Use AppleTV to connect to your Mac

• Start the 'System Preferences' App.
• Select 'Sharing'.
• From the 'Service' list on the left, ensure that 'File Sharing' is ticked (see 1 on screenshot).
• Under the 'Shared Folders' list, click +
• Choose a folder to share and click 'Add'.
• Click the "Options" button (see 2 on screenshot).

Log in and connect

Ensure that "Share files and folders using SMB" is enabled, because FileBrowser TV only uses SMB.

Make sure your account name is ticked - labelled C in the screenshot.

When FileBrowser TV asks for a login, this is the one to use.
