Learn how to upgrade to macOS Big Sur, the latest version of macOS.
Check compatibility
The version of macOS that came with your Mac is the earliest version it can use. For example, if your Mac came with macOS Big Sur, it will not accept installation of macOS Catalina or earlier.
If a macOS can't be used on your Mac, the App Store or installer will let you know. For example, it might say that it's not compatible with this device or is too old to be opened on this version of macOS. To confirm compatibility before downloading, check the minimum hardware requirements:
- macOS Catalina 10.15 hardware requirements
- macOS Mojave 10.14 hardware requirements
- macOS High Sierra 10.13 hardware requirements
- macOS Sierra 10.12 hardware requirements
- OS X El Capitan 10.11 hardware requirements
- OS X Yosemite 10.10 hardware requirements
Download macOS using Safari on your Mac
Safari uses these links to find the old installers in the App Store. After downloading from the App Store, the installer opens automatically.

- macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
