Selling your MacBook? Before it goes to a new owner, you need to wipe your personal data, sign out of Apple services, and restore it to factory settings. The steps depend on whether your Mac uses Apple Silicon (M1 and later) or an older Intel chip. This guide covers both.
Quick Answer
On an Apple Silicon Mac (2020 or later) running macOS Monterey or newer, go to System Settings > General > Transfer or Reset > Erase All Content and Settings. That single step handles everything. On older Intel Macs, you need to sign out of Apple services manually, then boot into Recovery Mode to erase the drive and reinstall macOS. Full steps for both methods below.Ready to list your MacBook? Shop or sell on Swappa’s MacBook marketplace.
Which Reset Method Do You Need?
The right process depends on your Mac model and macOS version.
| Mac type | macOS required | Method |
|---|---|---|
| Apple Silicon (M1, M2, M3, M4) | Monterey 12.0.1 or later | Erase All Content and Settings |
| Intel Mac with T2 chip (2017–2020) | Monterey 12.0.1 or later | Erase All Content and Settings |
| Intel Mac without T2 chip (pre-2017) | Any | Manual sign-out + Recovery Mode |
| Any Mac on macOS Big Sur or earlier | macOS Big Sur or earlier | Manual sign-out + Recovery Mode |
Not sure which chip your Mac has? Go to Apple menu > About This Mac. If it shows an M-series chip (M1, M2, etc.), you have Apple Silicon. If it shows Intel Core, you have an Intel Mac.
Method 1: Erase All Content and Settings (Apple Silicon and T2 Macs)
This is the fastest, most thorough reset available. It signs you out of iCloud, removes your Apple ID, erases all data, and reinstalls macOS in one step.
Back Up Your Data First
Before erasing, back up anything you want to keep.
- Time Machine: Connect an external drive and open System Settings > General > Time Machine to run a backup.
- iCloud: Make sure any documents, photos, or app data you want to keep have finished syncing to iCloud.
Run Erase All Content and Settings
- Open System Settings (or System Preferences on older macOS versions).
- Go to General > Transfer or Reset.
- Click Erase All Content and Settings.
- Enter your Mac password when prompted.
- Review the list of items that will be removed, then click Continue.
- Enter your Apple ID password to disable Activation Lock and sign out of iCloud.
- Click Erase All Content and Settings to confirm.
The Mac will erase, reinstall macOS, and restart to the setup screen. Stop there. Do not complete the setup. The new owner will set it up with their own Apple ID.
Method 2: Manual Wipe for Older Intel Macs
If your Mac does not support Erase All Content and Settings, you need to sign out of Apple services manually before erasing the drive.
Step 1: Back Up Your Data
Use Time Machine or copy important files to an external drive or cloud storage before continuing.
Step 2: Sign Out of Apple Services
Sign out of iCloud
- Open System Settings (or System Preferences on older macOS).
- Click your Apple ID / name at the top.
- Scroll down and click Sign Out.
- Choose to keep or remove a copy of your iCloud data on this Mac (your copy in iCloud is not affected).
- Enter your Apple ID password and click Turn Off.
Signing out of iCloud automatically disables Find My Mac and removes Activation Lock. This is the most important step. A MacBook with Activation Lock still enabled is unusable to the new owner.
Sign out of iMessage
- Open Messages.
- In the menu bar, go to Messages > Settings (or Preferences on older macOS).
- Select the iMessage tab.
- Click Sign Out.
Sign out of Music (formerly iTunes)
If you have authorized this Mac to play purchased Apple content, deauthorize it before selling.
- Open the Music app.
- From the menu bar, go to Account > Authorizations > Deauthorize This Computer.
- Enter your Apple ID and password.
- Then go to Account > Sign Out.
Sign out of other apps
Deauthorize any third-party software tied to your machine, such as Adobe Creative Cloud or Microsoft Office, using each app’s account settings.
Step 3: Boot into Recovery Mode
On Intel Macs:
- Restart your Mac.
- Immediately hold Command + R and keep holding until you see the macOS Utilities screen.
On Apple Silicon Macs running an older macOS without Erase All Content and Settings:
- Shut down your Mac.
- Hold the power button until you see “Loading startup options.”
- Select Options, then click Continue.
Step 4: Erase the Drive with Disk Utility
- In macOS Utilities, select Disk Utility and click Continue.
- In Disk Utility, select your startup disk from the sidebar. It is usually named Macintosh HD.
- Click Erase in the toolbar.
- In the dialog, set the Format:
- APFS for any Mac with an SSD (most Macs from 2017 onward)
- Mac OS Extended (Journaled) only for older Macs with a spinning hard drive
- Leave the Scheme as GUID Partition Map.
- Click Erase and wait for it to finish.
- Quit Disk Utility.
If your Mac shows both Macintosh HD and Macintosh HD – Data, erase the Data volume first, then erase Macintosh HD.
Step 5: Reinstall macOS
- In macOS Utilities, select Reinstall macOS and click Continue.
- Follow the prompts to select your erased disk and begin installation.
- Your Mac will restart once or twice during installation.
- When the setup assistant appears, stop. Do not complete the setup. Hold Command + Q and choose Shut Down.
The Mac is now ready for its new owner.
Before You Hand It Over: Activation Lock Checklist
Activation Lock is the single most common reason a used MacBook sale goes sideways. A buyer who receives a Mac with Activation Lock enabled cannot use it. Verify the following before shipping:
- Find My is disabled: Confirmed during iCloud sign-out in Method 2, or handled automatically in Method 1.
- Your Apple ID is no longer linked: Go to appleid.apple.com, sign in, and confirm the Mac no longer appears under your devices.
- No MDM enrollment: If this was a work Mac, contact your IT department to unenroll it before selling.

FAQ
Do I need to back up my MacBook before a factory reset?
Yes. A factory reset permanently erases everything on the drive. Back up to Time Machine or an external drive before starting. iCloud sync is not a substitute for a full backup if you have files not stored in iCloud.
What happens to Activation Lock when I erase my MacBook?
If you sign out of iCloud before erasing (or use Erase All Content and Settings, which does this automatically), Activation Lock is removed. If you skip the sign-out step, your Apple ID stays linked and the new owner will be locked out.
Can I reset my MacBook without the Apple ID password?
No. You need your Apple ID password to sign out of iCloud and disable Activation Lock. Without it, the Mac remains locked to your account after the reset. Contact Apple Support if you have lost access to your Apple ID.
Which macOS format should I choose when erasing: APFS or Mac OS Extended?
Use APFS for any Mac with an SSD, which includes all MacBooks from 2017 onward. Mac OS Extended (Journaled) is only needed for older Macs with mechanical hard drives.
Should I complete the setup after reinstalling macOS?
No. Stop at the setup screen and shut down. Let the new owner complete setup with their own Apple ID. If you complete setup yourself, you create another account that has to be removed.
How do I reset an Apple Silicon Mac without a password?
If you have forgotten your login password, Apple Silicon Macs allow you to recover using your Apple ID during startup. Hold the power button until startup options appear, then use the recovery options. Contact Apple Support for help with locked accounts.
Conclusion
A proper factory reset protects your data and gives the next owner a clean machine to set up as their own. On Apple Silicon Macs, the whole process takes a few minutes with Erase All Content and Settings. On older Intel Macs, plan for an hour to sign out, erase, and reinstall macOS.
Once your MacBook is wiped and verified clear of Activation Lock, it is ready to sell. Browse current MacBook listings on Swappa to see what comparable models are going for, or list yours and reach buyers who are ready to purchase.
