macOS Security Updates

Keeping your software up to date is one of the most important things you can do to maintain the security of your Mac.

Required and supported macOS versions

When security issues are discovered, Apple will release fixes only for recent versions of macOS. Older versions of macOS may remain unfixed, and thus vulnerable. UNC Asheville ITS supports only the versions of macOS that are actively receiving security updates.

How to upgrade to the latest macOS

Use Self Service to upgrade to the latest macOS. When you open Self-Service, you will see an option to Upgrade to macOS Ventura. Click Upgrade to start the process.

What do "supported" and "not supported" mean?

"Supported" means that UNC Asheville ITS will troubleshoot and resolve issues with a version of macOS.

"Not supported" means that ITS will not provide troubleshooting for a version of macOS. Instead, we will assist you with upgrading your Mac. Many issues can be resolved by upgrading to the latest macOS, so that is the first course of action to resolve any problems. Once your Mac is running a supported version of macOS, ITS will be able to assist with resolving issues.

If you receive an alert to upgrade your Mac

If your Mac is running an unsupported version of macOS, you may receive an alert prompting you to upgrade to the latest macOS.

The operating system on your Mac is out of date.

It no longer receives security updates from Apple, and is not supported by UNC Asheville ITS. You must upgrade macOS.
