Problems using OverDrive on older Macs or web browsers

Users on older Mac computers (running lower than macOS 10.12.1) may have trouble using OverDrive's legacy desktop software and their library's OverDrive website in older web browsers. These issues are because of a change made by OverDrive's web certificate provider.

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

To continue using OverDrive:

• Mac users: OverDrive's legacy desktop software for Macs is 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 OverDrive for Mac.
  Note: If you update to macOS 10.15 or higher, you'll lose access to OverDrive for Mac.
• Browser users: Update your browser version.
