2012 iMac can't find Apple TV for mirroring
So I just received my new 2012 iMac and for some reason I just can't get the mirroring to work. When I go to displays it says "No Devices Detected" and I made sure to turn the Airplay on the Apple TV on as well.
Has anyone experienced this? I don't really know how I should go about troubleshooting in this situation, not sure if it's my computer or the Apple TV, or just a setting I missed. Any help would be appreciated, thanks!
