Get a bird's eye view with Mission ControlĪpple's Mission Control has been around in some capacity since Mac OS X Lion, and works a little like multitasking on your iOS device. Bottom line: if your hardware can support the new version of MacOS - here's a list of supported systems - it's totally worth the free upgrade.

It provides new ways to share across and synchronize Apple devices, and brings Apple Pay to the desktop. In addition to leveraging the TouchBar, the newest version of Sierra (release 12.10.1), for the first time integrates Apple's voice-enabled assistant, Siri, with the Mac operating system. Sliders, hot keys and function buttons emerge on the fly as needed. Exhibit A: the Touch Bar, a mini display that runs along the top of the keyboard that provides different icons and options for different apps. The common theme among the MacOS Sierra release and the new MacBook models is a greater emphasis on usability and productivity, rather than performance per se.

There's also a less expensive 13-inch model without the Touch Bar. Considerably slimmer, faster, and pricier than their predecessors, the new models feature some innovative flourishes - most notably, Apple's dynamic Touch Bar. In November 2016, the company refreshed its lineup of 13- and 15-inch MacBook Pros.
