• A backup of your important files: Make sure you have backed up all your important files and data to an external hard drive or cloud storage service.
• A USB recovery key or Internet recovery: You will need a USB recovery key or access to the Internet to download the necessary files.
• A compatible version of Mac OS: Make sure you have a compatible version of Mac OS for your Mac model.
