How to Update to the Latest the Apple TV Operating System

Every update to tvOS, the operating system that powers the Apple TV, brings valuable new features with it. Because of that, it's generally a good idea to update to the new OS as soon as it's available. When OS updates are released, your Apple TV usually displays a message that prompts you to upgrade. 

The Apple TV 4K and 4th Generation Apple TV run software called tvOS, which is a version of the iOS (the operating system for the iPhone, iPod touch, and iPad) customized for use on a TV and with a remote control. Because of that, the process of updating the operating system will feel familiar to iOS users:

1. Launch the Settings app.
2. Select System.
3. Select Software Updates.
4. Select Update Software.
5. The Apple TV checks with Apple to see if there's a new version available. If so, it displays a message prompting you to upgrade.
6. Select Download and Install.
7. The size of the update and the speed of your Internet connection determine how long the process takes, but assume it will be at least a few minutes. When the installation is complete, your Apple TV restarts and is now running the latest OS.

Updating tvOS may be easy, but why bother going through all those steps every time? You can set the Apple TV 4K and 4th Gen. Apple TV to automatically update itself whenever a new version of tvOS is released so you never have to worry about it again. Here's how:

1. Follow the first 3 steps from the last tutorial
2. Select Automatically Update so that it toggles to On.

And that's it. From now on, all tvOS updates will happen in the background when you're not using the device.

The earlier models of the Apple TV run a different operating system (it's not tvOS), but they can still auto-update. While the 3rd and 2nd Gen. models look like they might run a version of the iOS, they don't. As a result, the process of updating them is a bit different:

1. Select the Settings app.
2. Select General.
3. Scroll down to Software Updates and select it.
4. The Software Updates screen offers two options: Update Software or Update Automatically.
   1. If you select Update Software, the OS upgrade process begins. Toggle Update Automatically to On or Off by clicking it.
   2. If you set it to On, new updates will be installed as soon as they're released.
5. If you selected Update Software, your Apple TV checks for the latest update and, if there is one available, displays an upgrade prompt.
6. Choose Download and Install. A progress bar for the download displays, along with the expected time to complete the installation.
7. When the download has finished and the installation is complete your Apple TV restarts. When it has booted up again, you'll be able to enjoy all the new features of the latest version of the Apple TV operating system.
