How to download macOS

Download and install current or previous versions of the Mac operating system.

Apple recommends using the latest (newest) macOS that is compatible with your Mac. macOS updates and upgrades help to maintain your computer's security, stability and compatibility, and they include the latest features and built-in apps.

Before installing, it's a good idea to back up your Mac. While installing, avoid putting your Mac to sleep or closing its lid. Your Mac will restart, and it may display a progress bar or blank screen several times. 

 


Use Software Update

Using Software Update is faster and easier than upgrading by other methods, and it might require less storage space to download and install the upgrade. Software Update will only display upgrades that are compatible with your Mac.

Update macOS on your Mac

 


Or use the App Store or your browser

When you use these methods instead of Software Update, your Mac might need more storage space to download macOS and complete the installation.
  

  1. Click the link to open the App Store page for that macOS. 
  2. In the App Store, click the Get button to start downloading the macOS installer.
  3. After downloading to your Applications folder, the installer will open automatically. Follow the onscreen instructions to install macOS.

 

  1. Click the link to download a disk image (.dmg) file for that macOS.
  2. Double-click the .dmg file to open it and see the .pkg file within.
  3. Double-click the .pkg file, then follow the onscreen instructions. This will install the macOS installer into your Applications folder.
  4. Open your Applications folder and double-click the macOS installer, named Install [Version Name]. Follow the onscreen instructions to install macOS.

 

If you need help

If you're having difficulty getting the links to work, try again using Safari. It's in your Applications folder.

If you need more storage space to download or install, find out how to free up storage space.

If the macOS that you want isn't compatible with your Mac or the currently installed macOS, the installer will let you know and the App Store may prevent you from downloading it. For example, it may dim the Get button, say that the macOS is not compatible with this device or say that the requested version of macOS is not available.

Find out what to do if you receive an error message saying that an error occurred while downloading, preparing or installing, or that the installer is damaged or could not be verified.

Other ways to update or upgrade macOS include using macOS Recovery or using a bootable installer.
