Mac will suddenly not sync to appleTv
We have latest AppleTv. All has been working fine for 2 months. Suddenly today, our Mac will no longer sync to appletv. It was working fine just 2 hours ago. Homesharing is on, both on appletv and Mac. However, Mac will not recognized appleTv and appleTv icon has suddenly disapeared. We rebooted everything & still not working. I've read a few discussion boards and have yet to find a solution. Can anyone please help out?
Thank you.
