The third beta of OS X 10.11.1 El Capitan seeded to developers on Wednesday contains references to a Magic Keyboard, Magic Mouse 2 and Magic Trackpad 2. The references were spotted by French website Consomac.
It is possible that Apple may be planning to ship the next-generation keyboard, mouse, and trackpad alongside the new 4K 2.15-inch Retina iMacs that are expected to ship next week.
Mentions of a new Apple Wireless Keyboard and Magic Mouse 3 first appeared in FCC filings back in August. Each boasts Bluetooth 4.2 and lithium-ion batteries. MacRumors notes that Apple has also registered a number of domains related to such products, including: applemagickeyboard.com, applemagickeyboard.net, and applemagickeyboards.com.
