Resetting your MacBook wipes your data and reinstalls macOS. It’s the right move if you’re selling or giving it away, fixing stubborn software issues, or starting fresh.
Below is a clean, step-by-step guide. Pick the path that matches your Mac and macOS version.
Before you reset
1) Back up your stuff
Use one of these so you don’t lose files:
Time Machine (external drive)
- Plug in an external drive.
- Apple menu → System Settings/Preferences → Time Machine.
- Select your backup disk → Back Up Now.
iCloud Drive (space permitting)
- Apple menu → System Settings/Preferences → Apple ID → iCloud.
- Make sure iCloud Drive is on.
- In Options, include Desktop & Documents if you want them synced.
- Wait for upload to finish.
Tip: If you want a full clone, tools like SuperDuper! or Carbon Copy Cloner can do that.
2) Sign out and remove locks
This prevents Activation Lock issues for the next user.
- iCloud / Find My
- Apple menu → System Settings/Preferences → Apple ID.
- Turn off Find My Mac.
- Click Sign Out.
- Music / TV / Books (deauthorize)
- Open any one (Music/TV/Books).
- Menu bar: Account → Authorizations → Deauthorize This Computer.
- Messages
- Open Messages → Settings/Preferences → iMessage → Sign Out.
3) Optional: unpair Bluetooth devices
Helpful if someone else at home will use the Mac.
- System Settings/Preferences → Bluetooth → remove devices (× → Remove).
4) Optional: reset NVRAM (older Intel Macs)
- Shut down.
- Turn on and immediately hold Option + Command + P + R for about 20 seconds, then release.
If your Mac runs macOS Monterey or later and supports Erase All Content and Settings
Many Apple silicon and T2-chip Intel Macs have this faster option.
- Apple menu → System Settings (Ventura or later) → General → Transfer or Reset → Erase All Content and Settings.
On Monterey: Apple menu → System Preferences, then from the menu bar choose Erase All Content and Settings. - Follow the prompts:
- Enter your Mac login password.
- Sign out of your Apple ID when asked.
- Review what will be erased.
- Confirm Erase All Content & Settings.
- The Mac restarts and shows Activate Mac or the setup screen.
- If you’re selling or gifting it: when the welcome screen appears, press Command + Q → Shut Down. You’re done.
If your Mac doesn’t support the quick erase (older method for any Mac)
You’ll erase the disk in Recovery and reinstall macOS.
Enter Recovery
- Intel Macs: Restart and immediately hold Command + R until you see the Apple logo.
- Apple silicon (M-series): Shut down. Press and hold the power button until Loading startup options appears → Options → Continue.
Erase the disk
- In macOS Utilities, choose Disk Utility → Continue.
- Select your internal disk (usually Macintosh HD). If you see Macintosh HD – Data, erase that first.
- Click Erase:
- Format: APFS for SSDs (most Macs).
For very old Macs with spinning drives, use Mac OS Extended (Journaled). - Name it Macintosh HD (or any name you like).
- If shown, use Erase Volume Group.
- Format: APFS for SSDs (most Macs).
- Quit Disk Utility.
Reinstall macOS
- Back in macOS Utilities, choose Reinstall macOS → Continue.
- Follow the on-screen steps. Connect to Wi-Fi if asked.
- After installation, the setup screen appears.
- Selling or gifting? Press Command + Q → Shut Down so the next person gets the fresh setup.
If you can’t log in (forgot password)
You can still reset using Recovery:
- Use the Enter Recovery steps above.
- Erase the disk in Disk Utility.
- Reinstall macOS.
Note: You won’t be able to back up first, so only use this if you accept losing the data.
Quick checklist
- Back up with Time Machine or iCloud.
- Sign out of iCloud, turn off Find My, deauthorize Music/TV/Books, sign out of Messages.
- Optional: unpair Bluetooth devices.
- Use Erase All Content and Settings if available; otherwise use Recovery → Disk Utility → Erase → Reinstall macOS.
- If selling or gifting: stop at the welcome screen and shut down.
That’s it. Your Mac is now clean, safe to pass on, or ready for a fresh start.
