Apple seeds OS X Mavericks developer preview 6

By , Aug 21, 2013

OS X Mavericks DP4 Setup

Apple has seeded the 6th developer preview of OS X Mavericks this afternoon. The download comes exactly two weeks after developer preview 5 dropped, which added both the Mac iBooks app and a new version of iPhoto beta.

The newest Mavericks preview comes alongside the final build of OS X 10.8.5, and is now available for download in either the Mac App Store, as a software update, or through Apple’s Mac Dev Center, to all registered developers…

Apple introduced Mavericks, its next generation desktop OS, at WWDC in June. It will be available to the public this fall, bringing along a number of new features including Maps and iBooks apps, Safari improvements, and much more.

We’re installing developer preview 6 on our machines now, and will be sure to update this post with any notable changes we come across. Stay tuned!

    IOS 7 Beta 7? C’mon Apple all us are impatiently waiting to see if you added any new features at the last minute ! For example : “quick reply”(wishful thinking)

    • Brandon Weidema

      if anything, we might see features pulled to prepare for the stable release of iOS 7 :/

      • Jacob Galea

        Perhaps so, the probably of that happening is still little

    • Damian W

      it took them months to make these betas fairly stable. Therefore, they are not adding new features. Stop dreaming.

      • Samir

        But hey it’s not impossible for them to add quick reply. They could have been working on it the whole time and just didn’t add it in to keep it as a surprise. Even for the devs. They’ve already added it on Mavericks so why not on iOS 7.

      • dpacemaker

        If anything this will be a new model feature, not available to the 5 or older.

      • Samir

        If they do add it, even to a new model. I’m sure it’ll be available for the 5. The five would be able to handle it. Now anything before the 5 don’t need to be considered, seeing that it can’t even handle iOS 7.

      • dpacemaker

        I agree, but Apple always seems to put a software exclusive in the new models.

      • Samir

        Except for iOS 7, every feature included is exclusive. And for them to include it in Mavericks and not iOS 7, is way beyond me.

      • dpacemaker

        True, you are right. I’ve been hoping for it with every Beta release. Maybe they are saving it for the event and it will be seen then. Possible they could be testing it in house only, since I wouldn’t think that it’s anything the Devs would need to deal with or use.

      • Samir

        Yea, I truly hope so. You and I both, just been waiting and waiting, once I’ve seen it on my Mac I was thinking that they have to add it on the iPhone, it’s much more need there than the Mac.

      • Damian W

        The mac quick reply is pretty useless. I rarely find myself using it because it is fast enough to launch the original small window for messages.

      • Samir

        Yea, thats why they should’ve added into iOS 7. I barely even use messages on my Mac. lol

      • Anthony Antunez

        If they were going to put in Quick Reply they would have shown it at WWDC, a huge feature like that wouldn’t just be put in last minute without having any beta testing or even being talked about before release.

      • Samir

        You have to read what I said, and also dpacemaker. We said they could’ve been working on it in house the whole time without releasing it to the debs for a surprise.

      • Anthony Antunez

        Highly doubtful. I have never heard of Apple doing this with a major feature for an OS as far as it didn’t involve a new device or hardware. But hey, I could be wrong. I would certainly like to have quick reply in iOS 7 but even if Apple was keeping it secret, devs still would have found some code about it in previous betas. For example the fingerprint code which has led to the fingerprint scanning home button rumors.

      • dpacemaker

        Yeah your right about finding the code, but it isn’t a feature that the Devs would need know about. Is it possible for them to have different iOS 7 builds in house with the feature and release a Beta to the Devs without it? I just think that’s in the realm of possibility. I am, and will be shocked that they would put Quick Reply into Mavericks, but not on their iPhones. I would assume that more iMessages are done on iOS devices than on Macs.

      • Anthony Antunez

        Well iOS and OS X are built by different teams so it isn’t unusual that OS X has something iOS doesn’t.

      • dpacemaker

        I get that but it seems to go against Apples fluidity of products. We will all find out when it’s released.

      • Matthew

        They are lead both by Federighi though.

    • Jacob Galea

      PLEASE!

  • Matthew

    Guys lets just hope that this means that the new iOS 7 beta is coming soon. They usually come at around the same time.

  • Question

    Lol WOWW!! i opened safari and saw “Apple Seeds” and i got hyper and than saw osx mavericks.. -_-

    • Jamie Tilden

      I actually got really excited for this. I’m loving using Mavericks on my new Mac and really hope this seed fixes the iMessages issue I seem to be having.

      • Jamie Tilden

        Yaay it did!

      • Samir

        What issue exactly?

      • Jamie Tilden

        I just couldn’t sign into iMessage on my MacBook Pro. I can now :)

      • Samir

        Oh my had worked fine lol

    • Jacob Galea

      Mavericks really doesn’t add much important stuff. I am looking forward to a redesign, hopefully next year.

  • Daniel Beecham

    Tomorrrow iOS7 BETA 7!!!

    • Jamie Tilden

      What makes you think this? Just because it would be a week after beta 6?

  • Netanel Ozan

    Somone chack that?

  • Phil Randle

    Fixes the stupid jumpy performance in Flash Video’s finally! Now Mavericks is perfect for me, its damn fast too.

  • Guest

    Let them catch the newest technologie before they add new features !! Wtf apple is convincing us that 330 ppi is better than the S4 with 1080 p and 440 ppi and a 5 inch screen. Samsung really did well this time and left apple far behind

    • Rudy

      I’m not an apple fan ( i own a HTC 1 and iphone 5 ) but i need to state some facts because it is clear that u don’t understand technology and ur falling for samsung marketing.

      Samsung claims a screen resolution of 441 ppi, and Apple gives the iPhone 5 a spec of 326 ppi.. This would be a clear cut thing – IF – pixels were the smallest dots on a screen – and – if Samsung used the same definition for a pixel as Apple – but they don’t. The smallest dot on a screen is a sub pixel – a combination of sub-pixels make up a pixel. The more sub-pixels you have the more pixels.

      How about counting the sub-pixels? Counting on the Galaxy S4 will get you 882 dots per inch.. Counting the same small pixels on the iPhone 5 will give you 978 sub-pixels.. By this count the iPhone 5 has 9% more sub-pixels per inch !

      So how come Samsung claims 441 ppi ? And Apple 326??

      Samsung counts 2 sub-pixels as one pixel. Apple counts 3 sub-pixels as one pixel. Blue OLED’s are the hardest to produce on screens.. Samsung – while very close on red and blues – has less then the iPhone. Samsung instead has even smaller green sub-pixels to help blend color. Basically Samsung has sacrificed some color-correctness- but IN REALITY no one will be able to tell.

      And even if Samsung has a TRUE 441 PPI the sad thing is for ANY COMPANY – and this includes future Apple products like the iPhone 6 ( which promises a bigger screen and more ppi ) that ANY PPi over 262 SIMPLY DOESNT MATTER..

      It’s called visual acuity. At 12 inches away – a person with 20/20 vision CAN’T see better then 262 pixels per inch. In fact 99% of 1080P High Definition Wide Screen Tv’s only have mid-200 ppi….( much less then what most get on about any modern smartphone screen )… If Apple or any company puts out a screen with 500 ppi next year it won’t appear any sharper then 300 ppi.. because your eyes simply don’t have the ability to clarify things that small..

      More or less ppi has become another marketing tool and although the technology gets better – ppi ( in itself ) beyond 300ppi ( on any size screen ) its useless unless you can install a bionic eye that make a person see better..

      • Damian W

        good study

      • mehrab

        I”d love to know which phone you prefer more and why the one or the five? Beyond that who do you think performs better?

  • Scroat

    Almost there. Then again this isn’t a public release. Which I don’t see the reason in complaints.

  • Matthew

    Umm final build of 10.8.5?

  • Pászli Balázs

    Anyone else notice airplay broke in developer preview 6?

    • Mario Adriano

      Yep… Mine is broken too! I think it would be a corrupted plist file…

    • Dan Zimmerli

      Yes, broke here, not good that they are breaking things this far in…

    • Chris Beck 

      Yeah, broken for me too. I had been really enjoying using my Apple TV as an extended desktop, but after installing preview 6, it the Apple TV just goes black and it doesn’t show up in the display list. Hoping they fix it in preview 7…

  • Sebastian Kaminski

    Huge Changes in Mavericks Beta 6 I’ve noticed immediately:

    – Mavericks – Seems like everything is so much smoother and faster.

    – Finder Window – Finally fixes the finder window bc every time i opened, tabbed, or clicked on another folder i would have to adjust the columns, not anymore.

    – Display Preferences – No need for QuickRes anymore, which you had to turn on with every restart and then have to adjust all the windows again. Now i turn on my rMBP and my screen is 1680×1050 without clicking anything and no need to adjust every window i open.

    – Safari – Its so much faster and no more glitches.

    Thats what I’ve noticed so far.

    • Timothy

      Would you consider this build to be ok for installation on a main computer? The main reason I haven’t upgraded to the DPs yet is because I only have one Mac, and it’s my main computer by far, and I didn’t want a non-reversible beta on it that was going to be slow and bug-prone.

      • Jamie Tilden

        First of all, it is reversible. I sold my old 2011 MacBook Pro which I was testing Mavericks on, but I downgraded to the current Mountain Lion for the buyer. On my Retina MacBook Pro, very recently purchased, I’ve got the this DP of Mavericks and I’m loving it more than any previous release of OS X!

      • Timothy

        Ah ok, didn’t know it was reversible. Thanks! Downloading it now.

      • Jamie Tilden

        If you’re downloading a copy of it, it will most likely be DP1 and when you install that, you’ll then have to go through the same process for every DP, via the App Store updates, all the way up to this DP6. I did that up to DP5 for my rMBP and it took quite some time. So just be aware that this is a bit of a process (at least an hour and a half), but I feel that it is totally worth to get to the current DP (iBooks is really nice and at this point most bugs have been satisfactorily fixed!).

      • Timothy

        Looks like I have my weekend cut out for me, lol.

  • Jamie Tilden

    I really love how iDB often says they’re updating and to stayed tuned. I’ve been tuned in for a while now and you guys haven’t said word one on if there are any changes or not. If there aren’t just say so. I can only report one observable difference that I’ve spotted: app icons in mission control appear to be smaller.

    • Alex

      When they say stay tuned, they mean to user comments on changes. eheh.

      • Jamie Tilden

        Even hours later, the article ends with “We’re installing developer preview 6 on our machines now, and will be sure to update this post with any notable changes we come across.”

        So at this point, they must have installed it, unless it took literally over 6 hours to install. Yet, they haven’t updated any changes, and, as I and a couple of others have posted, there have been a couple notable changes.

  • Canchume

    someone have the change log ?

  • Pászli Balázs

    is airplay working for any of you guys?

    • Andries

      Airplay is not working on my MBP Retina. sound is working but no picture.

  • rwidjaja

    with the latest beta, it breaks powerpoint and skype video. have to go back to older release of skype. and powerpoint is just busted. everything in powerpoint slide shows up as upside down.

    • rwidjaja
