Check compatibility

macOS Big Sur supports most Mac models introduced in 2013 and later.

The OS X 10.11 El Capitan upgrade is available only at the Mac App Store, which means if you have versions Snow Leopard 10.6.7, Mavericks, Yosemite, Lion, and Mountain Lion, the Mac App Store already exists on your computer.
