Norton 360 is one of the most searched-for antivirus products in the United States,
and one of the most common questions we get before a purchase is simple: will it
run on my computer or phone? Norton still supports a wider range of Windows versions
than most competitors, but there are important exceptions, a few features that quietly
disappear on older systems, and separate rules for Mac, Android and iPhone. This
guide lays out the current Norton 360 system requirements for every platform, explains
what changes between Standard, Deluxe, Premium and Norton 360 for Gamers, and shows
you how to check your own device in under a minute.

Everything below is taken from Norton’s published device-security requirements page
as of November 2026. Norton revises that page when a new operating system ships,
so if you are reading this long after publication, use it as a reliable starting
point and confirm on Norton’s support site before a large multi-device purchase.

## Quick answer: Norton 360 minimum requirements in 2026

The device-security part of every Norton 360 plan (Standard, Deluxe, Premium, Deluxe
with LifeLock Select and Norton 360 for Gamers) shares the same baseline:

 * **Windows:** Windows 11 or Windows 10 (all editions except S mode), Windows 11
   on ARM processors, Windows 8 and 8.1, and Windows 7 (32-bit or 64-bit) with Service
   Pack 1 and SHA2 support.
 * **Mac:** Mac OS X 10.13 High Sierra or later, on Intel Core 2 Duo, Core i3/i5/
   i7, Xeon or Apple silicon (M1 through M4) Macs.
 * **Android:** Android 10 or later with the Google Play app installed. ColorOS 
   7.1 or later and ChromeOS 72 or later are also listed, again with Google Play.
 * **iPhone and iPad:** iOS 17 or later.
 * **Hardware:** a 1 GHz processor, 2 GB of RAM on Windows 11/10 (1 GB on 32-bit
   Windows 8/7, 2 GB on 64-bit), 2 GB of RAM on a Mac, 300 MB of free disk space
   on either, and 50 MB of free storage on Android.
 * **Browsers:** Google Chrome, Mozilla Firefox and Microsoft Edge on Windows; Safari,
   Firefox and Chrome on Mac.
 * **Internet connection:** required to download the installer, activate the key
   and run LiveUpdate.

If your devices clear those bars, any current Norton 360 key from our shop will 
install. The sections below cover the exceptions, which are where most support tickets
come from.

## Windows requirements in detail

### Windows 11 and Windows 10

Norton supports every edition of Windows 11 and Windows 10 except the locked-down
S mode, which only allows apps from the Microsoft Store. If your laptop came with
Windows in S mode you can switch out of it for free in Settings, Activation, and
Norton will then install normally. Windows 11 on ARM laptops (Snapdragon X Plus 
and Elite, and earlier ARM chips) is supported too, with one caveat: Norton Family
parental controls and Game Optimizer are not available on ARM devices.

Keep in mind that Microsoft ended free security updates for Windows 10 in October
2025. Norton still protects a Windows 10 PC, and that protection matters more on
an unpatched system, but if you are buying a multi-year license for a Windows 10
machine, factor in that the operating system itself is no longer being patched unless
it is enrolled in Extended Security Updates.

### Windows 8, 8.1 and 7

This is where Norton stands out. McAfee, Malwarebytes and most other consumer products
have dropped Windows 7 and 8 entirely, while Norton still lists Windows 8/8.1 (all
versions) and Windows 7 with Service Pack 1. There are two conditions. First, the
Windows 7 installation needs SHA2 code-signing support, which arrived through Windows
Update in 2019; a Windows 7 PC that has been offline since before then will need
those updates first. Second, some protection features do not work inside the Windows
8 Start-screen browsers, so use the desktop version of your browser on those machines.

If you have an older family PC that cannot move to Windows 10 or 11, a Norton 360
key is one of the few mainstream options that will still install on it. That is 
often the deciding factor for customers choosing between Norton and [McAfee, whose current requirements start at Windows 10 64-bit](https://infinitysolutions.digital/mcafee-system-requirements/).

### Processor, RAM and disk space

The published minimums are modest: a 1 GHz processor, 2 GB of RAM on Windows 10 
and 11, 1 GB on 32-bit Windows 7 or 8 and 2 GB on their 64-bit editions, plus 300
MB of free disk space. The Norton Bootable Recovery Tool needs at least 512 MB of
RAM. Those are minimums; 4 GB of RAM and an SSD make full scans noticeably faster.

## Mac requirements

Norton 360 for Mac requires Mac OS X 10.13 High Sierra or later, which covers Macs
going back to roughly 2010 as long as they received the High Sierra update. Both
Intel Macs (Core 2 Duo, Core i3, i5, i7 and Xeon) and Apple-silicon Macs from the
M1 through the M4 generation are supported. You need 2 GB of RAM and 300 MB of free
disk space, and an internet connection for LiveUpdate.

Three Norton features are Windows-only and are not available on a Mac at all: Norton
Family parental controls, Norton AntiSpam and Cloud Backup. If cloud backup is the
reason you are choosing Deluxe or Premium, make sure the device you want backed 
up is a Windows PC. Safari, Chrome and Firefox are all supported for the browser
protection components on macOS.

## Android, iPhone, iPad and Chromebook

Norton 360 for Android needs Android 10 or later and the Google Play app. That second
condition matters: phones and tablets without Google Play services cannot install
it, and Norton specifically lists Amazon Kindle and Fire devices and Huawei devices
as unsupported. Android’s multi-user mode is also unsupported, so install Norton
under the device’s primary user. The app needs about 50 MB of storage.

On Apple devices, Norton requires iOS 17 or later on iPhone and iPad. That rules
out the iPhone 8, iPhone 8 Plus and iPhone X, which stopped at iOS 16, but covers
the iPhone XR, XS and everything newer. Open Settings, General, About and read the
iOS Version line to confirm.

Chromebooks are covered through the Android app on ChromeOS 72 or later, again with
Google Play available. A Chromebook that has passed its Auto Update Expiration date
and is stuck on an old build may not be able to install it.

## Which Norton 360 plan fits your devices?

The system requirements are identical across the Norton 360 range; what changes 
is the device count and the extras:

 * [Norton 360 Standard, 1 year, 1 device](https://infinitysolutions.digital/product/norton-360-standard-1-year-1-device-usa-canada/)
   covers a single PC, Mac, phone or tablet and includes Secure VPN and a password
   manager.
 * [Norton 360 Deluxe, 1 year, 3 devices](https://infinitysolutions.digital/product/norton-360-deluxe-1-year-3-device-usa-canada-2/)
   and [Norton 360 Deluxe, 1 year, 5 devices](https://infinitysolutions.digital/product/norton-360-deluxe-1-year-5-device-usa-canada/)
   add more devices, more cloud backup (Windows only) and parental controls (Windows
   and Android).
 * [Norton 360 Premium, 1 year, 10 devices](https://infinitysolutions.digital/product/norton-360-premium-1-year-10-device-usa-canada-2/)
   is built for households with many devices.
 * [Norton 360 for Gamers, 1 year, 3 devices](https://infinitysolutions.digital/product/norton-360-for-gamers-1-year-3-devices-global/)
   adds Game Optimizer and notification silencing on Windows PCs (not on Windows
   ARM devices).

## How to check your own device in 60 seconds

### Windows

Press the Windows key, type _winver_ and press Enter to see your edition and version.
Then open Settings, System, About and read “System type” (32-bit, 64-bit or ARM-
based), “Installed RAM” and, under Storage, the free space on your C: drive.

### Mac

Apple menu, About This Mac. The first line shows the macOS name and version. 10.13
or higher is supported.

### Android

Settings, About phone, Android version. If it shows 9 or lower, check Settings, 
System, System update for an upgrade to Android 10 or later.

### iPhone or iPad

Settings, General, About, iOS Version. If it is 16 or lower and an update is offered
under Settings, General, Software Update, install it before activating Norton.

## Installation problems that look like license problems

Most “my Norton key does not work” emails we receive turn out to be environment 
issues rather than key issues:

 * **Installer refuses to start on Windows 7.** The PC is usually missing the 2019
   SHA2 update. Run Windows Update until no more updates are offered, then retry.
 * **Installer stalls or reports a conflict.** Another antivirus is still installed.
   Norton will not run alongside a second real-time scanner, so [remove the old antivirus completely](https://infinitysolutions.digital/remove-old-antivirus-completely/)
   with that vendor’s removal tool first.
 * **Protection shows as “at risk” after activation.** Restart the computer and 
   let LiveUpdate finish; the status normally clears within a few minutes.
 * **“System Extension Blocked” on a Mac.** Normal on macOS. Open System Settings,
   Privacy & Security, allow the Norton extension and grant Full Disk Access when
   prompted.
 * **Key reports as already used.** Norton keys are attached to the Norton account
   that first redeems them. When you move to a new computer, sign in to that same
   account instead of re-entering the key. Our step-by-step guide to [activating an antivirus license key](https://infinitysolutions.digital/how-to-activate-antivirus-license-key/)
   covers the Norton flow.
