How to Reset a Mac: Soft, Factory, NVRAM & SMC Guide

Introduction

When people search for how to reset a Mac, they’re often asking one of several very different questions. Some just need a quick restart to fix a frozen app. Others want to wipe everything and return the machine to factory settings before selling it. Still others need to reset specific low‑level hardware controllers—NVRAM or the SMC—to solve persistent glitches that a normal restart won’t touch.

Because “reset” means different things in different situations, this guide covers all of them. You’ll learn how to do a soft reset, a full factory reset, and the specialized NVRAM and SMC resets that Apple Support often recommends. Each method includes clear, step‑by‑step instructions for both Apple Silicon and Intel Macs.

If your problem is simply that your computer is sluggish or frozen and you just need to reboot, see our how to restart a Mac guide . If you’re planning to sell or give away your machine, our factory reset a Mac guide walks through the complete wipe process.

The Different Types of Mac Reset

A reset isn’t a single action. Depending on what’s wrong, you may need one of these four approaches:

Soft Reset: A standard restart that closes applications and clears memory. Fixes most minor issues.
Factory Reset: Erases all content and settings, returning the Mac to its out‑of‑the‑box state.
NVRAM/PRAM Reset: Clears stored settings like screen resolution, startup disk selection, and sound volume.
SMC Reset: Resets the System Management Controller, which handles power, battery, fans, and other hardware functions.

Each method serves a different purpose, and the steps vary between Apple Silicon and Intel Macs. Let’s walk through each one.

How to Do a Soft Reset (Normal Restart)

A soft reset is simply a restart, and it’s the first thing to try when your Mac misbehaves. It clears RAM, closes all applications, and reloads macOS.

Via the Apple menu: Click  → Restart.
Via keyboard shortcut: Press Control + Command + Power (or Eject on older Macs).
If frozen: Hold the Power button for 10 seconds, then press it again to power on.

This process does not delete any files or settings. For a complete guide to all restart methods, including Terminal commands and Safe Mode, see our how to restart a Mac guide .

How to Factory Reset a Mac

A factory reset erases everything on your Mac—files, apps, settings—and reinstalls a clean version of macOS. It’s the right choice when selling, trading in, or giving away your computer, or if you want to start completely fresh.

On Apple Silicon (M1/M2/M3/M4):

Open System Settings > General > Transfer or Reset.
Click Erase All Content and Settings.
Enter your admin password and confirm. The Mac restarts to a “hello” screen.

On Intel Macs with a T2 chip:

Restart and hold Command + R to enter Recovery Mode.
Open Disk Utility, select your startup disk (Macintosh HD), and click Erase.
Quit Disk Utility and choose Reinstall macOS.

How to Reset NVRAM/PRAM

NVRAM (non‑volatile random‑access memory) stores settings like screen resolution, startup disk selection, and speaker volume. Resetting it can fix display problems, boot issues, and strange audio behavior.

On Intel Macs:

Shut down your Mac completely.
Press the Power button, then immediately hold Command + Option + P + R.
Keep holding for about 20 seconds—your Mac may restart during this time.
Release when you hear the startup chime a second time (or when the Apple logo appears and disappears twice).

On Apple Silicon Macs: NVRAM resets are not needed. The system automatically checks and resets these values during startup. If you experience persistent issues, a standard restart is equivalent.

For a deeper explanation of when to use this and what it actually fixes, see our NVRAM reset guide .

How to Reset the SMC (System Management Controller)

The SMC controls power management, battery charging, fans, keyboard backlighting, and other hardware behaviors. Resetting it can resolve battery drain, fan noise, and power‑related issues.

On Apple Silicon Macs: There is no separate SMC reset. A normal restart or power‑off performs the equivalent function.

On Intel Macs with a T2 chip:

Shut down.
Press and hold Control + Option + Shift on the left side of the keyboard for 7 seconds.
While still holding those keys, also press and hold the Power button.
Hold all four keys for another 7 seconds, then release. Wait a moment, then power on.

On older Intel Macs without a T2 chip:

Shut down.
Press and hold Shift + Control + Option on the left side, plus the Power button, all at once.
Hold for 10 seconds, then release. Power on normally.

For model‑specific variations, see our SMC reset guide .

How to Reinstall macOS Without Losing Data

Sometimes the best way to reset a Mac is to reinstall the operating system itself—fixing system‑level problems without touching your personal files. This is called a “non‑destructive macOS reinstall.”

Restart and hold Command + R (Intel) or press and hold the Power button until “Loading startup options” appears (Apple Silicon).
Select Reinstall macOS from the Recovery menu.
Follow the on‑screen instructions. Your files and applications remain untouched.

A backup is always recommended before any system‑level operation. For a full walkthrough, see our reinstall macOS without losing data guide .

Resetting Without a Password

If you’re locked out of your Mac, you can still reset it using Apple’s built‑in recovery tools.

On Apple Silicon, shut down, hold the Power button until “Loading startup options” appears, then choose Options > Continue. From the Recovery menu, open Disk Utility to erase the drive, then reinstall macOS.
On Intel, restart and hold Command + R to enter Recovery Mode. Use Disk Utility to erase the startup disk, then reinstall macOS.

Be aware that this process permanently deletes all data on the Mac. Activation Lock may require your Apple ID password after reinstallation.

Frequently Asked Questions

Will resetting my Mac delete everything?
Only a factory reset or erasing your disk in Disk Utility deletes files. A soft reset, NVRAM reset, or SMC reset does not touch your data.

How long does a factory reset take?
Typically 30 minutes to an hour, depending on your internet speed and Mac model.

Can I reset my Mac without an Apple ID password?
Yes, using Recovery Mode and Disk Utility, but Activation Lock may require the password afterward.

What should I do before a factory reset?
Sign out of iCloud, back up your files with Time Machine, and deauthorize any licensed software.
