If you’re concerned someone may have had physical access to your device and tampered with its built-in security, you can restore the device to its factory settings—even if you aren’t running the latest version of iOS, iPadOS, and macOS. A factory restore erases the information and settings on your device. This includes removing any apps that were installed without your knowledge and resetting your privacy settings so you aren’t sharing location with any people or apps. It also installs the latest version of the operating system.
This process, known as Erase All Content and Settings, requires internet access and can take some time; however, it helps ensure that your device can be accessed only by you.
Important: When you use Erase All Content and Settings, all your data is erased.
If you want to use Erase All Content and Settings on your Mac, you must be running macOS 12.0.1 or later. Alternatively, you can erase your Mac. See the Apple Support articles Use Disk Utility to erase a Mac with Apple silicon and Use Disk Utility to erase an Intel-based Mac.
