Mac OS X and macOS names
As you can see from the list above, with the exception of the first OS X beta, all versions of the Mac operating system from 2001 to 2012 were named after the big cats from Cheetah to Panther to Mountain Lion.
But when public-facing buildings were named after the big cats, internally, they were named after the wine (except for OS X 10.6 which had no codename).
Even after Apple changed public-facing code-names in places in California in 2013, it continued to name wines internally until 2014. Original.
In 2016, Apple rebranded Mac OS X to MacOS to integrate the branding of its operating systems, which sat well alongside iOS, tvOS and watchOS, and paved the way for MacOS X’s successor, MacOS 11, Mac OS. Twenty years after the first beta of X.

How to install the latest version of macOS
If you want to update your Mac to a newer version of macOS, the procedure will be determined by the version of macOS you run.
Older versions of Mac OS X came on a disk, and any security updates came with software updates. Mac OS X and macOS versions have been available for download through the Mac App Store since the arrival of the Mac App Store in 2011 (as an update to Snow Leopard).
However, this has changed slightly with Mojave, which came in 2018. Now operating system updates come through a new software update pane in System Preferences. You can still find the software in the Mac App Store, but you’ll also find it in System Preferences> Software Updates. One advantage of this is that your Mac can be set up to automatically download and install the latest updates, leaving your Mac up-to-date with minimal effort on your part.
You can get System Preferences from the Apple menu: Click the Apple logo at the top left and select System Preferences. If you do not click on the software update cog icon, you may be taken directly to the software update pane. Your Mac will search for an update and if there is one you can choose to update now
Some Macs will be set to automatically update macOS. If you want your Mac to update automatically, follow these steps:
In Monterey, Big Sur, Mozave or Catalina:
- Open system preferences.
- Click on Software Update.
- Check the box next to Download new updates if available.
- Now select the Install MacOS Update box.
Upper Sierra or earlier:
- Open system preferences.
- Click on App Store.
- Check the box next to Check for automatic updates – it should have a tick like the four options below …
- Now deselect the box next to the newly available update download in the background.
