If something doesn't quite work right after you've installed macOS Catalina, you can reinstall the operating system so it is a fresh copy. Reinstalling a fresh copy of macOS Catalina will not affect your current settings. Applications and settings will remain the same. Completing this process replaces the core files of macOS Catalina in case something wasn't working right before.

Before you start: Back up your data

  • It is a good idea to perform one full backup before starting with a clean copy of macOS Catalina. You can also back up files and documents using a cloud-based storage system like Dropbox, OneDrive, or the easiest: iCloud.

  • Make sure the computer on which you're installing a fresh copy of macOS Catalina can be connected to the internet, either via Wi-Fi or Ethernet. This step is important. An Internet connection is needed in order to reinstall the macOS operating system.

  • If you are using a laptop, make sure it is connected to a power source.

How to install a new copy of macOS Catalina in Recovery Mode
