If you want to check compatibility before downloading the installer, find out more about the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan or Yosemite. You can also check compatible operating systems on the product ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini or Mac Pro.
