Apple's new USB-C accessories, including Magic Mouse, Magic Trackpad, and Magic Keyboard, require macOS Sequoia to work properly.
Earlier versions of macOS, such as Sonoma and Ventura, do not fully support the new accessories, with issues ranging from non-functioning Touch ID and function keys to scrolling problems.
Even the first macOS Sequoia 15.2 beta lacks support for the new accessories, causing limited functionality.
Updating to macOS Sequoia 15 or 15.1 is currently recommended for proper use of the USB-C accessories.
