Hello CJMirch,
Thanks for reaching out to Apple Support Communities. We see you have some questions about watching Apple TV on your Mac, and we'd like to help. We see your Mac is using macOS 13.2. From here, let's try updating to see if that happens: Update macOS on Mac - Apple Support
Use Software Update
Before following these steps, it's a good idea to back up your Mac.
1. From the Apple menu in the corner of your screen, choose System Settings or System Preferences.
* If you chose System Settings, click General on the left side of the window. Then click Software Update on the right.
* If you chose System Preferences, click Software Update in the window.
2. Software Update then checks for new software.
* If Software Update finds new software, click the button to install it. The button might be named Update Now, Upgrade Now, Install Now, or Restart Now, for example. You might then be asked to enter your administrator password.
* If Software Update says that your Mac is up to date, then no new software is currently available for your Mac model. Software Update shows only software that is compatible with your Mac.
