Are you facing issues with your Mac and feel that resetting the settings might solve the problem? Resetting the settings on your Mac can help resolve various software-related issues and give your system a fresh start. In this tutorial, we will guide you through the process of resetting settings on your Mac.

Before You Begin

Before you proceed with resetting the settings on your Mac, it is crucial to understand that this action will restore your system to its default settings. It will remove all personal preferences, customizations, and network settings. Therefore, it is essential to back up all your important files and data before proceeding further.

Step 1: Shut Down Your Mac

The first step in resetting the settings on your Mac is to shut down the system completely. Click on the Apple menu in the top-left corner of your screen and select “Shut Down”. Wait for a few moments until your Mac turns off completely.

Step 2: Start Your Mac in Recovery Mode

Once your Mac is shut down, press and hold the Command (⌘) + R keys simultaneously and then press the power button. Keep holding down the keys until you see the Apple logo or a spinning globe icon.

Your Mac will now start in Recovery Mode. This mode allows you to perform various troubleshooting actions, including resetting settings.


If you are using a macOS version earlier than OS X Lion 10.7, you won’t have access to Recovery Mode. In that case, you can use a bootable installation disk instead.

Step 3: Access Utilities

In Recovery Mode, select “Disk Utility” from the macOS Utilities window and click “Continue”.

Step 4: Erase macOS

In the Disk Utility window, select your startup disk (usually named “Macintosh HD”) from the left sidebar and click on the “Erase” tab.

Click on the “Format” dropdown menu and choose the appropriate format for your Mac’s startup disk. By default, it is set to “Mac OS Extended (Journaled)”.

Enter a new name for your disk if you wish, and then click on the “Erase” button. This action will erase all data on your Mac’s startup disk.


Make sure you have backed up all important data before proceeding with this step, as it will permanently delete everything on your Mac’s startup disk.

Step 5: Reinstall macOS

After erasing the disk, close Disk Utility to return to the macOS Utilities window. Now, select “Reinstall macOS” and click on “Continue”.

Follow the on-screen instructions to reinstall macOS. This process may take some time, so be patient.

Step 6: Set Up Your Mac

Once macOS is reinstalled, your Mac will restart automatically. You will be guided through the initial setup process, similar to when you first bought your Mac.

Follow the instructions on-screen to set up your language preferences, Wi-Fi network, Apple ID, and other necessary settings.


If you have a Time Machine backup or any other backup of your data, you can restore it during this setup process.


You have successfully reset the settings on your Mac. Your system should now be running with default settings, and any software-related issues you were facing should be resolved.

Remember to reinstall any necessary applications and restore your data from backups to get your Mac back to its previous state.

Resetting the settings on your Mac can be a powerful troubleshooting tool, but it should be used with caution. Make sure to backup your data and understand the consequences before proceeding.

That’s it! You now know how to reset settings on your Mac.
