It's simple and intuitive to use, and the macOS 12.3 Beta 2 update adds an icon that you'll see in the menu bar indicating that it's activated.
When headsets are connected to a Mac, maOS Monterey 12.3 adds support for updating AirPods firmware. In addition, it removed the kernel extensions used by Dropbox and Microsoft's OneDrive and removed Python 2, which Apple instructed developers to use alternative scripting languages such as Python 3.
