On September 20, 2016, Apple released its new operating system, macOS Sierra. We'd like to offer you a brief overview and answer any questions you may have at this time.
macOS Sierra is an operating system for desktop and laptop computers. It is version 10.12 of the OS X series of operating systems. In contrast to previous versions of OS X, Apple has dropped the "X" to make the branding more consistent with its other products, including iOS and watchOS.
Sierra is available now—it was released September 20, 2016.
Like OS X El Capitan, Sierra is a free upgrade.
Anyone with a newer Apple computer can upgrade to Sierra. However, some Macs from 2010 and earlier will not be able to upgrade, even if they met the requirements for El Capitan or Yosemite. The following models can upgrade to macOS Sierra:

Although the overall interface is similar to previous versions of OS X, there are some significant changes:

Almost all apps installed on your computer should work correctly in macOS Sierra. However, as with any new operating system, some software may not be totally compatible. A simple Google search will often be enough to tell if an app will be compatible with Sierra.
