Apple's new iMac lineup features some of its most powerful processors—and its oldest peripheral design. Its fetish for the Lightning connector persists in a passel of peripherals.

Instead users have to attach a Lightning to dock connector adapter, which contains (among other chips) a DAC to take the digital Lightning input and outputs an analog line out signal over the dock ...

And connecting non-Lightning gear through a digital input would likely require another shopping spree for one of those $30 adapters Apple is so happy to supply.

I've seen plenty of people who decided to stick with their USB-A to Lightning cables and get an adapter that converts the Lightning input into USB-C.

They’re one of the few remaining devices that haven’t switched to USB-C and the ones that make the least sense. Quite frankly, Apple’s Mac accessories should have never had a Lightning port.
