What is the OS X Beta Program?
OS X Yosemite will be available this fall. The OS X Beta Program lets you take part in shaping it 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. When the beta software is ready, you’ll receive a redemption code that will allow you to download and install OS X Yosemite Beta from the Mac App Store. 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?
Be sure that your Mac is running OS X Mavericks. If you don’t have OS X Mavericks, you can download it free from the Mac App Store. We recommend installing OS X Yosemite Beta 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. Since the beta software is unfinished, some new features will not be available, such as phone calls, SMS, Handoff, Instant Hotspot, and iCloud Drive. Spotlight suggestions are U.S.-based only. Some applications and services may not work properly with the beta software. When creating or making changes to documents stored in iCloud, your documents will sync only with Macs running the OS X Yosemite Beta and with iOS devices running iOS 8.
