OS X Yosemite Beta Failing to Download for Some Users
Users in MacRumors forums, Apple support forums and on Reddit have complained about not being able to download OS X Yosemite from the Mac App Store. These users have successfully redeemed a promo code and initiated the installation, only to have it fail during the download process. This issue has persisted more than 24 hours after the beta was released, suggesting it is not a problem with server overload.
Can’t get OS X Yosemite to download properly. Maybe it’s the limit I can download per month or something. Gonna go to Starbucks and try it.— Micah (Trivol) (@TheMajesticW0lf) July 25, 2014
Apple's beta program has made OS X Yosemite available to up to a million new, non-developer users who now are experiencing the OS for the first time. Beta users can check out our first impressions post as well as our forums for troubleshooting tips, known issues and more.
