Apple’s new USB-C Magic Keyboard, Mouse, and Trackpad require macOS Sequoia 15.1 to work properly.
Older Macs running software like macOS Sonoma and macOS Ventura might have issues with the new accessories.
Some users have reported that pairing with older Macs is possible, but the keyboard, Touch ID, function keys, and Magic Mouse scrolling don't work properly.
Only specific Mac models support macOS Sequoia, and Apple may add more to the compatibility list in the future.
