Apple launched the macOS Sierra 10.12.2 update to the public last week, the second major update since Sierra?s September launch. The 10.12.2 update focuses entirely on a wide variety of fixes and under-the-hood improvements, but also a couple of new features. The rollout specifically addresses several issues with the 2016 MacBook Pro models, including the graphics and battery life problems.

Battery Issue

The most visible feature change is the removal of the battery?s ?time remaining? display. Before Apple?s MacOS 10.12.2 update, 2016 MacBook Pro users complained of shorter than expected battery life. The users took to Apple?s support communities and internet forums and broader consensus was forming that new laptops could achieve only 3 to 6 hours of battery life.

Apple?s solution to the problem is to stop reporting estimated remaining time. The macOS 10.12.2 update removes the indicator showing the hours and minutes left before your battery dies. Besides the removal of time indicator, Apple has introduced some surgical software changes that has lead to greater battery endurance, reports Forbes. Reports indicate longer life on the 2016 Macbook Pro after the installation of battery life.

Another significant fix in the new update addresses the graphics issues on the 2016 MacBook Pro models. Some users were affected by ?flickering, full-screen checkerboard patterns, screen tearing, and other visual artifacts,? in the words of MacRumors. The MacOS 10.12.2 update will fix these graphics issues.

Fixes Security Flaw

In addition, the latest version of Apple?s computer operating system protects your Mac password. A Swedish hacker, Ulf Frisk, shared details of a vulnerability in macOS 10.12.1 and lower, that allows anyone with physical access to a locked Mac to easily obtain the password with a $300 Thunderbolt device.

Frisk notified back in August, and Apple confirmed the issue and asked him to withhold details pending a fix. He reports that the vulnerability is no longer present in macOS 10.12.2.
