  • Repeat this for every paired device

Perform A Factory Reset

How do I do a factory reset on my MacBook?

In order to factory reset your MacBook, you need to put the computer into recovery mode. This will erase all of your data from the system. Then, MacOS will be reinstalled.
  • If you want to enter recovery mode, restart your Mac and immediately press and hold Command-R
  • When you see the Apple logo appear, you can release the keys
Then, the MacOS Utilities window will appear. After choosing Disk Utility, click Continue. You’ll need to select your startup disk; it’s probably named Macintosh HD (or something similar) unless you took the time to rename it

Click Erase at the top of the Disk Utility window. You’ll be asked to fill out three fields:

  • Name: You’re renaming the system; if you want to keep things simple, just stick with Macintosh HD
  • Format: If your computer has a mechanical hard drive and is slightly older, you should probably choose Mac OS Extended (Journaled); if you have a newer solid-state drive in your MacBook, choose APFS
  • Scheme: Select GUID Partition Map

Finally, click Erase. Wait for everything to wrap up and quit Disk Utility.

  • You’ll be returned to the MacOS Utilities window
    • If you’re not, restart your Mac one more time and hold Command-R while it boots
  • From the Utilities window, click Reinstall MacOS; follow the provided instructions in order to install the operating system

You should be greeted by the Setup Assistant after reinstallation; you can quit, shut down your Mac, and send it off for a fresh start with a new owner.

Wiping and performing a factory reset on your MacBook is that simple! In many cases, the next appropriate step would be to use a USB file shredder or another similar tool to help make sure data is erased for good. Now that you know how to wipe a MacBook, you may have a few other questions. Let’s take a look.

Can I Factory Reset My MacBook Instead Of Wiping It?

The flaws of using a factory reset to “wipe” your MacBook

Factory resets are a great way to get started on prepping a MacBook for sale, donation, or recycling. They’re not a total solution to protecting your privacy, though. Factory resets only delete things locally on a computer; they’re not always sufficient for wiping personal files.

  • With a factory reset, drive erasure only happens at a local level; information in SIM and on SD cards is preserved 

Perhaps the greatest risk of relying on a factory reset is the false sense of security that it can create. Performing a factory reset on your MacBook will help keep data safe temporarily. It doesn’t actually protect all sensitive information and doesn’t contribute to a healthy security culture.

It’s important to have another layer of security to keep data safe. Whether you’re an individual or a corporation, compromised information and images are never a good thing.
