I use a third party thunderbolt dock, third party storage, third party keyboard adapter for a vintage Apple keyboard, third party monitor, speakers, camera, NAS, chargers.
What subtle, proprietary changes does Apple make to standardized connections that require Apple branded devices?
i'm talking about two things specifically: MFi, whatever they did to deviate from BLE for airpods advanced modes.
There was also something specific for Apps to make them behave as you want with accessories, you had to go through something simillar to MFi or work around with hacks.. but i really don't remember what that was called. we made do with workarounds years ago and never thought about it anymore
