You could hear a cheer from tech fans worldwide go up on Monday as Apple confirmed it was moving to USB-C Mac accessories alongside the launch of the iMac M4. But as wonderful as it is to see the Magic Keyboard, Magic Mouse and Magic Trackpad ditch the old Lightning port, Apple's added a wrinkle to this news that could make upgrading your Mac set-up slightly tricky.
Early adopters of the USB-C peripherals writing on the MacRumors Forums are reporting that unless your Mac's running the latest update of macOS — macOS Sequoia 15.1 — the accessories don't behave properly. Users on macOS Sonoma and macOS Ventura, the two previous macOS versions, claim that key features like scrolling on the mouse or the keyboard's Touch ID and function keys don't work. Users on the launch version of macOS Sequoia also faced this problem until they installed the 15.1 update.
