The OS X Yosemite beta program will be launched July 24, allowing users to test the system and give Apple feedback directly. Apple's Beta Program is limited to the first one million users who download the software with their Apple ID.
The new operating system comes with a new design and look, many new features and better integration and syncing with Apple's iOS 8 devices. Yosemite's new look largely borrows from iOS 7's redesign, which was done last year, and is expected to be more modern, with a brighter color palette and flatter designs.
Yosemite will also come with a refined toolbar, new notification-center features, and a dark mode.
Users can apply to the program on Apple's website and the company will send a redemption code that can be used to download OS X Yosemite from the Mac App Store.
Apple decided to make its new software available to the public ahead of its official release to increase loyalty and make sure users are accessing the new software. They did this first with the Mac OS X 10.9 Mavericks.
The new operating system was unveiled first during this year's Worldwide Developers Conference in San Francisco. Apple developers have had access to OS X Yosemite since the conference in order to give the company the required technical feedback and also help modify apps and programs to work with the new software.
