Sep 15, 2014 - 27 Comments

OS X Yosemite Apple has released OS X Yosemite Public Beta 3 to those Mac users registered with the public beta program. Additionally, Apple released OS X Yosemite Developer Preview 8 to Mac developers. The two builds include bug fixes and feature enhancements, and appear to largely be the same, pushing the release of OS X 10.10 ever closer to the public launch this fall.

Separately, OS X Yosemite Beta Recovery 1.0 is also available as an update, which is aimed at resolving issues with the recovery boot partition for Yosemite beta users.


Mac users who participate in the beta and development programs for OS X will find the relevant updates available to download from the Mac App Store, accessible from the  Apple menu.

      You can force the App Store to refresh Updates by hitting Command+R once you’re within the Updates tab, that should reveal the update to OS X Yosemite Public Beta and Developer Preview.

      There is some speculation this will be among the last Public Beta releases of Yosemite as we get closer to the GM build.

    Just started downloading it.

    Beta 3 would not install.Went to software update. Clicked on install beta 3. It seemed to download fine. It then restarted. Message says installing software update. Got to about 18 minutes and did not proceed from there for over an hour. Happens every time.

    If this is the last beta than the final release is going to be very buggy!

  7. Kevin Roa says:

    Each new beta is making my computer slower and slower. I think they are pushing me to buy a new computer.

    Just installed the PB3 and thought I would share some performance notes.

    Using 10.9.4, I have historically achieved a Geekbench 3 (64-Bit) score of around 2300 (Single Core) 4700 (Multi).

    Under the PB2 Yosemite release, this dropped to 1900 and 3700 respectively.

    Now under the PB3, the benchmarks are back up to where they were previously. In fact, the multi-core test is 4823, which is the highest I have ever tested on my 2010 15″ MBPro (i7, 8Gb RAM, NVIDIA GeForce GT 330M 512 MB).

    So far, looking good for me on Yosemite.

    Even though I haven’t had time to use it much, it seems that this release is less buggy, better, faster, closer to the Gold Master.

  10. Darren says:

    anyone having issues with mail client in Beta 3

  11. Radix says:

    I am trying to hit update button but it does not do anything… anyone having the same problem? How did you get by that?

  12. jv says:

    Still seems like handoff is not working…… bummer. It was working 2 versions ago.

    I am very pleased with my OSX Mountail Lion 10.9.4 version. However, I have trouble sending g-mail. My message goes into “Draft ” when I pause for even a few seconds. How do I avoid this problem ? Your OSX Daily is a excellent publication. Keep up the good work!

    Just installed this update on My MacBookPro 15″ late 2010 8gb ram and I ‘ve seen for the first 1 hour, fans running very fast and CPU users activity sign 75-80% with no App launched, no backups no indexing, nothing.

    So I lunched UtilityDisc App and repair permits, finish it and restart.
    At the restart, still crazy fans and CPU and User CPU activity up to 85-90%
    I switch off the MBPro 3-4 times, but at the restart fans at the max speed, no Apps and no external discs connected.

    Luckly, all return to the normality in this moment 2 hours after. So if Your Mac apparently goes craz, don’t worry :)

    • Yogi says:

      In my case it is the Calendar App which takes uses up all the resources and causes the fan to run faster and the CPU activity at 80-90%. This happens each time i restart. I have found the reason to be the calendar app, i force quit the calendar app. Immediately the mac starts behaving normally.

    Puttino, maybe Spotlight indexing? :D
