Mac users can also choose to download the update as a package directly from Apple, or to install the MacOS 10.12.2 Combo Update package if desired. The Mac will install the update and reboot automatically.
The time remaining battery estimator has been part of Mac OS X for over 15 years, but now Mac laptop users will have no automatic battery life estimate offered by the system software after installing Mac OS 10.12.2. MacOS Sierra 10.12.2 also removes the “battery time remaining” indicator from Mac laptops, apparently in response to some complaints about unsatisfactory battery life on 2016 model year MacBook Pro with Touch Bar. Additionally, MacOS Sierra 10.12.2 offers a few new desktop wallpapers, as well as many new Emoji icons, including a clown, bacon, a gorilla, cucumber, avocado, and a cowboy. MacOS Sierra 10.12.2 includes various bug fixes and improvements aimed to address some of the ongoing issues with Sierra experienced by some Mac users.
