What is the OS X Beta Program?

The OS X Beta Program lets you take part in shaping updates to OS X Yosemite by test-driving pre-release versions and letting us know what you think. Your comments will help us make OS X better for all Mac users. Sign up today, and the beta software will be available for you to install soon.

How can I participate?

To join the OS X Beta Program, just sign up using your Apple ID and install the latest OS X Yosemite beta Software Update. Then go ahead and start using it. When you come across an issue that needs addressing, report it directly to Apple with the built-in Feedback Assistant application.

What else do I need to know about using OS X Yosemite Beta?

We recommend installing pre-release versions of OS X Yosemite on a secondary Mac, since it may contain errors or inaccuracies. Please be sure to back up your Mac using Time Machine before you install the beta. This is beta software that is still in development, which means some applications and services may not work as expected.
