OS X Yosemite 10.10.5 Beta 1 Released for Testing

OS X Yosemite 10.10.5 beta 1

Apple has released the first beta build of OS X Yosemite 10.10.5 to Mac developers and Public Beta users. The beta build arrives as 14F6a and is compatible with any Mac that is able to run OS X Yosemite.

OS X 10.10.5 beta 1 is available to download now from the Mac Developer Center for registered developers to access the build, and the Software Update mechanism for Public Beta users. It’s unclear what is contained within OS X 10.10.5 beta, but typically a point release includes bug fixes, security improvements, and minor enhancements, and does not include any major new features.

Yosemite 10.10.5 beta 1 is part of the public beta program, but the small update to Yosemite is completely separate from the OS X El Capitan 10.11 public beta 1 release, which is accessible to any Mac user choosing to participate in the public beta program from Apple.

The latest stable build of OS X remains OS X Yosemite 10.10.4. Stable builds are recommended for the vast majority of users, as beta releases are often less reliable.

Separately, iOS 8.4.1 beta 1 was also released today for developers to test on iPhone, iPad, and iPod touch models.

    Is there any chance that the 10. 1o. 4 download can be downloaded without completely screwing up a 10.9.5 that is almost useable other than having some of these 06 look alike disadvantages left or added to . Or will the whole thing crash in an attempt by us rank amateurs! I really think I donated the wrong computer when I gave my son the mac with snow leopard!

    Does anyone know if the “update purgatory” problem is solved? I have three apps that update every day (imove,xcode, and Microsoft one drive).

    I suggest ignoring Itna’s advice. A Yosemite dot release beta should be much more stable than an El Capitan beta. The latter has some pretty significant issues at this point, including not being able to run Java applications.

  4. Rudy says:

    it is now available via the Public Beta program as well

  5. Raige says:

    The beta hasn’t become available in the updates – now a day later that released and enabled. MacBookPro11,3

    Not showing up for me on my iMac Retina 5K. No idea why. Might have to manually find and install the package.

      OS X 10.10.5 right now is an early beta, I would not bother installing it on anything. OS X 10.10.4 is the newest stable build.

      If you’re going to run a beta, run El Capitan, IMO. Yosemite is… well, we all know.

    What the point of this, If apple are going to release EL Capitan in few months they should be spending ALL their time get that right and not messing around with beta of what will soon be an obsolete OS

    • bagonias says:

      There are residual bugs in OS X Yosemite that still need to be addressed (I can think of a dozen or so) so Yosemite will still have some development effort. Given the state of OS X and iOS recently, the first releases of El Capitan will probably be fairly buggy too, so OS X 10.10.5 is more likely to be stable than OS X 10.11.
