How to get macOS Sierra
Before upgrading, it's a good idea to back up your Mac. Then follow these steps:
- Open the App Store app on your Mac.
- Search the App Store for macOS Sierra, or go directly to the macOS Sierra page.
- Click the Download or Install button on the macOS Sierra page.
- When the installer opens, click Continue and follow the onscreen instructions.
If you quit the installer instead of clicking Continue, you can open it later from your Applications folder, Launchpad, or Spotlight. Look for a file named Install macOS Sierra. During installation, your Mac might restart several times. It then performs some initial setup tasks in the background. While those tasks are underway, activities such as using Spotlight or Mail might not seem as fast as they were before.
- If your Mac doesn't meet the Sierra requirements, you might be able to upgrade to El Capitan, the previous version of the Mac operating system.
- If you previously downloaded El Capitan, Yosemite, Mavericks, or another earlier version of OS X, you can download it again from the Purchased tab of the App Store.
