While macOS Ventura 13 is now available, there are still many Mac users who are using older versions of macOS, either because they can’t update to the new version or just don’t want to. Apple hasn’t forgotten these users–in fact, on Monday Apple released macOS Big Sur 11.7.1 and macOS Monterey 12.6.1, which include major security updates.
To install the updates, open System Preferences and click on Software Update. You may see an Upgrade Now section telling you to upgrade to macOS Ventura. If you do, click on the “More info” link under the sentence that reads, “Other updates are available.” A new window will appear, listing the update, and you can click Install Now to perform the installation. It will take several minutes and your Mac will need to restart.
