Can the iPad Air and Older iPads Upgrade to iOS 12?

Yes, older iPad models like the original iPad Air can upgrade to iOS 12. In fact, iOS 12 serves as the final major operating system version supported by several vintage Apple tablets, including the first-generation iPad Air, iPad mini 2, and iPad mini 3. This guide outlines which older models are compatible with iOS 12, how to install the update, and the practical limitations of using this operating system today.

Supported Older iPad Models

Apple officially supported iOS 12 on a wide range of older hardware. The following legacy iPads are capable of running iOS 12:

  • iPad Air (1st generation): Can be updated to iOS 12, capping out at version 12.5.7. It cannot be updated to iOS 13 or later.
  • iPad mini 2 and iPad mini 3: Both models top out at iOS 12.5.7.
  • iPad Air 2: Can update to iOS 12, but also supports newer versions up to iPadOS 15.8.
  • iPad (5th generation and newer): Fully support iOS 12 as well as modern iPadOS versions.

Older models released before late 2013—such as the iPad 2, iPad 3, iPad 4, and the original iPad mini—cannot run iOS 12. Their software support ends at iOS 9.3.5/9.3.6 or iOS 10.3.3/10.3.4.

How to Upgrade an Older iPad to iOS 12

If your iPad Air or compatible device is running an older version like iOS 10 or 11, you can update it directly through the device settings or via a computer.

Updating Wirelessly (Over the Air):

  1. Connect the iPad to Wi-Fi and plug it into a charger.
  2. Open the Settings app.
  3. Tap General, then tap Software Update.
  4. If an update is available, tap Download and Install.

Updating via Computer:

  1. Connect the iPad to a Mac or Windows PC using a Lightning-to-USB cable.
  2. Open Finder (on macOS Catalina or later) or iTunes (on Windows or older macOS versions).
  3. Select your device from the sidebar or toolbar.
  4. Click Check for Update, then click Download and Update.

Limitations of iOS 12 Today

While iOS 12 significantly improved speed and stability on older devices like the A7-powered iPad Air, running it today comes with restrictions:

  • App Compatibility: Most modern apps in the App Store require at least iOS 14, 15, or 16. While you can often download the "last compatible version" of an app you previously purchased, many modern services (such as banking apps or streaming platforms) may no longer connect to their servers on iOS 12.
  • Web Browsing: The built-in Safari browser on iOS 12 does not support newer web standards, which can cause modern websites to render incorrectly or fail to load. Third-party browsers on iOS 12 use the same underlying Safari engine and face the same issue.
  • Security: Apple released iOS 12.5.7 in January 2023 to patch critical vulnerabilities. However, iOS 12 is no longer actively maintained with regular security updates, making it less secure for sensitive tasks than modern iPadOS versions.
