Magic Trackpad 2 is rechargeable with a built-in battery and brings Force Touch to the desktop for the first time. Four force sensors underneath the trackpad surface allow you to click anywhere, and detect subtle differences in the amount of pressure you apply, bringing increased functionality to your fingertips and enabling a deeper connection to your content. Magic Trackpad 2 also features an edge-to-edge glass surface area that is nearly 30 percent larger than the previous trackpad along with a lower profile. This new design makes scrolling and swiping through your favorite content more productive and comfortable than ever. Magic Trackpad 2 pairs automatically with your Mac. The battery will power your Magic Trackpad 2 for about a month or more before needing a recharge. - Height: 0.190.43 inch (0.491.09 cm) - Width: 6.3 inch (16.0 cm) - Depth: 4.52 inches (11.49 cm) - Weight: 0.51 pound (0.231 kg)* - Force Touch - Multi-Touch Connections and Expansion: - Bluetooth - Lightning port - Wireless - System Requirements: Bluetooth 4.0-enabled Mac computer with OS X v10.11 or later Compatibility: - MacBook (Retina, 12-inch, Early 2015 - 2017) - MacBook Air (Retina, 13-inch, 2018 and later) - MacBook Air (13-inch, Early 2015 - 2017) - MacBook Air (11-inch, Early 2015) - MacBook Pro (13-inch, 2016 and later) - MacBook Pro (Retina, 13-inch, Late 2012 - 2015) - MacBook Pro (15-inch, 2016 and later) - MacBook Pro (Retina, 15-inch, Mid 2012 - 2015) - iMac (Retina 4K, 21.5-inch, 2019) - iMac (Retina 4K, 21.5-inch, 2017) - iMac (Retina 4K, 21.5-inch, Late 2015) - iMac (Retina 5K, 27-inch, 2019) - iMac (Retina 5K, 27-inch, 2017) - iMac (Retina 5K, 27-inch, Late 2014 - 2015) - iMac Pro (2017 and later) - Mac Pro (Late 2013) - Mac mini (2018) - Mac mini (Late 2014)
