I recently got our old Xbox one up and running again, and my wife wants to play GTA V together. We don’t have 2 TVs but we do have a TV and an iMac. I ordered an adapter but it turns out it was the wrong direction. I have been searching for a while and I cannot find a cable/ adapter that will convert the HDMI signal to mini display for my 2009 iMac. Does anyone on here know of a cable that would do the trick?
