“macOS Sierra is Apple’s latest desktop operating system, which succeeds OS X El Capitan and adopts a new name to bring it in line with iOS, watchOS, and tvOS,” Tim Hardwick writes for MacRumors. “The OS will come pre-installed on all new Macs once current stock is depleted and is a free download for existing Mac owners. ”

“The main new feature in macOS Sierra is deep Siri integration, bringing Apple’s personal assistant to the Mac for the first time,” Hardwick writes. “It also adds new features to Photos and Messages, and includes Continuity smarts like Universal Clipboard and an Auto Unlock option for Apple Watch owners.”

“A clean install can remove annoying quirks and strange behaviors that your Mac may have inherited over time due to driver upgrades, wonky apps, and messy installation procedures,” Hardwick writes. “Performing a fresh install can also reclaim lost disk space caused by junk files left by third-party apps, and can generally make your Mac feel a lot snappier, enabling you to relive that feeling of booting it up for the first time. ”
