Get connected

Catalina Installer Apple

It takes time to download and install macOS, so make sure you have a reliable internet connection. If you’re using a Mac notebook computer, plug it into an AC power source.

Download macOS Big Sur

If you're using macOS Mojave or later, get macOS Big Sur via Software Update: choose Apple menu  > System Preferences, then click Software Update.

Or use this link to open the macOS Big Sur page on the App Store: get macOS Big Sur. Then click the Get button or iCloud download icon.

Begin installation

After downloading, the installer will open automatically.

Click Continue and follow the on-screen instructions. You may find it easiest to start installation in the evening so that it can be completed overnight, if needed.

If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.

Allow the installation to be completed

Please allow the installation to be completed without putting your Mac to sleep or closing its lid. Your Mac may restart, display a progress bar or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.

Stay up to date

After installing macOS Big Sur, you will be notified when updates to macOS Big Sur are available. You can also use Software Update to check for updates: Choose Apple menu  > System Preferences, then click Software Update.

Or get macOS Big Sur automatically

If you're using OS X El Capitan v10.11.5 or later and your App Store preferences or Software Update preferences are set to download new updates when available, macOS Big Sur will download conveniently in the background, making it even easier to upgrade. A notification will inform you when macOS Big Sur is ready to be installed. Click Install to get started, or dismiss the notification to install later. When you're ready to install, just open the file named Install macOS Big Sur from your Applications folder.
