OS X Yosemite v10.10 beta 1 (14A299l)

OS X Yosemite v10.10 beta 1 (14A299l) | 4.98 GB

This fall, Apple will release OS X Yosemite, the latest version of its operating system for the Mac. OS X Yosemite features a brand-new look, tons of new features and tight integration with iOS 8.

A design area that OS X Yosemite really plays up is window transparency. The sidebars in apps such as the Finder and Messages are now semi-transparent. The effect lets you see more of what is happening in application ShiChuang in the background, especially while multitasking with lots of apps.

Known Issues
Safari may hang when playing certain Netflix content.
iPhoto 9.5.1 and Aperture 3.5.1 are required on OS X Yosemite. Update to these versions from the Mac App Store.
When entering edit mode in iPhoto, a black screen may be displayed instead of the selected photo.
Photo Stream and iCloud Photo Sharing may not function properly when both iPhoto and Aperture are installed.
The shared purchase history page on the Mac App Store is disabled for Family Sharing accounts.
