macOS Catalina Reviews

macOS Catalina Description

You can install macOS Catalina on these computers if you have OS X Mavericks 4.0 or higher. You also need at least 4GB memory and 12.5GB available storage space. If you are upgrading from OS X Yosemite, you can have up to 18.5GB storage space. It's essential to keep your software current to get the latest features, maintain stability, compatibility, performance, and security of your Mac. Apple recommends that you use the most compatible macOS version for your Mac. The macOS version that came with your Mac is what it can use. If your Mac came with macOS Big Sur it will not allow you to install macOS Catalina. The App Store or installer will inform you if a macOS cannot be installed on your Mac. It might state that the macOS is not compatible with your device or that it cannot be used on this macOS version.
