airplay incorrect code

Hello melperez,

Just to confirm, are you being asked to enter an AirPlay password on Apple TV when trying to stream audio and video from your Mac with AirPlay? That information will help us determine how to proceed.

If you're being asked to enter an AirPlay password on Apple TV, the link you came from outlines what to do, and may help: If you're asked to enter an AirPlay password on Apple TV

The first time you use AirPlay with your Apple TV, you'll see an onscreen password. Enter the password into your device to stream content to Apple TV. Or if you're using Conference Room Display, a message will always appear on the display with AirPlay connection instructions and wireless network details.

If you're getting a password notification on your Apple TV, but aren't trying to use AirPlay, please be sure to check out the "If you see a password and aren't using AirPlay" part of the above link, as it outlines how to proceed:

If you see a password and aren't using AirPlay

If you see a password notification on your Apple TV and you aren't trying to use AirPlay, you might need to adjust your AirPlay settings. 

On your Apple TV, go to Settings > AirPlay and HomeKit.

From here, you can give your Apple TV a unique name and assign it to a room so you can easily identify it when you use AirPlay. You can also choose who can stream content using AirPlay to your Apple TV:

• Everyone: Anyone can see and stream content to your Apple TV.

• Anyone on the Same Network: Anyone connected to your home Wi-Fi network can stream content to your Apple TV.

• Only People Sharing This Home: People that you invite to control your home in the Home app can stream content to your Apple TV.

• Require Password: A password will be required before anyone can stream content to your Apple TV.

Thanks!
