 4.2 or 5.0 dongle and disable the internal one? And can somebody recommend a dongle?
