How to Reset an iPhone Using a Computer

You can reset an iPhone with a computer by connecting the phone to Finder on a Mac or iTunes on Windows or an older Mac, then choosing Restore iPhone. If you cannot enter the passcode, place the iPhone in recovery mode first so the computer can erase and reinstall its software.

A reset erases the iPhone, including its accounts, settings, and locally stored files. You can recover information afterward only if you have a suitable iCloud or computer backup.

When should you reset an iPhone from a computer?

Resetting an iPhone with a computer is useful when you have forgotten the passcode, the device is unavailable or disabled after repeated attempts, or normal on-device settings cannot be opened.

You may also reset an iPhone before giving it to someone else. If you can still use the phone, back it up, sign out of your Apple ID, and turn off Find My before erasing it. If you cannot unlock it, recovery mode can erase it, but it cannot remove Activation Lock or the Apple ID associated with the phone.

What do you need before resetting an iPhone with a computer?

• A Mac using Finder, or a Windows PC or older Mac with iTunes installed and updated.
• A compatible USB cable that can transfer data, not merely charge the phone.
• A stable internet connection so the computer can download the iPhone software.
• Your Apple ID and password for setup after the reset.
• A recent backup if you want to restore your photos, messages, settings, and other information.

Keep the iPhone connected while the software downloads and the restore runs. The process erases the device, so do not begin until you understand what will be removed.

How do you reset an iPhone with Finder on a Mac?

Finder manages connected iPhones on Macs that do not use iTunes. If the iPhone is unlocked and responding, follow these steps:

1. Connect the iPhone to the Mac with a compatible cable.
2. Unlock the iPhone if prompted, select Trust, and enter the passcode. Confirm the trust prompt on the Mac as well.
3. Open Finder and select the iPhone under Locations in the sidebar.
4. Select the General tab, then select Restore iPhone.
5. Confirm that you want to erase the iPhone and restore its software.
6. Leave the iPhone connected while Finder completes the restore and the phone restarts.

If Finder asks whether to back up the iPhone first, create a backup only if you can access the phone and still need its current information.

How do you reset an iPhone with iTunes on a computer?

Use iTunes to reset an iPhone on Windows or on a Mac that still manages iPhones through iTunes.

1. Open iTunes and install any available iTunes update.
2. Connect the iPhone with a compatible USB cable.
3. If requested, unlock the iPhone, approve Trust, and enter its passcode.
4. Select the small device icon near the top of the iTunes window.
5. Open Summary and select Restore iPhone.
6. Confirm the erase and restore, then keep the phone connected until it restarts.

If you are searching for how to reset iPhone on computer, the Restore iPhone command is the key step. Use recovery mode instead if iTunes requests a passcode that you cannot provide.

How do you reset an iPhone when you do not know the passcode?

Recovery mode is a startup state that lets Finder or iTunes reinstall the iPhone software when the normal screen cannot be used. Turn off the iPhone before starting, and have the cable connected to the computer but not yet to the phone.

1. For iPhone 8 or later, including iPhone SE models from the second generation onward, hold the side button while connecting the cable to the iPhone.
2. For iPhone 7 and iPhone 7 Plus, hold the volume-down button while connecting the cable.
3. For iPhone 6s or earlier and the first-generation iPhone SE, hold the Home button while connecting the cable.
4. Keep holding the appropriate button until the recovery-mode screen appears. Do not release it when the Apple logo first appears.
5. In Finder or iTunes, select the iPhone and choose Restore when offered Restore or Update.
6. Wait while the computer downloads the software, erases the iPhone, and reinstalls iOS.

If the download takes long enough for the iPhone to leave recovery mode, let the download finish, turn off the iPhone, and repeat the recovery-mode steps.

People also search for how to reset iPhone without password or computer. Without the passcode, a computer and recovery mode provide the direct method covered here; an eligible iPhone may instead show an on-screen erase option or may be erasable through Find My. None of these methods bypasses Activation Lock.

What should you do after the iPhone reset finishes?

When the Hello screen appears, disconnect the iPhone and begin setup. Choose Set Up as New iPhone for a clean start, or choose an available iCloud or computer backup to restore saved information.

Sign in with the Apple ID previously associated with the iPhone if Activation Lock appears. If you do not know those credentials, use Apple’s account-recovery process or ask the previous owner to remove the device from that owner’s account. Erasing the phone does not remove this protection.

What should you do if the computer does not detect the iPhone?

1. Disconnect and reconnect the cable firmly at both ends.
2. Try another USB port directly on the computer rather than through a hub.
3. Try another compatible data cable if the iPhone charges but does not appear.
4. Restart the iPhone and computer, then reopen Finder or iTunes.
5. Check for macOS, Windows, or iTunes updates.
6. If the phone is locked or disabled, turn it off and enter recovery mode again using the correct button for the model.

If the iPhone still is not detected, test it with another computer if one is available. A persistent connection failure may require help from Apple Support or an authorized service provider.
