Click the “Download” or “Get” button on the macOS Monterey page to download Monterey and install it on your Mac. The operating system is 12.1GB in size so it may take a while. The installer will automatically open after the download is finished. Click through it to install Monterey on your Mac.

Note: We highly recommend backing up your Mac with Time Machine (or however you back up) before upgrading your operating system. The upgrade should leave everything in place, but it’s always better to play it safe just in case.

Apple only supports the most recent three versions of macOS with security updates, so you have to upgrade regularly to ensure you have the latest security patches.
