I have a 2011 iMac that I continue to use because it is still a champ. I also have a 15-inch MacBook Pro with TouchBar. As such, I have an assortment of both standard and USB C type cables I want to use with my desktop iMac. So my question is: Is anyone aware of a USB hub that connects via USB A, but features both USB A and at least one USB C port? Having a devil of a time finding one. Any recommendations?
