What adapter can I use to connect an older Apple Cinema Display (mini displayport) to a 2017 iMac's thunderbolt 3 (USB-C) ports? Lots of confusion about all kinds of adapters that aren't working. Also lots of reports saying a standard mini displayport --> USB-C adapter will not work with 2017 Macboook Pro thunderbolt 3 (USB-C), so am wondering if the same is true with 2017 iMac. Anyone successfully running a mini displayport Apple Cinema Display on a 2017 Mac with thunderbolt 3 (USB-C) ports? What adapter works? If someone can point me to a specific adapter that is going to work, that would be great.
