Apple Seeds First OS X 10.10.5 Beta to Public Beta Testers

os_x_yosemite_round_iconA few days after seeding OS X 10.10.5 to developers for testing, Apple has released the first OS X 10.10.5 beta to public beta testers. With only a few months until the public release of OS X 10.11 El Capitan, OS X 10.10.5 may be one of the last significant updates to Yosemite.

The new beta can be downloaded from the Software Update mechanism through the Mac App Store on Macs enrolled in the Apple Beta Software Program. The pre-release software's build number is 14F6a, the same as the OS X 10.10.5 beta seeded to developers earlier this week.

It also appears that the first OS X 10.10.5 beta is now showing up in Software Update for developers who were unable to see the pre-release software following its release on Tuesday.

OS X 10.10.5 beta includes stability, compatibility and security improvements.

OS X 10.10.4, the current version of OS X Yosemite, was publicly released on June 30 with multiple bug fixes and under-the-hood performance improvements, including the removal of the problematic Discoveryd process.

El Capitan is only in its infancy and riddled with Bugs whereas Yosemite fully matured with 10.10.4

I can never understand why people would prefer Beta software over established software

Yosemite is so yesterday.
Perhaps you would care to elaborate a little. OS X Yosemite 10.10.4 is rock solid stable whereas El Capitan is riddled with bugs.

Really? I have absolutely no issues with El Capitan, and it runs far smoother than Yosemite or even Mavericks ever did.

I think most people running it have a few minor issues (mainly with apps that have yet to be updated), but it is far from "riddled with bugs".

I wish I could say I don't care, because El Cap is around the corner, but the days of being able to throw the latest release on my devices without worrying are kind of over. I'd say at least since Mountain Lion it has become very advisable to wait for the *.1-release. I don't really care much about iOS, because the device is just not very crucial to my workflow, but with OS X it usually takes a while until everything is running as it's supposed to after a major release.
*.1 release??? Lately try *.3 or *.4 release before you get something stable
