OS X Yosemite (teaser 002)

In addition to seeding the third beta of iOS 8 this morning, Apple has also released the third Developer Preview of its new OS X Yosemite operating system. The update comes three weeks after Preview 2, and over a month after Apple announced Yosemite at WWDC.

The update is labeled as build 14A283o and can be downloaded via an update in the Mac App Store, or as a full download from Apple’s online developer center. It does not, however, appear to be out in Apple’s recently-launched public Yosemite Beta Seed program yet…

The previous beta brought about just a handful of changes including a new Screen Sharing option to block others, a revamped Tim Machine interface and more. It also re-added the Photo Booth app with an all-new icon and enhancements for Handoff and AirDrop features.

We’re currently installing the Developer Preview 3 ourselves, and will be reporting back with any notable changes, so make sure you keep checking back with us throughout the day. If you find something not mentioned here, feel free to e-mail us at tips@idownloadblog.com.

  • New QuickTime icon

  • Omar Abbasi

    Dark mode is out!

  • I love the new QuickTime icon. But still, hate the Settings icon. :/

    who cares we want whats new in iOS 8 beta 3!!

    • Don Alberto Garcia Isais

      No

    • William Melendez

      There’s another post for iOS 8 = ) so get out of here , jk. Yes I want to know what’s new on iOS 8 and Yosemite beta 3!

    • Jonathan

      Turn the “we” into an “I”, cause the rest of us want to know what’s new in Yosemite too.

    • Well then, how about to go to the iOS 8 beta 3 page, instead?

  • Adham

    Phone Calling now works.

    • Ekitchi

      Did you tried this with an iOS 8 device? Thanks for the info, in both cases. 😉

      • Atmospheric Music

        It is only possible with an iOS 8 device and yes it actually works now but Face Time that makes it happen does not work, it freezes and glitches out a lot.

      • Ekitchi

        Thanks for the answer, mate. I guess I’ll have to wait the iphone 6 to enjoy this. My old iphone 4 is getting too old, I guess.

      • Adham

        Yes, has to be an iOS 8 device. And As Atmospheric Music has stated, it is still very buggy. I touched my phone while I was on a call and the call disconnected without warning lol. Oh well, first beta it’s working, there is bound to be bugs.

  • CA

    Still no themed iTunes or iTunes icons for me. Same for everyone else? Dark mode looks really nice though! 🙂

    • Hunter

      Same here

    • ✯Mike✯

      Very disappointed in iTunes not being included

    • Chris

      Apple most likely won’t release the iTunes update until either just before or after iOS8 is released

      • JAckson Cymerman

        It’s in the latest update Yosemite DP 4.

      • Chris

        That’s not a release version, until the iTunes update is publicly available it’s considered as an unreleased app update.

  • JAckson Cymerman

    Calling people now works on mac 🙂

    • Alex Marwaha

      how do i call???

      • Ilya Kos

        You need an iPhone running iOS 8 with Bluetooth LE 4.0 on both the mac and the iPhone

      • Arin Failing

        Not quite…. all you need is to be on the same WiFi as your Mac, and be running iOS8 beta3 / OSX10.10 dp3. Fortunately for those of us with older Macs (mine is mid 2010 iMac 21″), this feature DOES NOT require BT LE.

      • Nick Viveiros

        Hopefully there can be a hack to enable Handoff and AirDrop iOS to OS X on older computers. Can’t afford a new machine right now!

      • Julian Gigola

        there can’t be any, sorry man. Apple is all about performance and reliability.

    • aliyousef

      I used dialogue last version with Yosemite with bluetooth- It is Perfect without apps for iphone like connect

      Wonderful apps with mac

  • XanMania

    Has anyone tried handoff on a not compatible mac with a bluetooth 4.0 dongle? Does it work then?

    • It doesn’t work with dongles. Sorry.

      • XanMania

        Well… that sucks… So I have to upgrade my 2010 MBP at the next update. OSX 10.11, I guess

    • aliyousef

      dialogue is greet apps

  • Ilya Kos

    Does anyone know when the public beta is coming out?

    • XanMania

      I think it will be the RC or one version before the RC.

      • Ilya Kos

        Any approximate date?

      • XanMania

        Yosemite will drop at september I think. So at the end of july or begin of august. 🙂

  • ✪ aidan harris ✪

    I don’t see it listed in software update and the redeem link says I’ve already redeemed it (because I have). Anyone else having issues updating? My current version of Yosemite is OS X 10.10 (14A238x)

    • XanMania

      Turn your network off, restart, turn it on again and restart again. Solved it for me.

    • ✦ intelligent anomaly ✦

      Should be available via software update (is for me) – good luck!

  • Mr.DnQ

    the third beta is not in my mac appstore…
    I’m still on beta 1…
    Scared to download the full version because last time my mac kept rebooting

    • Hussain Alsanona

      Are you a registered developer?

      • Mr.DnQ

        yes I am

      • CA

        try rebooting, logging out of App Store , etc..

    • joseph gimenez

      I ended up needing to create a new user within mac os and then logging into that user and accessing the app store from this new account. The developer update showed up for me at that point.

  • Tony

    Installing this tonight for sure!

    • Hussain Alsanona

      nope

      • Tony

        Ah well, thanks! 🙂

  • Ilya Kos

    Xcode 6 beta 3 is out

  • Jake Rogers

    Not really relevant, but should I upgrade from iOS 7.1 Beta 3 to 7.1.2 and jailbreak? I heard pangu used an enterprise certificate glitch that requires you to change the time and stuff. I an wondering if I should wait for an iOS 8 jailbreak but evasi0n or if it is safe enough to use pangu. I am not worried about a trojan or anything, just that apple can fix something server side and screw me up or that I will have any future issues stemming from the date thing. Help?

    • XanMania

      Why do you ask this under a post about !!!!OSX!!!! Yosemite???

      • Jake Rogers

        I wanted to post where there was traffic.

    • Chris Gilmore

      Yes upgrade

    • Ethan Humphrey

      Why are you still on 7.1 beta?!?!?! It could expire any day now, and I’m not sure if it has already. So yes, upgrade.

  • Owen Reece Howarth

    When did the public preview become available?! I put my email down and was shown a “We will email you a link or whatever when available” but i havent received yet.. Does this mean i wasnt within the 1 million limited people?!

    • ✯Mike✯

      You have to be a registered developer to receive the betas.. the beta program is not live yet.

    • HDERAZI96

      Nope maybe your are. the public beta still not released you should wait what we are using DP (Developer Preview)

  • neil belanger

    can i update from beta 2 to 3 in the app store even tho im not a dev ?

    • Deniz Batun

      yes you can

      • neil belanger

        thx

  • Jorge Castro

    did you notice dark mode is out?

  • Brady Bluhm

    Adobe After Effects is working!!!

  • Alex Marwaha

    guys how do i call people using my mac on this new dev preview??

    • HDERAZI96

      Make sure connected w you iPhone via Bluetooth if you are and you cant may your device not supported or the shut the service for now

  • Guest

    I like the new dark theme, goes well with my wallpaper 🙂

  • HDERAZI96

    is it still buggy or more better

    • ✦ intelligent anomaly ✦

      Safari still has a ways to go, but overall the OS is stable (has been since the second preview). For now I am forced to use Chrome until Safari gets its round of bug fixes.

      • HDERAZI96

        Upon what you said i decide to install it but in seprate HD already know how to downgrade without losing file but i need final cut if it work i will install it as main

      • ✦ intelligent anomaly ✦

        When I first installed Yosemite, I was very skeptical, and kept my Mavericks just in case. After a while though, it has proven to be very reliable (OS-wise) and although there are some quirks with Safari, they are minor. I’ve since wiped my Mavericks and are now 100% Yosemite, and this is a development box too, which gets pushed to it’s limits quite often.

  • ✦ intelligent anomaly ✦

    Overall, DP3 seems to be running quite well on my Hack Pro. Quite stable, faster (over DP2), and overall impressive. Safari still has it’s problems but that will be ironed out eventually.

    • HDERAZI96

      What do you mean w hack pro (Mac pro ) ?

      • ✦ intelligent anomaly ✦

        I use a custom PC, not a Mac.

      • HDERAZI96

        Hackitosh or something like that right ?

      • ✦ intelligent anomaly ✦

        Yes, exactly

      • HDERAZI96

        😉

  • Sachmach29

    Interesting. Messages makes your conversations have the person’s first name and last initial now. If I was messaging Tim Cook, the conversation view would now say Tim C.

  • Christian

    Time Machine*****^

  • holmanvids

    Mine won’t update beyond the initial seed!!!!!!!!!! Any idea how to fix it?

  • Josef

    Dark Mode great, but I hope they will make it automatic later – e.g. for evenings and if ambient light is low…
