Which releases of macOS are supported with security updates?



Apple has no written policy guaranteeing how long it will support each release of macOS with security updates. But you can quickly check which versions of macOS Apple is still updating, and they usually support the most recent three versions.

Apple has no official written policy

Apple makes no written statement guaranteeing how long it will support each release of macOS with security updates. Apple doesn̵

7;t even publicly say when an operating system is “end of life” and will no longer receive updates. They just stop releasing updates to old versions of macOS without notice, and you’re on your own.

This is very unusual if you are used to working with Microsoft Windows. Microsoft publishes their Windows Support Lifecycle, which describes (and guarantees) exactly how long each product will receive different types of updates. For example, you can see on that page that for Windows 7 Service Pack 1, regular support (new feature releases and minor updates) ended in 2015, but extended support (security updates) runs until 2020.

However, Apple still has a plan, even if they don’t describe it publicly. Apple has consistently updated the last three versions of macOS, in other words, the current release of macOS and the last two releases, with security updates for a number of years. So, assuming Apple releases a new version of macOS every year, every release of macOS is supported with security updates for about three years. But Apple makes no guarantees, and that’s just an educated guess.

How to see what is currently supported

The Apple Security Updates page is the only page on Apple’s website that gives you this information. It contains a list of security updates that Apple has recently released for all of its devices, including Macs running macOS. Look for the most recent macOS update and check which versions of macOS it was released for. If a version of macOS does not receive new updates, it is no longer supported.

For example, in May 2018, the latest version of macOS was macOS 10.13 High Sierra. This release is supported with security updates, and the previous releases, macOS 10.12 Sierra and OS X 10.11 El Capitan, were also supported. When Apple releases macOS 10.14, OS X 10.11 El Capitan will most likely no longer be supported. At least that’s what we can assume based on Apple’s past actions.

How to check which version of macOS you are using

To see which version of macOS you’re using, click the Apple icon in the menu bar at the top of your screen, then click the “About This Mac” command. You will see the name of the release you are using and the version number below it.

If you have an older minor release, for example if you have macOS 10.13.3 and you see that only macOS 10.13.4 is supported with updates, all you need to do is open the Mac App Store and install any updates to get the latest minor releases. version.

Upgrading to a supported release

You can always upgrade to a new release of macOS for free, assuming Apple still supports your hardware. Launch the App Store app on your Mac and you should see the new version of macOS as a free download. It’s a good idea to back up your Mac before proceeding.

You can also click the “Software Update” button in the About This Mac window to open the app.
