macOS version history

Mac OS X was launched more than two decades ago on March 24, 2001. There’s been a lot of change over those two decades: good and bad. From the problems with the first edition (it was slow and didn’t run important apps like Microsoft Word) Mac OS X has evolved through various iterations and various designs to what we know today. We’ve seen tight integration with iOS devices, the incorporation of the cloud, and the arrival of excellent and helpful features including integrated Time Machine backups, Quick Look – which lets you see a preview of a document without opening the application, and innovations like Expose and Spaces and Desktop Stacks to help you work more efficiently.

For an overview of the features of the various versions of the Mac operating system, showing how it has developed over time, take a look at our video above. If you want to know the names Apple assigned to Mac OS X over the years, and the codenames that were used internally, read on.

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 all named after big cats, from Cheetah to Panther to the final release, Mountain Lion.

But while the public-facing builds were named after big cats, internally, they were named after wines (aside from OS X 10.6 which had no codename).

Even after Apple switched public-facing code names to places in California back in 2013, it carried on naming them after wines internally until 2014. In 2015, Apple decided to change the theme of internal code names from wines to types of apples. Original.

In 2016, Apple took the plunge to unify the branding of its operating systems by rebranding Mac OS X to macOS, which sits nicely alongside iOS, tvOS, and watchOS and paved the way for macOS 11, the successor to Mac OS X, which arrived twenty years after the first beta of Mac OS X.

Which versions of macOS are still updated?

Apple still supplies regular features and security updates to the most recent version of macOS. Right now this is Sonoma, also known as macOS 14.

The previous two versions of macOS also receive security updates and bug fixes. If you are running macOS 13 Ventura and macOS 12 Monterey you will get regular security updates.

Since the arrival of Sonoma, Apple no longer supports macOS Big Sur, which arrived in 2020. Similarly, with the arrival of Ventura in October 2022 Apple ceased support for Catalina, which arrived in 2019. See: How long do Macs and MacBooks last?

Apple also issues updates to its Safari web browser. The latest version of Safari for Mac is Safari 17 (as of September 2023) and it requires Monterey, Ventura or Sonoma.

How to install the latest version of macOS

If you want to update your Mac to a newer version of macOS the method will be determined by the version of macOS you are running.

Very old versions of Mac OS X came on a disk and any security updates came via Software Update. Since the arrival of the Mac App Store in 2011 (as an update to Snow Leopard) versions of Mac OS X and macOS have been available to download via the Mac App Store.

However, that changed with Mojave, which arrived in 2018. Now operating system updates come in via Software Updates which is either located in System Settings> General> Software Update or in System Preferences> Software Update (pre-Ventura). One of the benefits of this is that your Mac can be set to automatically download the latest updates and install them, keeping your Mac up-to-date with minimum effort on your part. Incidentally, you can still find the macOS software on the Mac App Store.

Some Macs will be set to update macOS automatically. If you want your Mac to update automatically follow these steps:

In Ventura or later:

Open System Settings.
Click on General.
Click on Software Update.
Click on the i beside Automatic Updates and make sure that Check for updates, Download new updates when available, and Install macOS updates are selected. This way your Mac will automatically update to the latest version. If you would prefer not to have your Mac do this automatically you can deselect these options.

In Monterey, Big Sur, Mojave, or Catalina:

Open System Preferences.
Click on Software Update.
Check the box beside Automatically keep my Mac up to date (or Download new updates when available).
Now select the box Install macOS updates.

In High Sierra or earlier:

Open System Preferences.
Click on App Store.
Check the box beside Automatically check for updates – it should have a tick in it as should the four options below that…
Now deselect the box beside Download newly available updates in the background.
