How To Factory Reset MacBook/iMac Using Erase All Content and Settings
Erase All Content and Settings on Mac, also referred to as the Erase Assistant, is a valuable factory reset option. This useful feature allows Mac users to erase their devices and all their settings, data, and apps and restore them to factory settings safely and efficiently.
1. Tool: Erase All Content and Settings
The “Erase All Content and Settings” tool is only available on macOS versions newer than macOS Ventura and macOS Monterey with Apple silicon or the Apple T2 Security Chip. If you want to factory reset macOS Ventura and Monterey, Erase Assistant is a good tool to use. We will show you how to erase data on Mac using the Erase Assistant with a written tutorial. First, let’s check the macOS version.
For macOS that has the T2 security chip:
Apple's T2 Security Chip is the company's second-generation custom silicon for Mac. The T2 chip provides your Mac with capabilities such as encrypted storage and secure boot, improved image signal processing, and Touch ID data security.
You can utilize the System Information to determine whether your Mac is equipped with this chip:
Step 1. Hold the Option key and click the Apple menu > System Information.
Step 2. Choose Controller or iBridge from the sidebar, depending on the macOS version. Your Mac has the Apple T2 Security Chip if you see the Apple T2 chip.
For macOS that has Apple Silicon:
Apple silicon is a line of system-on-a-chip (SoC) and system-in-a-package (SiP) processors created by Apple Inc. that primarily uses ARM architecture. It serves as the foundation for the majority of new Mac devices.
Use “About This Mac” to determine the version of the Mac operating system that is installed:
Step 1. From the Apple menu, choose About This Mac.
Step 2. The macOS name, such as macOS Monterey or macOS Big Sur, should be followed by the version number. If you require the build number, click the version number to see it.
2. How To Access the Erase All Content and Settings
Before performing the Mac factory resetting, follow the steps below to access the Erase All Content and Settings option on macOS Ventura and macOS Monterey:
For macOS Ventura
Step 1. Select System Settings from the Apple menu.
Step 2. In the sidebar, select General. On the right, press Transfer or Reset. Lastly, click Erase All Content and Settings.
For macOS Monterey
Step 1. Select System Preferences from the Apple menu.
Step 2. From the System Preferences, click Erase All Content and Settings.
3. Steps To Reset Mac To Factory Settings After Choosing Erase All Content And Settings
After selecting Erase All Content and Settings, follow the following steps to reset your Mac to factory settings:
Step 1. Sign in with administrator credentials by an Erase assistant, then click OK. If you're prompted to back up your Mac before resetting it, you can launch Time Machine and back it up to an external storage device. Alternatively, click Continue to proceed without creating a new backup.
Step 2. Tap Continue to allow the removal of your data.
Step 3. Enter your Apple ID password and press Continue to sign out of your Apple ID. To confirm the process, click Erase All Content & Settings.
Step 4. Your Mac restarts with a black screen and a progress bar. If it needs to reconnect to a Bluetooth accessory, such as a keyboard or mouse, you may be prompted to do so. If the accessory does not connect within 30 seconds, turn it off and on again. Activate your Mac by connecting to a network, then select Restart. After restarting your Mac, a setup assistant walks you through the setup process.
How To Factory Reset MacBook/iMac Without Erase All Content and Settings
The Erase All Content and Settings feature doesn't function on some Mac devices because it is only available in macOS Monterey or later and only on Mac devices equipped with Apple silicon or the Apple T2 Security Chip. However, the Erase All Content and Settings feature is not the only way to factory reset your Mac. You can factory reset your Mac without a password using the following steps:
Step 1: Cancel or transfer AppleCare coverage
You can cancel or transfer your AppleCare plan if your Mac is covered by one. Just follow the step-by-step instructions below.
Cancel the AppleCare plan
If you paid for AppleCare in advance, you must contact Apple to cancel it and receive a refund. Before the process, make sure you have the following items on hand:
- The AppleCare contract number
- Your MacBook Pro's serial number
- Your purchase receipt
Do you already have these? Now, proceed as follows.
1. Go to the Support page, then select Hardware Coverage, followed by Other Hardware Coverage Topics. Click Cancel or request a refund for an AppleCare plan.
2. Under See your support options, click Continue. You must first sign in before being shown the available options.
Once you've reached an Apple support representative, inform them that you want to cancel your AppleCare plan. The refund policies associated with this method are difficult to grasp. It largely depends on how many days have passed since the purchase.
Transfer the AppleCare plan to the new owner
You can transfer your AppleCare plan to the new owner if you sell or donate away your Mac device. Follow the steps below for the right process:
1. Sign into My Support to obtain the AppleCare agreement number, the device's serial number, and proof of coverage for the AppleCare plan. Locate the device's original sales receipt. Then, obtain the new owner's name, address, email address, and phone number.
2. Contact Apple Support.
Some AppleCare plan types and some countries or regions may not allow you to transfer an AppleCare plan to a new owner. Review the applicable AppleCare Terms and Conditions for more information. Check your coverage if you need to know which plan you have.
Step 2: Back up or transfer your files
Before you do anything, make a backup or clone of your Mac. It is because, as you might expect, restoring a Mac to factory settings erases all data stored on the machine.
An important reminder: Don't use iCloud to sync all our Apple devices. Yes, you can recover everything you need from the cloud, but if the Mac is completely wiped out, the data for one non-Apple app you used wasn't in the cloud. It is an easy mistake to make in these days of working primarily in the cloud! Sadly, you cannot yet back up your entire Mac to iCloud.
Fortunately, backing up your Mac is simple if you have an external hard drive. You can easily back up your Mac using Time Machine software. The best part about backing up with Time Machine is that it makes it extremely simple to transfer your data to a new Mac afterward. Alternatively, you back up your important files using effective data backup software.
Step 3: Sign out of iTunes
If you're using macOS Catalina or later, you can skip this step because Apple's latest operating system for the Mac lineup, macOS Catalina, has no more iTunes available.
For users who have macOS below Catalina, follow the step to sign out of your iTunes:
1. Choose Account > Authorizations > Deauthorize This Computer from the iTunes menu bar.
2. Click Deauthorize after entering your Apple ID and password.
Step 4: Sign out of iCloud
Like the Deauthorization process, the next step is to disable iCloud. It is essential to remove all personal information from your device before selling it. To turn off all iCloud information. To proceed, follow the instructions below.
For macOS Ventura or later:
1. Go to the Apple menu > System Settings.
2. Click your Apple ID in the sidebar. Scroll down and click Sign Out.
For macOS Monterey, macOS Big Sur, or macOS Catalina:
1. Choose Apple menu > System Preferences.
2. Click Apple ID.
3. In the sidebar, select Overview, then click Sign Out.
For macOS below Catalina:
1. Select Apple menu > System Preferences.
2. Click iCloud, and finally click Sign Out.
When asked if you want to keep a copy of your iCloud data on this Mac, say “yes” because you will erase your Mac later. Your iCloud data remains in iCloud and on other Apple ID-enabled devices.
Step 5: Sign out of iMessage
The next Apple built-in application that you should sign out of is iMessage. The steps are as follows:
1. Open iMessage and select Messages from the main menu. From the drop-down menu, select Preferences.
2. Select the iMessage account and click Sign out.
Step 6: Unpair Bluetooth devices (Optional)
You can unpair a Bluetooth keyboard, mouse, or device you intend to keep paired with your Mac. This optional step is especially important if you pass your Mac on to someone close to the Bluetooth range, as any Bluetooth device previously paired with your old Mac may reconnect to the old one.
If you're using a Mac without a built-in keyboard or trackpad, you'll need to connect a USB keyboard and mouse to finish the process.
1. Unpair a Bluetooth device by going to the Apple menu > System Settings (or System Preferences) and clicking Bluetooth.
2. Select the device you want to unpair, then click Disconnect or Remove (x).
Step 7: Erase your Mac
This step does not work on Mac computers that use Apple silicon. You can erase an Intel-based Mac with Disk Utility. But before doing this, ensure a backup of any files you want to keep, as erasing your Mac deletes all of its files permanently.
1. Turn on your Mac, then press and hold the Command (⌘) and R keys until you see an Apple logo. If prompted, enter your administrator password. Then, select Disk Utility and press Continue.
2. Select Macintosh HD and click Erase. Then, enter the following information:
- Name: Macintosh HD
- Format: APFS or Mac OS Extended (Journaled)
Select Erase Volume Group. If you don't see this button, click Erase instead.
Step 8: Reinstall macOS
To reinstall the Mac operating system, use macOS Recovery.
1. Start from the macOS Recovery partition, and ensure your Mac is connected to the internet. Depending on whether you're using a Mac with Apple silicon or Intel Processor, proceed as follows:
- Mac with Apple silicon
Turn on your Mac and hold the power button until the startup options window appears. Click Options, then click Continue.
- Intel Processor
Turn on your Mac and immediately hold Command (⌘) - R until you see the Apple logo. If you're prompted to select a user, click Next and enter their administrator password.
2. Data on your Mac is not erased when you reinstall macOS. Select Reinstall macOS from the utility window in macOS Recovery to begin the installation, then click Continue and follow the onscreen instructions.
- To unlock the disk, enter your sign-in password to your Mac.
- If the installer does not recognize your disk or says it cannot install on your computer or volume, you may need to erase it first.
- If the installer prompts you to install on Macintosh HD or Macintosh HD - Data, select Macintosh HD.
- Allow your Mac to finish installing without putting it to sleep or closing it.
*After you erase and reinstall macOS, your Mac reboots to a setup assistant. Rather than continuing setup, click Command-Q to shut down.
Step 9: Reset NVRAM and shut down
Resetting the NVRAM is another way to ensure that none of your settings remain on the Mac. The NVRAM is a small portion of your Mac's memory to store settings. Resetting it clears your user settings and restores any security features you may have changed.
To reset the NVRAM, follow these steps:
1. Turn off your Mac.
2. Turn on your Mac, then click and hold the following four keys simultaneously: Option, Command, P, R. After around 20 seconds, release the keys, and your Mac may appear to restart.
When your Mac has finished booting up, you may need to adjust any reset system settings. Your Mac returns to the setup assistant. To quit the Mac in its original state, tap Command-Q to shut down rather than continue setup.
