macOS Sierra, the next-generation Mac operating system, was unveiled at the Worldwide Developers Conference on June 13, 2016 and launched to the public on September 20, 2016. Apple chose to do away with the OS X name in favor of the new “macOS” name to bring the Mac operating system in line with iOS, watchOS, and tvOS. The main new feature in macOS Sierra is Siri integration, bringing Apple’s personal assistant to the Mac for the first time. Siri offers many of the same capabilities available on iOS, along with Mac-specific functionality like the ability to search through documents to quickly find files.

ISO image refers to a CD, DVD or Blu-ray image file with an extension of “.iso”, which is composed of the data contents of every written sector of an optical disc, including the optical disc file system.
