Check compatibility
OS X Mountain Lion is available now as a download from the Mac App Store. Just click the Mac App Store icon in your dock, purchase Mountain Lion, and follow the onscreen instructions to install it. Mountain Lion will not only make your Mac work better, it also makes your Mac work even better with your iPhone, iPad, and iPod touch. Because it comes with iCloud, your mail, calendars, contacts. Click the Install button. A sheet asks for your Apple ID and password. Type them in the appropriate fields; click Sign In, and your Mountain Lion installation (or reinstallation) begins. The operating system takes 30 to 60 minutes to install, so now might be a good time to take a coffee break. When the install is finished, your Mac restarts itself. Mountain Lion will download and the installer will automatically launch when the download is done. The installer will be deleted after it completes the install so if you want to save a copy quit the installer and copy the Install OS X Mountain Lion.app inside your applications folder somewhere else such as your Documents folder.
If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that your Mac doesn't have enough free storage space for the installation, or that the installer is too old to be opened on this version of macOS.
