Earlier quoted context omitted.
> So if you sell a bluetooth device, it is legally required to work properly with every other bluetooth device on earth? It actually is. If you use either the Bluetooth patents or trademarks (e.g. logos and names), not only you must pass a certification that ensures this, you must also "maintain a level of quality that meets or exceeds industry standards", and this evidently doesn't.
Well, I've never got any non-Apple phones/computers to work with Apple phones/computers using Bluetooth.
I definitely use my macbook with non-apple hardware. From headphones to laptops to android phones.
My first Macbook used to pair with a Nokia E72 to get internet via the GSM modem, I used it every day on the train.
Two weeks ago I connected an old Oneplus One via bluetooth to my macbook (2020 mbp) to get some old photos from its internal memory.
What doesn't work?
EDIT: actually, I'm not sure I ever connected a laptop to a macbook, but I have a linux laptop so I can try it if you want.
