The airplay code is displayed on the TV but not accepted on my computer [iMac]
I am running MacOS Sierra 10.12.6 on an 21" iMac [2015] and Apple TV 4th Generation. AirPlay is active on a 50" Panasonic flat screen. The WiFi network is FIOS Gigabit. All devices [AppleTV, iMam, MacBookPro and 2 Phones are all on the same network.
From the iMac, I clicked the TV icon, click on'Living Room', the location of the TV and I am presented with a dialog box requesting the 'AirPlay Device Password'. I enter the 4-digit password that appears on the TV screen and it is rejected., "This code is incorrect."
What am I missing?
