Is your Mac up to date with the latest version of the Mac operating system (macOS or OS X)? Is it using the version required by some other product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.

Update to iOS 14 or iPadOS 14. IOS 14 and iPadOS 14 make your iPhone, iPad, and iPod touch even more intelligent, more personal, and more private.

If your macOS isn't up to date, you may be able to update to a later version.

Which macOS version is installed?

From the Apple menu  in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Mojave, followed by its version number. If you need to know the build number as well, click the version number to see it.

This example shows macOS Catalina version 10.15 build 19A583.

Which macOS version is the latest?

These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Catalina. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.

If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.

You can update your iPhone, iPad, or iPod touch to the latest version of iOS or iPadOS wirelessly.* If you can't see the update on your device, you can update manually using your computer.

Before you update

Make a backup of your device using iCloud or your computer.

Update your device wirelessly

If a message says that an update is available, tap Install Now. You can also follow these steps:

1. Plug your device into power and connect to the Internet with Wi-Fi.
2. Go to Settings > General, then tap Software Update.
   
3. Tap Download and Install. If a message asks to temporarily remove apps because the software needs more space for the update, tap Continue or Cancel. Later, iOS or iPadOS will reinstall apps that it removed. If you tap Cancel, learn what to do next.
4. To update now, tap Install. Or you can tap Later and choose Install Tonight or Remind Me Later. If you tap Install Tonight, just plug your device into power before you go to sleep. Your device will update automatically overnight.
5. If asked, enter your passcode. If you don't know your passcode, learn what to do.

If you see an error or need more space when updating wirelessly

If you see an error message while trying to update your device wirelessly, learn what to do. If you need more space for a wireless update, you can update using your computer or delete content manually from your device. Whether you use your computer or update wirelessly, you'll have the same amount of free space on your device after you update.

Some software updates aren't available wirelessly. VPN or proxy connections might prevent your device from contacting the update servers.

Customize Automatic Updates

With iOS 12 or later, or iPadOS, you can have your device update automatically overnight while it's charging. To turn on automatic updates, go to Settings > General > Software Update > Customize Automatic Updates, then turn on Install iOS Updates. Your device will automatically update to the latest version of iOS or iPadOS. Some updates might need to be installed manually.

With iOS 13.6, or iPadOS, you can choose not to download software updates automatically. Go to Settings > General > Software Update > Customize Automatic Updates, then turn off Download iOS updates.

Update your device using your computer

If you can’t update wirelessly on your device, you can update manually using a computer that you trust. If your computer is using Personal Hotspot on the device that you’re updating, connect your computer to a different Wi-Fi or Ethernet network before you update.

1. On a Mac with macOS Catalina 10.15, open Finder. On a Mac with macOS Mojave 10.14 or earlier, or on a PC, open iTunes.
2. Connect your device to your computer.
3. Locate your device on your computer.
