List of all macOS versions – including the latest macOS

Wondering what the name of the latest macOS version is? Curious about the versions of Mac OS X that came before? Here we’ll fill you in on the names of the different versions of the Mac operating system in order: from the newest macOS to the first version of Mac OS X and the codenames that Apple used for them. We’ll also show you how you can check which version of macOS you are running and find out what the latest version of macOS is.

If you are wondering what the latest version of macOS is it’s Monterey! Also known as macOS 12. Monterey arrived on Monday 25 October 2021. For more information read: Everything you need to know about macOS Monterey.

However, Monterey won’t be the newest version of macOS for long. Apple will be unveiling its plans for the next version of macOS at its Worldwide Developers Conference (WWDC) in June 2022. At the keynote that kicks off the WWDC conference Apple will reveal details of macOS 13 – including its name. The final version will then be available to download in the fall (usually in the September or October time frame).

Mac OS X first launched more than 20 years ago on 24 March 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 back ups, 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 efficiently.

In this article we will run though the long history of Mac OS X, or macOS as it is now known. 

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 & 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 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 apple. 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.

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 slightly with Mojave, which arrived in 2018. Now operating system updates come in via a new Software Updates pane in System Preferences. You can still find the software in the Mac App Store, but you will also see it in System Preferences > Software Update. 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.

You can get to System Preferences from the Apple menu: Click on the Apple logo in the top left and choose System Preferences. You may be taken straight to the Software Update pane, if not click on the Software Update cog icon. Your Mac will search for an update and if there is one you can choose Update Now.

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

In Monterey, Big Sur, Mojave or Catalina:

1. Open System Preferences.
2. Click on Software Update.
3. Check the box beside Download new updates when available.
4. Now select the box Install macOS updates.

In High Sierra or earlier:

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