Steps you should follow before selling your MacBook Pro

First of all, you have to make sure it's ready to sell. Physically, check if it's in good-looking and sellable condition. Clean the screen and the case, trackpad, and keyboard. Use a microfiber cloth and alcohol-free cleanser.

Apple recommends that you boot the Mac into macOS Recovery and execute this Terminal command: xartutil --erase-all before you sell or give away a MacBook Pro with Touch Bar (which has a Touch ID sensor). We’re not sure what it does, and Apple doesn’t give any explanations, but we suspect it acts to clear the Secure Enclave that stores your fingerprint data. Regardless, it would be wise to follow Apple’s advice.

Apple highlights the additional step in its support guide:


You can clear any information stored by the Touch Bar before you sell or give away your MacBook Pro.

First, start up from macOS Recovery: Hold down Command-R on your keyboard immediately after pressing the power button to turn on your Mac, or immediately after your Mac begins to restart.

When the macOS Utilities window appears, choose Utilities > Terminal in the menu bar. Type this command in Terminal: xartutil --erase-all

Press Return, type yes when asked if you’re sure, and then press Return again. Finally, choose Terminal > Quit Terminal and proceed to the next step."

But you shouldn’t worry if you sold or gave away your MacBook Pro with Touch Bar and didn’t use the Terminal command first, but it won’t hurt to give it a shot if you want to follow Apple’s steps for erasing your MacBook Pro.

It does feel rather un-Apple to type in the Terminal command (it’s not exactly user-friendly even for a Pro machine) and the payoff makes you think ‘okay, that was it?’ but here’s how it looks:
