> Why does Apple need to make the drivers in a walled garden?

Isn't that the whole point of the walled garden, that they approve things? How could they aim and realize a walled garden without making things like that have to pass through them?

I think the OP is asking why Apple is enclosing macs in a walled garden when that concept is generally associated with iPhones, not general-purpose computers.

TFA is a little unclear, but I think it might be a (userspace) driver signing situation?
