Can not record iPhone screen from OSX Why am I not able to record screen of my iPhone. Others can do it. iPhone has iOS 8, Mac has Yosemite.

Here I can see Christoper's iPad on one of my computer, but not on my other Mac.
This is likely a bug in QuickTime Player. It recognizes both of my iDevices, but not a couple of family member's iDevices. All I could say is try updating the iPad to iOS 9, in the event that it's the iPad acting up.
