Apple today announced that it has released new 12-inch MacBook models with the latest sixth-generation Skylake dual-core Intel Core M processors up to 1.3 GHz, new Intel HD Graphics 515 that deliver up to 25% faster performance, faster PCIe-based flash storage, an additional hour of battery life, and faster 1866 MHz memory.



The ultra-thin notebook has the same all-metal unibody enclosure that remains 13.1 mm thick and weighs just 2 pounds, with a full-sized butterfly mechanism keyboard and Force Touch trackpad. Like the original model, the new 12-inch MacBook is also fanless and has no moving parts or vents.

The notebook continues to have a 12-inch display with a 2,304-by-1,440 resolution at 226 PPI, single USB 3.1 Type-C port, 256GB or 512GB flash storage, 802.11ac Wi-Fi, Bluetooth 4.0, a 480p FaceTime camera, stereo speakers, dual microphones, and a 3.5mm headphone jack.

The one-hour improvement to battery life, which is now up to 10 hours, was achieved not only by more efficient Skylake processors, but also due to a larger 41.4-watt-hour lithium-polymer battery. The original 12-inch MacBook has a slightly smaller 39.7-watt-hour battery that lasts up to 9 hours per charge.

The refreshed 12-inch MacBook models are available through Apple's online store starting today, and at Apple retail stores and select Apple Authorized Resellers starting tomorrow. The base 1.1GHz Core m3 model costs $1,299, while the faster 1.2GHz Core m5 model costs $1,599. The 1.3GHz Core m7 is a $250 upgrade.

In addition to Rose Gold, the 12-inch MacBook remains available in existing Gold, Silver, and Space Gray colors.

Apple has also made 8GB of memory standard across all 13-inch MacBook Air configurations.
