macOS 10.15 Support Ends June 30, 2025: Take Action Now

Posted: January 30, 2025

As of June 30, 2025, devices running macOS 10.15 (Catalina) will no longer be able to log into university systems due to security risks and compatibility issues. This version is now many releases behind the current macOS and poses significant vulnerabilities.

What This Means for You

University-Owned Devices:
All university-owned machines have been updated automatically where possible. If your device is too old to support a newer macOS, it must be replaced.
Personal Devices:
Personal devices used to access university systems must be updated or replaced to a supported macOS version.

How to Prepare

Check Your Current macOS Version
- Click the Apple menu > "About This Mac" to see your version.
Upgrade Your Operating System
- Follow Apple’s steps to update macOS if your device supports newer versions.
Replace Outdated Devices
- If your device cannot upgrade beyond macOS 10.15, please plan to replace it before June 30, 2025.

Why This Is Necessary

macOS 10.15 is no longer supported by Apple, leaving it vulnerable to cyberattacks.
Staying updated protects your data and ensures compatibility with university systems.
