How to Factory Reset a Mac Mini

To factory reset a Mac mini, back up anything you need, erase the Mac through Erase All Content and Settings or macOS Recovery, and then reinstall or activate macOS. The correct steps depend on whether the Mac mini has Apple silicon or an Intel processor.

What should you do before factory resetting a Mac mini?

A factory reset Mac mini process permanently removes personal files, accounts, settings, and installed apps. Complete these checks before erasing the computer:

• Back up documents, photos, passwords, and other files you want to keep. You can use Time Machine or copy important files to separate storage.
• Confirm that the backup opens and contains the expected files before continuing.
• Sign out of iCloud and turn off Find My Mac if macOS does not handle those steps during the erase process. Find My is the Apple feature that enables Activation Lock.
• Disconnect storage devices that should not be erased.
• Connect the Mac mini to power, a display, a keyboard, and a reliable internet connection.
• Note the installed macOS version. Select the Apple menu and choose About This Mac to find it.
• Check whether the Mac mini uses Apple silicon or an Intel processor. About This Mac shows either a Chip entry for Apple silicon or a Processor entry for Intel.

If the Mac mini is being sold or given away, do not restore your backup after erasing it. Leave the computer at Setup Assistant so the next owner can complete setup.

How do you erase a Mac mini with Apple silicon using macOS Recovery?

macOS Recovery is a built-in startup environment used to erase a disk, reinstall macOS, and run repair tools. Use these steps when Erase All Content and Settings is unavailable or the Mac cannot start normally.

1. Shut down the Mac mini completely.
2. Press and continue holding the power button. Release it when the screen shows that startup options are loading.
3. Select Options, then select Continue.
4. Choose an administrator account if prompted, enter its password, and follow the onscreen instructions.
5. Look for Erase Mac or Erase Assistant in the Recovery menus. Follow the prompts to remove user data and settings.
6. If the erase option is unavailable, open Disk Utility, select the internal startup volume, and choose Erase. Use the format and scheme recommended by Disk Utility or Apple’s current instructions.
7. Quit Disk Utility after the erase finishes. Select Reinstall macOS in Recovery and follow the prompts if macOS was not retained automatically.

The Mac mini may restart and require an internet connection for activation. Keep it connected to power throughout the process.

How do you factory reset an Intel Mac mini using macOS Recovery?

An Intel Mac mini normally uses Command-R to open its built-in macOS Recovery system.

1. Restart the Mac mini and immediately hold Command-R until an Apple logo or another startup screen appears.
2. Select a user account and enter the password if requested.
3. Open Disk Utility from the Recovery window.
4. Select View, then Show All Devices, if the internal startup disk is not visible.
5. Select the startup volume or internal disk named in Apple’s current erase instructions. Choose Erase, then confirm the operation.
6. When erasing is complete, quit Disk Utility to return to the Recovery window.
7. Select Reinstall macOS and follow the onscreen instructions. Choose the newly erased internal disk as the installation destination.

Do not interrupt the installation if the screen goes blank or the Mac mini restarts several times. If the Mac is changing owners, stop when Setup Assistant displays its first welcome or country-selection screen.

When can you use Erase All Content and Settings on a Mac mini?

Erase All Content and Settings removes user data and settings while keeping the currently installed operating system ready for setup. It is generally the simplest option when it appears on a supported Mac running a compatible macOS version.

On current macOS versions, open the Apple menu, choose System Settings, select General, choose Transfer or Reset, and then select Erase All Content and Settings. On macOS Monterey, the command may appear in the System Preferences menu after you open System Preferences.

1. Open Erase All Content and Settings.
2. Enter the administrator password when requested.
3. Review any summary of accounts, settings, and data that will be removed.
4. Follow the prompts to sign out of the Apple Account and disable related security features if requested.
5. Confirm the erase and wait for the Mac mini to restart.

If the command does not appear, use the appropriate Apple silicon or Intel Recovery procedure. Its absence can depend on the Mac hardware and installed macOS version.

What should you do after resetting a Mac mini?

Setup Assistant is the sequence of screens that selects the region, network, Apple Account, and other initial settings. What you do next depends on who will use the Mac mini.

• If you are keeping it, connect to Wi-Fi or Ethernet, complete activation, and sign in with your Apple Account when prompted.
• Restore from a Time Machine backup during Setup Assistant if you want your saved accounts, apps, and files returned.
• If you prefer a clean setup, finish Setup Assistant and copy back only the files you need.
• If someone else will receive the Mac mini, do not enter your Apple Account or create a new user. Shut it down at the first Setup Assistant screen.

What can you do when a Mac mini reset gets stuck?

If the Mac mini stays on a progress bar for an unusually long time, keep it connected to power and check whether the bar is still moving. If there is no change, follow Apple’s official startup guidance before forcing another restart, because interrupting an active installation can leave macOS incomplete.

If Recovery cannot find Wi-Fi, move closer to the router, verify the network password, or use a wired Ethernet connection when available. Networks that require a browser sign-in may not work reliably in Recovery, so try a standard private network.

If Activation Lock appears after the reset, the Apple Account previously linked through Find My must authorize the Mac. Sign in with that account when prompted. If the Mac belonged to someone else, that person must remove the Mac mini from their account; erasing the disk does not bypass Activation Lock.

Where can you get official help if a Mac mini will not reset?

Open {site} and search Apple Support for the exact symptom, such as “Mac starts up to a progress bar,” “start up from macOS Recovery,” or “Activation Lock for Mac.” Match the instructions to the Mac mini’s Apple silicon or Intel processor and its macOS version.

If the reset still fails, use the support options shown by Apple for your location. Have the Mac mini serial number, processor type, macOS version, and any onscreen error message ready, but never share an Apple Account password or verification code.
