How to download macOS Sierra

Apple recommends High Sierra, the latest version of macOS, to get the latest security and compatibility enhancements. But if you need the previous version, you can download Sierra here.

Can your Mac use Sierra?

macOS Sierra requires any of the following Mac models and versions of macOS. It also requires at least 2GB of memory and 8.8GB of storage space. To find your model, memory, storage, and macOS version, choose About This Mac from the Apple () menu.

  • OS X El Capitan
  • OS X Yosemite
  • OS X Mavericks
  • OS X Mountain Lion
  • OS X Lion

* The version of macOS that came with your Mac is the earliest version compatible with that Mac.

Get Sierra from the App Store

Now that High Sierra is available, you should upgrade to High Sierra instead of Sierra. For security and compatibility reasons, Apple always recommends using the latest version of macOS. 

If you still need Sierra, follow these steps:

  1. Use this link to open the macOS Sierra page on the App Store: Get macOS Sierra.
  2. Click the Download button on the Sierra page. If your Mac is compatible with Sierra, a file named Install macOS Sierra downloads to your Applications folder.
  3. After download is complete, the installer opens automatically. Click Continue and follow the onscreen instructions.

Don't have the Mac App Store?

If you're using Leopard, upgrade to Snow Leopard to get the App Store. Then check for software updates by choosing Software Update from the Apple menu. After installing all Snow Leopard updates, you should have the App Store app.

  • 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 you have hardware or software that doesn't meet the Sierra requirements, you might be able to upgrade to El Capitan, the previous version of macOS.
  • If you previously downloaded El Capitan, Yosemite, Mavericks, or another earlier version of macOS, and your Mac is compatible with that version, you can download it again from the Purchased tab of the App Store.
