Cannot watch MLS games on Apple TV App on Mac Studio

Hello Jonathan Myers,

Welcome to Apple Support Communities. 

We understand that you’re unable to watch MLS games from the Apple TV app on your Mac Studio. We are happy to help.

We’d like to have you try some isolating troubleshooting steps—safe mode and test in a new user account.

Here’s how to use safe mode:How to use safe mode on your Mac - Apple Support

Here’s how to add a new user account to test: Change Users & Groups settings on Mac - Apple Support

"Create a new user or group.

Click the New Account pop-up menu (you may be asked to enter your password), then choose a type of account.

• Administrator: An administrator can add and manage other users, install apps, and change settings. The new user you create when you first set up your Mac is an administrator. Your Mac can have multiple administrators. You can create new ones, and convert standard users to administrators. Don’t set up automatic login for an administrator. If you do, someone could simply restart your Mac and gain access with administrator privileges. To keep your Mac secure, don’t share administrator names and passwords.
• Standard: Standard users are set up by an administrator. Standard users can install apps and change their own settings, but can’t add other users or change other users’ settings.
• Sharing Only: Sharing-only users can access shared files remotely, but can’t log in to the computer or change settings. To give the user permission to access your shared files or screen, you may need to change options in File Sharing, Screen Sharing, or Remote Management settings. See Set up file sharing and Share the screen of another Mac.
• Group: Groups allow multiple users to have the same access privileges. You control a group’s access to your shared folders by setting access permissions in the File Sharing options in Sharing settings.

See Add a user or group."

Take care.
