Before You Wipe
Erasing your MacBook deletes everything – files, apps, accounts, settings. Complete these steps first.
Back up your data. Use Time Machine with an external drive, or manually copy important files to an external drive, iCloud, or another cloud service. Go to System Settings, then General, then Time Machine to set up a backup if you haven’t already.
Sign out of iCloud. Go to System Settings, click your name at the top (Apple ID), scroll down and click “Sign Out.” This removes your Mac from your iCloud account and turns off Find My Mac. If you skip this step and sell the Mac, the new owner will be locked out by Activation Lock.
Sign out of iMessage. Open Messages, click Messages in the menu bar, then Settings (or Preferences), click iMessage, then “Sign Out.”
Deauthorize iTunes/Music (if applicable). Open the Music app (or iTunes on older macOS), click Account in the menu bar, then Authorizations, then “Deauthorize This Computer.” You’re limited to 5 authorized computers.
Unpair Bluetooth devices. Go to System Settings, then Bluetooth, and remove any paired devices. This prevents issues when pairing them with a new computer.
Erase and Reset (macOS Ventura and Later)
macOS Ventura introduced a one-click factory reset option that handles everything.
- Go to System Settings, then General, then “Transfer or Reset.”
- Click “Erase All Content and Settings.”
- Enter your Mac password.
- Review what will be removed (iCloud data, Touch ID fingerprints, Apple Pay cards, Find My). Click “Continue.”
- Enter your Apple ID password to sign out of iCloud and turn off Find My Mac.
- Click “Erase All Content & Settings” to confirm.
- Your Mac erases itself and restarts to the setup screen.
This is the easiest method and works on all Macs running macOS Ventura or later with Apple Silicon (M1 and later) or a T2 security chip (2018 and later Intel Macs). The process takes about 5 to 10 minutes.

Erase Using Recovery Mode (Older Macs)
For Macs running macOS Monterey or earlier, or older Intel Macs without a T2 chip, use Recovery Mode.
Apple Silicon Macs (M1 and later):
- Shut down your Mac completely.
- Press and hold the power button until “Loading startup options” appears.
- Click “Options,” then “Continue.”
- Select a user account and enter the password if prompted.
- From the Recovery menu, select “Disk Utility.”
- Select “Macintosh HD” (or your main volume) in the sidebar.
- Click “Erase.” Name it “Macintosh HD,” set format to APFS, and click “Erase.”
- Close Disk Utility. Select “Reinstall macOS” from the Recovery menu and follow the prompts.
Intel Macs:
- Shut down your Mac.
- Turn it on and immediately hold Command + R until the Apple logo or spinning globe appears.
- From macOS Recovery, open “Disk Utility.”
- Select “Macintosh HD” and click “Erase.” Use APFS format for SSDs or Mac OS Extended (Journaled) for HDDs.
- Close Disk Utility. Select “Reinstall macOS” and follow the on-screen instructions.
The macOS reinstallation downloads from Apple’s servers, so you need an internet connection. On WiFi, click the WiFi icon in the menu bar to connect before starting the reinstall. The download and installation takes 30 minutes to over an hour depending on your internet speed.
Secure Erase
On Macs with SSDs (all modern Macs), the standard erase is already secure. SSDs use hardware encryption, and erasing destroys the encryption key, making the data unrecoverable. No additional “secure erase” step is needed.
On older Macs with spinning hard drives (HDDs), the standard erase leaves data technically recoverable with specialized tools. In Disk Utility, click “Security Options” during the erase process and choose a multi-pass overwrite for a more secure deletion. This takes significantly longer but ensures the data can’t be recovered.
Prepare Mac for Sale or Trade-In
After erasing, your Mac shows the setup screen (“Hello” in multiple languages). If you’re selling or giving away the Mac:
- Don’t complete the setup. Leave it at the “Hello” screen so the new owner can set it up with their own Apple ID.
- Make sure Find My Mac is turned off (if you signed out of iCloud before erasing, it’s already off).
- Remove the Mac from your Apple ID devices list: go to appleid.apple.com, sign in, and remove the Mac from your devices.
For Apple Trade-In, Apple handles the data erasure themselves, but it’s good practice to wipe the Mac before sending it in.

Reinstall macOS Without Erasing
If you want a fresh macOS installation without deleting your files (to fix system issues), you can reinstall macOS over the existing installation.
- Boot into Recovery Mode (same steps as above).
- Select “Reinstall macOS” without erasing the disk first.
- Follow the prompts. macOS reinstalls the system files while preserving your user data, apps, and settings.
This fixes corrupted system files and resolves many performance issues without losing your data. It’s a good first step before doing a full wipe if your Mac is having problems.
Troubleshooting
“Erase All Content and Settings” option not available. This feature requires macOS Ventura or later, and a Mac with Apple Silicon or a T2 security chip. If your Mac doesn’t have it, use the Recovery Mode method instead.
Can’t boot into Recovery Mode. On Intel Macs, try Command + Option + R instead of Command + R. This boots into Internet Recovery, which downloads a recovery environment from Apple’s servers. Make sure you have an internet connection. On Apple Silicon Macs, make sure you’re holding the power button long enough (until you see “Loading startup options”).
Disk Utility doesn’t show Macintosh HD. Click “View” in Disk Utility and select “Show All Devices.” Select the top-level drive (not a sub-volume) and erase the entire drive. This usually fixes cases where volumes are corrupted or hidden.
macOS reinstallation fails. Check your internet connection. Try a different WiFi network. If using Internet Recovery, it downloads the macOS version that originally came with your Mac. To install a specific version, create a bootable USB installer from another Mac using Apple’s instructions.
Will wiping my Mac remove the operating system?
Yes. Erasing the disk removes everything including macOS. You need to reinstall macOS after erasing – Recovery Mode provides this option. On Macs with Apple Silicon, the recovery environment is stored on a separate chip and is always available, even after erasing the main drive.
Can I recover data after wiping?
On Macs with SSDs (2012 and later models), data is effectively unrecoverable after erasing because the encryption key is destroyed. On older Macs with HDDs, data recovery is theoretically possible unless you used a secure erase option. This is why backing up before wiping is so important.
How long does it take to wipe a MacBook Pro?
The erase itself takes 5 to 10 minutes. Reinstalling macOS adds another 30 minutes to over an hour depending on your internet speed (Recovery Mode downloads macOS from Apple’s servers). Total: about 45 minutes to 90 minutes from start to seeing the setup screen.
