Mac OS X and macOS names
From the given list, it is evident that, except for the initial OS X beta, all Mac operating system versions released between 2001 and 2012 were named after large feline species, ranging from Cheetah to Panther to the last one, Mountain Lion.
However, the publicly released versions were named after large felines, while their internal names were based on types of wine (except for OS X 10.6, which did not have a codename).
Although Apple changed its public code names to locations in California in 2013, it continued to use wine names internally until 2014. However, in 2015, Apple made the decision to switch from using wine names to using types of apples for internal code names. Original.
In 2016, Apple made the decision to consolidate its operating systems under one brand by changing Mac OS X to macOS. This name now aligns with other operating systems such as iOS, tvOS, and watchOS. This paved the way for macOS 11, the next version after Mac OS X, which was released twenty years after the initial beta of Mac OS X.

The steps to install the most recent version of macOS.
To upgrade your Mac to a more recent macOS version, the approach will depend on the current macOS version installed on your device.
Earlier editions of Mac OS X were distributed on a physical disk, and any necessary security updates were obtained through Software Update. However, since the launch of the Mac App Store in 2011 (as an upgrade to Snow Leopard), users have been able to download versions of Mac OS X and macOS directly from the Mac App Store.
In 2018, the arrival of Mojave brought about a change. Instead of obtaining operating system updates through the Mac App Store, they now come through Software Updates, accessible in either System Settings or System Preferences. This feature allows for automatic downloading and installation of updates, making it easier to keep your Mac current. However, the macOS software can still be found on the Mac App Store.

In the future, specifically in Ventura:
- Open System Settings.
- Click on General.
-
Select the option for Software Update.
-
To enable automatic updates on your Mac, select the “i” next to Automatic Updates and ensure that Check for updates, Download new updates when available, and Install macOS updates are checked. This will ensure that your Mac is always running the latest version. If you do not want your Mac to update automatically, simply uncheck these options.
In the areas of Monterey, Big Sur, Mojave, or Catalina:
- Open System Preferences.
-
Select the option for Software Update.
- Check the box beside Automatically keep my Mac up to date (or Download new updates when available).
-
Please choose the option to install macOS updates.
