Get High Sierra from the App Store
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 High Sierra, or go directly to the macOS High Sierra page.
- Click the Download button on the High Sierra page. A file named Install macOS High Sierra downloads to your Applications folder.
- After download is complete, the installer opens automatically. Click Continue and follow the onscreen instructions.
You may be asked to sign in with an administrator name and password to install a helper tool, then click Add Helper to continue.
Get High Sierra as an automatic download
If you're using OS X El Capitan v10.11.5 or later, High Sierra conveniently downloads in the background, making it even easier to upgrade your Mac. When the download has completed, you receive a notification indicating that High Sierra is ready to be installed. Click Install in the notification to get started.
If you want to install High Sierra later, just dismiss the notification. Install it at any time by opening the file named Install macOS High Sierra from your Applications folder, Launchpad, or Spotlight. Or delete the installer by dragging it to the Trash. You can always get it again from the App Store.
- 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 High Sierra requirements, you might be able to upgrade to El Capitan.
- If you previously downloaded El Capitan, Yosemite, Mavericks, or another earlier version of macOS, you can download it again from the Purchased tab of the App Store.
