Mail OS X Yosemite

Apple seeded a new beta of its upcoming OS X Yosemite 10.10.3 update this morning. The software, labeled build 14D105g, is available through the Update tab in the Mac App Store for public testers, as well as the online Dev Center for all Mac developers.

The release comes less than a week after the previous OS X 10.10.3 beta, and it appears that it is nearly identically to its predecessor, save for a fix for a problem that prevented beta 3 from working with the 2015 Retina MacBook Pro and MacBook Air.

We’ve seen a number of new features thus far in the 10.10.3 betas, including support for Google 2-step verification when setting up accounts, Force Touch APIs for developers, various emoji improvements, and of course the all new Photos application.

As always, if you find something new we haven’t mentioned, e-mail us at

    Still trying to load my iPhoto Library over to Photos but it tells me it is not allowed to. Anyone have this issue? By the way, it doesn’t let me manually choose to import my iPhoto Library.

    Please help. Thanks!

      When i opened the Photos app for the first time, it automatically copied the iPhoto library to Photos.
      But the thing is now i have both iPhoto library and Photos library which is eating up my SSD.

        That didn’t even happen for me. Even if I try opening up iPhoto, select all 11,000+ photos/videos and then drag to the open Photos app still doesn’t let me. Very frustrating.

        I don’t know if it would help but try this once:
        Go to finder>pictures and then right click on iPhoto library and the go to open with, then select Photos app.

    Not sure what happened, what changed. But using iCloud Photo Library is no longer crashing the Photos App for me. This is pretty sweat. It is now a pretty seamless experience across the iPhone and Mac.

    Doesn’t force my MacBook into High performance GPU mode. Win in my book.

    Anyone having a problem with the ‘Optimize Mac Storage’?
    I have 10GB of Photos on my iCloud Storage and I have selected Optimize mac storage, even then its still taking 10GB of space on my mac.
