This guide covers two main topics: completely erasing your Mac to prepare it for sale, transfer, or a fresh start, and how to speed through the initial setup process on a new or erased Mac. ✨

If your computer is a Mac with Apple silicon, or an Intel-based Mac with the Apple T2 Security Chip that’s using macOS Monterey 12 or later, you can use Erase Assistant to reset your Mac to factory settings before you trade it in, sell it, or give it away.
If you have a different type of Mac, see Erase and reinstall macOS.

Erase Assistant does the following things on your Mac:
Choose Apple menu 
in the sidebar. (You may need to scroll down.)
Click Transfer or Reset.
Click Erase All Content and Settings.
In Erase Assistant, enter your administrator information, then click Unlock.
Review the list of items to be removed in addition to your content and settings.
If your Mac has multiple user accounts, click
next to your Mac user name to review the items.
Click Continue, then follow the onscreen instructions.
When the erase process is complete, your Mac displays “Hello” on the screen. The Mac can now be set up for a new user.
If you've just reset your Mac or bought a new one, the setup assistant will greet you. To get to the desktop as quickly as possible, skipping logins and optional steps:
Once you complete these steps, you will arrive at the macOS desktop.
The Terminal is a powerful tool. You can launch applications directly from it using the open command. Here are commands to open some common applications:
open -a Safari
open -a "Clock"
open -a TextEdit
open -a "Activity Monitor"
Note that quotes are needed around application names that contain spaces, like "Clock" and "Activity Monitor".
Using open -a [Application Name] is a quick way to launch applications without needing to click icons in the Dock or Applications folder. Happy exploring! 🎉
