From 2001 to 2012, OS X was code-named internally (for development purposes) after big cats. Becuase Apple marketing was also using those code-names to promote OS X publicly, however, the company's development crew switched their internal naming structure to wines beginning with OS X 10.3 — publicly known as Panther, privately as 'Pinot.' (Apple did make one exception for OS X 10.6, which never had a code-name beyond Snow Leopard.)

Though Apple's external code-names for OS X switched to California places in 2013, the internal code-names remained wine-based until 2014. In 2015, the development team switched to types of apples, with OS X 10.11 El Capitan (AKA 'Gala').

In 2016, OS X officially became macOS, though Apple continued using California places as the external code names, and apple types as the internal code names. So far, this has remained the internal code name across the board.

Apple's code names

Main

Is your Mac up to date with the latest version of the Mac operating system (macOS or OS X)? Is it using the version required by some product or feature? Which versions are earlier (older) or later (newer, more recent) than the version currently installed? To find out, learn which version is installed now.

If your macOS isn't up to date, you may be able to update to a later version.

Which macOS version is installed?

Mac Os Versions For Download

From the Apple menu  in the corner of your screen, choose About This Mac. You'll see the macOS name, such as macOS Mojave, followed by its version number. If some product or feature requires you to know the build number as well, click the version number to see it.

Which macOS version is the latest?

These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Mojave. And as updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.

Mac Os Versions And Names
