OS X Yosemite (teaser 002)

In addition to seeding the fourth beta of iOS 8 this morning, Apple has also released the fourth Developer Preview of its new OS X Yosemite operating system. The update comes two weeks after Preview 3, and well over a month after Apple announced Yosemite at WWDC.

The update is labeled as build preview 4 1.0 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…

Also, Apple has released iTunes 12.0 and Yosemite Recovery Update 1.0 this morning. iTunes 12 features an ‘elegant new design’ and adds support for Family Sharing—a new feature Apple introduced at WWDC— improved playlists, a redesigned information window, and more.

We’re currently installing the Developer Preview 4 ourselves, and will be reporting back with any noteworthy 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.

    (May want to change the paragraph at the bottom from Developer Preview 3 to 4)

  • Liudas Bar

    U made a mistake “We’re currently installing the Developer Preview 3 ourselves”. It should be 4 😉

    • Tim Farris

      no its 4 i know for a fact because i used all my verizon data up downloading 3 when it came out if this is 3 i will be pissed off
      o you mean a typo well ya thats a typo lol

      • David Villamizar

        The screenshot says 4.

  • Tim Farris

    is there a way to install itunes 12 on windows?

    • Philippe Vézina


      • iDB

        ok, thanks 🙁

    • Not until fall, they don’t have a beta program for PC =

  • David Williams

    When can Windows users get the iTunes 12.0 beta?

    • justme

      I doubt it, maybe until final version. so looks pretty good the new UI for me.
      I hope iDB are working on it ( a new post dedicated only to a new iTunes 12) to see what are exactly the changes & new features on this version.

    • Probably some time in the near never. Windows has a different UI, and Apple probably want’s iTunes on a Mac to feel unique to the OS.

    • Tony

      It’s possible with the public beta of Yosemite coming up they may release a beta of iTunes for Windows but only time will tell.

    Start working at home with Google! It’s by-far the best job
    I’ve had. Last Wednesday I got a brand new BMW since getting a check
    for $6474 this – 4 weeks past. I began this 8-months ago and immediately
    was bringing home at least $77 per hour. I work through this link, go
    to tech tab for work detail

  • JAckson Cymerman

    I think it was a mistake not launching iTunes 12 w/ the first beta of Yosemite, just my opinion. I know it needed work probably, and still does but they could have at least used the new logo as previewed in WWDC.

  • Philippe Vézina

    Sidebar is definitely gone in iTunes 12, that’s a shame…

      • Tony

        Wow that’s horrible, that’s how I setup all my machines with iTunes installed. 🙁

      • CA

        I found a way where it feels like the sidebar is back. Waaaaaay better than nothing but I really hope they bring it back. I hate iTunes without a sidebar, it looks and feels so disorganized without it. But just check the picture I’m attaching and if you like it use the “Song List by Artist” sorting method and then click on “Playlists” and the sidebar pops up. 🙂

        edit: spelling

      • Tim Farris

        did you try looking for a terminal command or plist file edit to add it back if its just disabled you can reenable it or make one iTunes supports plugins and because apple is no longer doing it its not copyright just wait till the gm before you post it to avoid issues

  • catcher82611

    Anyone else not able to send text messages on the messages app on the new yosemite beta?

    • CA

      Just tried and it works, but it did take almost a full minute to send a message that just said “Test” to my iPhone. Maybe try logging out of iMessage and back in?

      • catcher82611

        It only seems to work one way. When I send an SMS from my phone, the conversation appears on my mac, however, when I hit enter on my mac, whatever I typed disappears

      • Alex

        im having the same problem on both the public beta and developer preview 4, i am going to try down grade to DP3 to try get the function back because i love it while pretending to do school work! (macbook pro 13inch mid 2012 model)

    • Chris

      Mine is only receiving text messages (non iMessages) and does not send.

    • You ever get that fixed? I am experiencing the same issue.

      • catcher82611

        I honestly wound up downgrading back to mavericks, it wasn’t worth the hassle to me

  • Robin Keanu Keim

    In DP4, the calculator has a new UI that looks like the iPhones calculator and finally matches its App Icon, Changing the System from Light to Dark Mode is now done by a check box in System Preferences (used to be a Popup Menu)… Thats all I found for now…

  • Tim Farris

    you do know if you got mac 10.9 you can get the dev preview without paying they don’t check uuid’s thats how i got it here is a link to the site to download it without a dev account or waiting on the beta program note the url at the top i didn’t wanna wait to post the url so the pic will b here in a min as it takes a min to upload to the site lol

  • Chris

    Do you have Bluetooth enabled on both your iDevice and your Macbook?

    Also you need to ensure you have Bluetooth 4 otherwise it won’t work based on earlier reports.

    • Edgar Gonzalez

      Bluetooth enabled on both sides, yes I have Bluetooth 4.0 🙁

      • Chris

        Quoted from Lifehacker

        Go to the Apple Menu, choose About this Mac, then click More Info, and then click on the System Report Head to the Apple Menu, then go About This Mac > More Info > System Report > Bluetooth. Look at the LMP Version. The version needs to be 0x6 for Handoff to work.

      • Edgar Gonzalez

        Oh God XD i think that my mac is trying to troll me

  • DP4 giving me serious Wifi issues and hate the no sidebar in iTunes

    • I am having Wi-Fi issues too.

      The new iTunes is cool. 🙂

  • hi what is the whole verbose mode look like does anyone have the whole boot process in verbose mode sorted out in images?

  • 3l Principe

    Skype not working for me. Anyone else made it work?

  • Joe Brunet

    You might wanna change the hardware inside your mac, Don’t need to purchase a complete new mac but a simple and inexpensive card will do the trick
