OS X 10.10 Yosemite available for developers today, customers getting it this fall

The beta for OS X Yosemite, announced today at WWDC 2014, will be available to developers today. Customers will get Yosemite this fall for free.

Those customers in the OS X Public Beta Program will be able to download and test OS X 10.10 before the consumer release as well, should they be brave enough.

Stay tuned to iMore and our liveblog of the Keynote for the latest news right from WWDC.
