Small update: I’ve had a response from the MFi team who have said to refer to the ‘Who does not need to join’ section on the MFi FAQ page. (See attached), which says this:
- Developers and manufacturers of non-electronic accessories, including non-MagSafe cases and Apple Watch bands. Get guidelines and resources for designing accessories that do not incorporate MFi licensed technologies.
I pressed them and they said the same thing. So I’ve written back again to say this isn’t helpful and that I need to know in no uncertain terms whether I can integrate the button without licensing from Apple. I’ll let you know what they come back with.
