Apple Silicon M1 Mac connecting 30" Apple Cinema Display
I purchased a new USB-C to Mini DisplayPort adapter.
This adapter works fine connected to an M1 Mac, Apple Mini DisplayPort to Dual-Link DVI Adapter, and 30&quot; Apple Cinema Display.

I was previously using the same type of connector, but a few years older and from a different brand:

But that adapter does not work on my M1 Mac. It does work with Intel USB-C Macs.
I would be interested to know why the original adapter does not work. Do M1 Macs require some additional spec?
