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 backup 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. If you are using iCloud Documents on Mavericks and you are also a member of the iOS Developer program, your documents will not sync across your other Macs and iOS devices.


What is the OS X Beta Program?

The OS X Beta Program allows users to try out pre-release versions of OS X. Help Make OS X even better by letting Apple know of any quality and usability issues you encounter. Please note that since pre-release software or beta software has not yet been commercially-released by Apple, it may contain errors or inaccuracies and may not function as well as commercially-released software. Be sure to back up your computer using Time Machine before installing this pre-release software and install it only on non-production or business critical machines.

Who can participate?

The OS X Beta Program is open to anyone with a valid Apple ID who accepts the OS X Beta Program Agreement during the sign-up process.

Do I have to pay a fee to join the program or pay for software?

No. Both the program and software are free.

What kind of compensation do I receive for testing?

This program is voluntary. There is no compensation for your participation.

What’s the difference between this program and the Mac Developer Program?

The OS X Beta Program is a program to collect feedback about pre-release software. The Mac Developer Program is a program for developers to test and build applications for OS X. There is no guarantee that participants in the OS X Beta Program will be given access to the same updates of OS X that the Mac Developer Program receives. If you are a developer writing an app for OS X, you will benefit from the additional resources available through the Mac Developer Program.

Is the pre-release software I am installing confidential?

Yes, the pre-release software is Apple confidential information. For example, don’t install the pre-release Apple software on any systems you don’t directly control or that you share with others, don’t blog, post screen shots, tweet or publicly post information about the pre-release Apple software, and don’t discuss the pre-release Apple software with or demonstrate it to others who are not in the OS X Beta Program. For clarity, if Apple has publicly disclosed technical information about the pre-release software then it is no longer considered confidential.

Support and Feedback

Will installing the pre-release software from the OS X Beta Program void my hardware warranty?

No, installing the beta software does not void your hardware warranty.

What if I have problems running the pre-release software?

Always back up your computer before installing pre-release software. If you need help returning your Mac to a shipping version of OS X and restoring from your Time Machine back up, you can call AppleCare to speak to a support specialist, or reference online documentation. If you wish to return to a shipping version of OS X, we recommended that you wait until the final version of OS X Yosemite is available. OS X Yosemite is coming this Fall, and it will be a free upgrade that you can install over your current installation. If you must remove the beta software from your computer, you will need to erase, install, and restore the Time Machine backup of Mavericks that you created before you installed the OS X Yosemite Beta. Any changes to your files and documents since you installed the OS X Yosemite Beta will not be preserved when restoring your Mavericks backup, so be sure to copy any new or changed files before you begin restoring from your Mavericks backup.

Speed up your Dashboard

Every widget creates a cache file. In theory, these cache files are meant to speed up Dashboard performance. But, the cache files can get bloated or corrupted, resulting in the exact opposite effect. If your Dashboard seems to be running unusually slow, you may want to try clearing those caches.

Go to:


You’ll find a cryptic set of folders with no names, just numbers. Delete everything inside the “DashboardClient” folder.

In order to complete the process, you need to restart the Dock (it controls Dashboard). You can do this in two ways:

Type in the Terminal:

killall Dock

This will quit and restart the Dock.
Open the Activity Monitor application (in your Utilities folder). Type “dock” in the search field. Once you find it, select it and hit the “Quit Process” button. The Dock will quit and restart.
That’s it. You’ve successfully cleared the cache files for your widgets. For me, this resulted in a significant performance boost. Dashboard is actually usable again.

Note: If you run several widgets, it will probably take several seconds for Dashboard to display the info in each widget the first time it’s activated after clearing the caches. Dashboard needs to rebuild the cache for each widget. Don’t be alarmed when they initially come up blank.

It should also be noted that the caches do NOT hold the actual data in the widgets. So, if you’re running widgets like, Mint, iClip lite, or Daily Grind Timer, the data will NOT be lost by clearing the cache.
