How to Get Your MacBook Ready to Sell

Getting a MacBook ready to sell means protecting your files, unlinking your accounts, erasing your personal data, and leaving the computer ready for its next owner. Before you begin, make sure your important files are backed up and you have the Apple Account password and any other credentials you may need; keep the Mac connected to power during the process.

What You’ll Need

A backup drive or enough iCloud or other cloud storage for files you want to keep.
Your Apple Account password and, if applicable, your Mac administrator password.
A reliable internet connection and the MacBook’s power adapter.
Another device to check your backup and, if needed, manage your Apple Account.

Step-by-Step

Check the Mac and sale details. Find the model and basic specifications from the Apple menu > About This Mac, and note them for your listing. Check that the display, keyboard, trackpad, ports, Wi-Fi, and charger work. Photograph the condition honestly, including scratches or other damage. Do not publish the Mac’s serial number; provide it privately only when there is a good reason.
Back up what you want to keep. Use Time Machine with an external drive, copy files to another storage device, or use a cloud service. Open a few files from the backup, and confirm that important folders, photos, and any work stored outside your usual folders are included. Browser bookmarks, password managers, app libraries, and local email archives may need separate checks. Do not assume that signing out or erasing the Mac creates a backup.
Transfer or deactivate software as needed. Check apps that limit how many computers can use a license, and follow the app maker’s sign-out or deactivation instructions. If you use a password manager, authenticator, or specialized work software, make sure you can access it on another device before wiping the Mac. Keep any recovery codes in a secure place.
Check whether Erase All Content and Settings is available. On a Mac with Apple silicon, or an Intel Mac with the Apple T2 Security Chip, running macOS Monterey or later may offer this option. Open the Apple menu > System Settings (or System Preferences) and look for Erase All Content and Settings in the menu bar under the app name. If it is available, use it and follow the prompts. The Mac may ask for an administrator password and Apple Account password. Read each confirmation carefully: erasing removes local data and settings.
If that option is unavailable, sign out and erase through macOS Recovery. First sign out of iCloud or your Apple Account in System Settings (or System Preferences), and sign out of Messages if you use it. In older macOS versions, also use the iTunes account menu to deauthorize the Mac if that option applies. Shut down the Mac. To open Recovery on Apple silicon, press and hold the power button until startup options appear, then choose Options. On an Intel Mac, turn it on and immediately hold Command-R until Recovery appears. In Recovery, open Disk Utility, select the startup volume or volume group, and use Erase. Choose the format and scheme offered for the selected disk; do not erase external backup drives. If the volume group offers an option to erase it, use that rather than erasing unrelated disks. Quit Disk Utility when finished.
Reinstall macOS when you used Recovery. From the Recovery utilities window, choose Reinstall macOS and follow the onscreen instructions. Keep the Mac connected to power and the internet. When setup appears after installation, do not enter your personal account or create an account for the buyer. Press Command-Q and choose Shut Down, or follow the on-screen shutdown option, so the next owner sees the welcome setup screen.
Confirm it is ready to hand over. Start the Mac only far enough to confirm the welcome or setup screen appears; do not complete setup. If you still see your desktop, personal account, or files, the Mac was not erased. Check your Apple Account device list from another device and remove the Mac only after the erase is complete, if it remains listed. Include the charger and any accessories promised in the sale, and remove labels or personal items you do not intend to leave.

Common Mistakes

Erasing before checking the backup: Once erased, local files may be difficult or impossible to recover. Verify the backup first.
Just deleting files or reinstalling macOS: Those actions alone do not reliably remove all personal data or unlink account-related protections. Use Erase All Content and Settings when available, or erase the startup disk in Recovery and reinstall.
Leaving Find My or Activation Lock enabled: The buyer may be unable to activate the Mac. Sign out of your Apple Account as part of the erase process and make sure the device is no longer tied to your account.
Setting it up again after erasing: Signing in or creating a user account adds personal information back. Stop at the welcome screen and shut down.
Wiping the wrong disk: In Disk Utility, identify the internal startup disk carefully. Leave backup drives and other external storage untouched.

Tips

Keep a note of the Mac’s model, memory, storage, and condition for your listing, but do not include account details or passwords.
Remove the Mac from trusted-device lists only after you know your backup is safe and the erase is complete. If you use other Apple devices, check that they still have access to your account and recovery methods.
Be accurate about battery condition and cosmetic wear. Avoid promising a specific battery runtime; actual use and settings affect it.
Keep the power adapter nearby during erasing and installation. Do not close the lid or interrupt power while macOS is being reinstalled.

Troubleshooting

Erase All Content and Settings is missing: The Mac or its macOS version may not support it. Check About This Mac for the model and macOS version, then use the sign-out and Recovery method. If you are unsure which disk to erase, stop and check Apple’s instructions for that exact Mac model before proceeding.
You cannot sign out or do not know the Apple Account password: Do not hand over the Mac while it remains linked to your account. Recover access through Apple’s account-recovery process or contact Apple Support. Do not share your password with a buyer.
The Mac asks for another person’s account during activation: It may still be associated with a previous owner. Ask that owner to remove it from their account; do not try to bypass Activation Lock. If you bought the Mac second-hand and cannot reach the owner, contact Apple Support with proof of purchase.
Recovery does not load or installation fails: Connect to power and a stable internet connection, restart, and try Recovery again. On an Intel Mac, use Command-R at startup; on Apple silicon, hold the power button for startup options. If the internal disk is missing or reports errors, stop repeated erase attempts and contact Apple Support or a qualified repair provider.
Your backup is incomplete: If you have not handed over or erased the Mac yet, copy the missing files and verify them. If the Mac has already been erased, check other devices and cloud backups; recovery is not guaranteed.

Frequently Asked Questions

Do I need to remove the MacBook from Find My before erasing it?
Follow the erase prompts and sign out of your Apple Account. Confirm afterward that Find My and Activation Lock no longer tie the Mac to your account.

Should I leave macOS installed?
Yes. If you erase using Recovery, reinstall macOS, then stop at the welcome screen. Erase All Content and Settings usually returns the Mac to setup automatically.

Can I sell a MacBook that will not turn on?
You cannot confirm that its data has been erased if it will not start. Do not assume removing the drive or signing out remotely has erased it; get model-specific advice from Apple Support or a qualified repair provider, and disclose the fault.

Will erasing the Mac delete my cloud files?
Erasing the Mac removes local data, but deleting synced files while signed in can also delete them from cloud storage and other devices. Back up first and avoid manually deleting synced files.

How can I tell the erase worked?
The Mac should display the initial welcome or setup screen without showing your user account or desktop. Do not complete setup just to check.

What if I already gave the Mac to the buyer while it is still linked to me?
Contact the buyer and arrange to complete the proper sign-out and erase process. Remove the Mac from your account only through Apple’s normal device-management steps; never give out your password.
