As of September 30, 2021, users on older Apple devices (Mac computers running lower than macOS 10.12.1 and iPhones/iPads running iOS 9) may have trouble using the OverDrive desktop or mobile apps. These issues are because of a recent change made by OverDrive's web certificate provider (learn more about their change).

This change may also affect those trying to use their library's OverDrive website in older web browsers.

Affected users may see security warnings or have trouble accessing some or all of the functionality of the OverDrive app or website, including signing in, browsing, borrowing, or loading content.

To continue using OverDrive:

  • Mac users: The OverDrive for Mac desktop app is now only supported on macOS 10.12.1 through 10.14. If possible, update your computer to one of these macOS versions to resolve issues with the OverDrive for Mac desktop app.
    Note: If you update to macOS 15 or higher, you'll lose access to OverDrive for Mac.
  • iPhone/iPad users: Update your device to iOS 10 (or higher).
  • Browser users: Update your browser version.

Update your iPhone, iPad, or iPod touch wirelessly

If a message says that an update is available, tap Install Now to update now. Or you can tap Later and choose Install Tonight or Remind Me Later. If you tap Install Tonight, just plug your device into power at night, and your device will update automatically overnight.

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. If you see two software update options available, choose the one that you want to install.
  4. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now.

You might see that your device is up to date on its current version, and there's an update available. For example, even if your device is up to date on the latest version of iOS 14, there might be an option to update to iOS 15.
