Similar to the recent OS X Yosemite 10.10.5 Beta, OS X Yosemite 10.10.5 Public Beta is also a minor update featuring bug fixes, as well as under-the-hood enhancements such as improvements in stability, compatibility, and security of your Mac. Although OS X 10.10.5 is expected to be the last significant update to Yosemite, as OS X El Capitan is only few months away from rolling out to the public.
You can get OS X Yosemite 10.10.5 Public Beta through the company's Beta Software Program for registered public beta testers.
