Following the iPhone and iPad, Apple-based Macs and Intel Macs (2017-2020 models) equipped with the T2 Security Chip now offer an “Erase All Content and Settings” option in macOS Monterey and later. This article explains how to use it to erase and factory reset your Mac if you plan to give it away, sell it, or trade it in.

Traditionally, wiping a Mac and restoring it to factory settings required manually logging out of a series of services, erasing the Mac's internal drive, and then reinstalling macOS. These steps are complicated, especially when you consider how easy it is to wipe your iPhone or iPad. To do this simply select an option called "Delete all content and settings" in iOS (available in Settings - General - Transfer or Reset iPhone Find>).
Luckily, Apple is bringing the same option to newer Macs running macOS Monterey and later. Erase All Content and Settings in macOS provides a very simple and straightforward way to erase your Mac without reinstalling the operating system. Because of the way storage is encrypted on Macs with Apple chips or T2 chips, this option provides the ability to instantly and securely "erase" all user dates by destroying the encryption keys. Not only does this effectively erase all user data and user-installed apps from your Mac without reinstalling macOS, it also logs out of your Apple ID, removes your Touch ID fingerprint, Purchases and all Apple Wallet items, and turn off Finder and Activation Lock, making it easier to restore your Mac to new factory settings. The following steps demonstrate how to complete the operation. Whether you want to start using your Mac again or plan to sell or give it to someone else, after you erase your computer using this option, your Mac will display the Setup Assistant and be ready to set up like a new computer.The above is the detailed content of How to erase all content and settings on your Mac.
