If you've begun to encounter weird glitches and problems with your MacBook or MacBook Pro that no amount of troubleshooting will solve, it may be time for a fresh start. Here's how to reset a MacBook Pro.

Back Up Your Data Before You Reset Your MacBook Pro

Even if you never plan to use your data again, make sure to back it up, just in case. The last thing anyone wants is to permanently delete something important. MacBook Pro users should use Time Machine to back up your MacBook in case you need to restore your information.

  1. Open Time Machine from the Applications folder on your computer.

  2. Connect an external hard drive to your machine.

    While you can use iCloud to back up your data, you cannot back up the OS or your applications to the cloud.

    Select the drive you want to backup to.
  3. When Time Machine is set up, you can tell it to make automatic backups. You can also back up your computer by selecting "Back Up Now" from the Time Machine menu.

  4. Allow enough time for the backup to complete.

  5. Once the backup is finished, disconnect the external drive.

How to Factory Reset MacBook Pro

Now that you have backed up all of your information, you can begin the process of resetting the MacBook Pro. Before you reset your computer, make sure you have a solid internet connection so you can download the latest version of macOS after the reset. If possible, connect your machine directly to your router or modem.

You should always reset your MacBook Pro to factory settings before selling or disposing of it. Dropping a file into the Trash and emptying it isn't enough, as there are still ways to restore the file later. A factory reset ensures your data is erased from the machine and cannot be recovered.

  1. Shut down your MacBook.

  2. Restart the laptop in Recovery Mode. There are three ways to do this, and they each require a keyboard combination.

    • The first is to hold down Command+R as the MacBook boots up. This option opens the standard version of Recovery Mode and lets you install the latest version of macOS.
    • The second is to hold down Option+Command+R. This command gives you the option to upgrade to the latest version of macOS that is compatible with your machine.
    • The third way is to hold down Shift+Option+Command+R. This combination installs the version of macOS that came with your computer or the closest version available if that OS can no longer be downloaded.

    Regardless of which method you use, keep the keys held down until the Apple logo appears.

  3. In the window that appears, click Disk Utility.

  4. In the Disk Utility window, click View, then click Show All Devices.

    Disk Utliity can show some or all connected devices.
  5. Choose the drive you want to erase. It will likely be titled "Macintosh HD."

  6. Click Erase.

    Select
  7. Quit Disk Utility and return to the previous window.

  8. Click Reinstall macOS.

  9. Follow the steps you see on the screen. Allow sufficient time for the installation to complete.

    This process can take several hours to finish.

  10. When the OS has installed, the machine will restart. After this, you'll be prompted for your Apple ID and username.

  11. If you reset your MacBook Pro in order to sell it, press Command+Q to shut down the machine.
