Reformatting or wiping a MacBook Pro hard drive allows you to erase all of the data and settings on the drive and restore it to the original factory condition. This can be useful if you are selling or giving away your MacBook, want to reinstall the operating system from scratch, or are trying to resolve hard drive issues.
Reformatting completely erases the contents of the drive, so be sure to back up any important files, photos, etc. before proceeding. Once wiped, the hard drive will be empty and you’ll have to reinstall macOS to use your MacBook again.
When would you need to reformat a MacBook Pro hard drive?
Here are some of the most common reasons for reformatting a MacBook Pro’s hard drive:
Before selling or gifting your MacBook
Reformatting the drive erases all of your personal data and custom settings. This is important to do for privacy reasons before passing your MacBook on to a new owner.
Troubleshooting hard drive issues
If your MacBook is having hard drive errors or problems, reformatting the drive entirely may help resolve them. This essentially gives you a fresh start.
Before reinstalling macOS
If you need to reinstall macOS due to software issues or failures, it’s generally recommended to reformat the hard drive first before reinstalling the operating system.
Switching to a new hard drive
When replacing the existing hard drive in your MacBook with a new one, you’ll need to reformat the new drive before you can use it.
How to reformat a MacBook Pro hard drive
There are a couple different ways to reformat a MacBook Pro’s hard drive. Let’s go over the options:
1. Use Disk Utility
Disk Utility is an application included with macOS that provides tools for managing disks and drives. Here’s how to use it to reformat a drive:
- Connect your MacBook Pro to AC power. Reformatting and reinstalling macOS can take a while, so you want to make sure you don’t run out of battery during the process.
- Back up any files you want to keep. Reformatting will erase everything.
- Restart your Mac and immediately press and hold Command + R. Keep holding until you see the Apple logo or a spinning globe. This will boot you into macOS Recovery.
- When the macOS Utilities window appears, select Disk Utility.
- Click Continue to proceed.
- In the sidebar, select the volume you want to reformat, which is typically named “Macintosh HD”.
- Click the Erase button near the top of the window.
- Enter a name for the drive.
- Select a format – APFS is recommended for most Macs using modern versions of macOS.
- Click Erase to begin reformatting the hard drive. This may take several minutes.
- When done, quit Disk Utility.
Your MacBook Pro’s hard drive is now wiped clean and empty, ready for macOS to be reinstalled or for a new owner.
2. Use macOS Recovery
macOS includes a recovery environment that you can access over the internet and has options to reformat a drive. Here’s how:
- Connect to AC power and backup your files, just like with the Disk Utility method.
- Restart your MacBook Pro and immediately press and hold Command + R. Keep holding until you see the recovery environment load.
- Select Disk Utility from the macOS Utilities window, then click Continue.
- In Disk Utility, select the volume to reformat, click Erase, name it, and select the format.
- When done, click on the Disk Utility menu and select Quit Disk Utility.
- In the macOS Utilities window, select Reinstall macOS.
- Follow the prompts to reformat the drive and reinstall macOS.
Using the macOS Recovery environment can be a simpler and more integrated way to reformat the hard drive. Just be sure to have an internet connection.
3. Use Internet Recovery
If your MacBook Pro no longer has a working Recovery partition or macOS installer, you can still reformat the drive by using Internet Recovery:
- Disconnect any external devices besides the power adapter.
- Restart your MacBook Pro and immediately press and hold Option + Command + R. Keep holding until you see a spinning globe.
- Your Mac will boot into internet recovery mode after a few moments. Select Disk Utility and click Continue.
- In Disk Utility, reformat the drive following the same steps covered above.
- When done, quit Disk Utility then choose Reinstall macOS from the menu bar to begin reinstalling the OS over the internet.
Internet Recovery requires an internet connection and can be slower than other options, but works if you cannot access the standard Recovery options.
How to Verify the Drive is Reformatted
Once you’ve completed the reformatting process via one of the methods above, here are a couple ways to verify that the hard drive is wiped and ready to go:
Reboot to the macOS installer
After formatting the drive, reboot back to the macOS installer (using macOS Recovery or Internet Recovery). At the installer screen:
- Select your language then click Continue.
- Go to Utilities > Disk Utility in the menu bar.
- Select the drive and check that it no longer contains any partitions or data.
- Also check that it has the name you gave it and the format is what you selected.
This confirms the reformatting process completed properly.
Check Disk Utility
You can also just reboot your MacBook normally. When back in macOS:
- Open Disk Utility.
- Select the hard drive and inspect it.
- Check that it appears empty with no data and the expected name and format.
If so, your reformat is complete!
What to do after reformatting your MacBook Pro
Once you have wiped your MacBook Pro’s hard drive, here’s what to do next:
Reinstall macOS
With the drive emptied, you’ll need to reinstall macOS to make your Mac functional again. Follow the prompts after booting from Recovery to reinstall the latest macOS version.
Restore your data
Use your backup files to transfer any important documents, photos, music, and other files back onto your MacBook. Be sure to get your data off the backup drive before reformatting.
Reconfigure settings
Adjust preferences and settings like your desktop image,mouse/trackpad, Sidecar etc. to your liking. You’ll have to set up profiles and accounts again as well.
Install applications
Finally, you can install apps like web browsers, productivity suites, games, etc. to have a fully functional MacBook Pro again!
FAQs about reformatting a MacBook Pro hard drive
Here are answers to some common questions about reformatting a MacBook Pro’s hard drive:
Is reformatting the same as wiping a MacBook Pro?
Yes, reformatting essentially wipes or erases all of the data from the MacBook Pro’s hard drive. The terms reformat and wipe can be used interchangeably when referring to completely erasing a drive.
Will reformatting improve MacBook Pro performance?
Possibly! Reformatting can help resolve errors and file system damage that may be causing performance issues. Removing all files and starting fresh improves available storage space as well.
Can you recover lost files after reformatting?
Unfortunately, no. Once a drive is reformatted, all previous files and data are permanently erased. This is why it’s absolutely essential to back up what you want to keep before wiping the drive.

How can you reformat without losing everything?
You’ll need to back up your files before reformatting. Copy important documents, photos, music, and other data you want to keep to an external hard drive or cloud storage. After reformatting, transfer the files back from backup.
Conclusion
Reformatting a MacBook Pro provides a clean slate, resolving hard drive issues and preparing it for a new owner. Use Disk Utility or the macOS Recovery options to wipe the drive. Be absolutely certain to back up your data first! With the contents secure and the drive emptied, reinstall macOS to get your freshly formatted MacBook Pro up and running once again.
