OS X 10.8 Mountain Lion Release Date: Summer 2012

Mac OS X 10.8 Release Date

Update 6/11/2012: OS X Mountain Lion will be available in July for $19.99!

OS X 10.8 Mountain Lion is currently available as a Developer Preview, meaning registered Mac Developers can access and download the next Mac OS right now. But what about the rest of us? When can we expect to have OS X Mountain Lion on our Macs?

The public release date of Mac OS X 10.8 Mountain Lion is slated for “Summer 2012” , this is posted both on Apple’s Mountain Lion preview site and was mentioned by Apple’s marketing chief Phil Schiller.

A summer 2012 release is just a year after the release of OS X 10.7 Lion, indicating that Apple is cranking out new OS versions faster than ever before. In fact, Mac OS X is now expected to have a major update every year from now on, a break from Apple’s previous tradition of releasing major updates every other year.

How will you get OS X Mountain Lion? The same way as OS X Lion became available, it will be an upgrade offered directly from the Mac App Store as a simple download and install. Prices aren’t yet known, but it’s largely expected to be another $29.99 update, matching OS X Lion’s price.

Stay tuned, we’ll update you as we learn more specifics.

    I still remember using OS X 10.8 when it came out, although it had few problems, it was gradually improved with updates.

  2. Mike says:

    Not happy with snow leopard update when loaded on my Macpro I couldn’t access my Microsoft products and it told me I had to update to new micro soft products software. Hope the lion doesn’t do the same ,also snow leopard slowed my Mac. In frustration went back to my original software.

    Is it worth it to even wait for the OSX? Or should I just buy the current?

  6. CH says:

    Hey all. New here so go easy.

    So Apple are sending out all the reminders to switch to iCloud, or lose all .mac emails. 30 days left to do so…. ML supposed to come out Summer 2012…

    Do I wait it out for ML or do I upgrade to Lion in the meantime? Still keeping a separate drive for SL!

  7. JP says:

    Hey dudes… I started my Apple experience few back in 2008, I brought the white MacBook with Leo installed.

    Later SnowLeo was released and I brought it – it was simply the best OS I have tried. Later I brought the an iMac, MacBook Pro and latest a Mac Pro. Meanwhile Lion was released, but shame shame shame… I didn’t like the Lion… it was full of failures, and it seems that Apple didn’t want to fix it in their updates even today….

    So I will like to say, that SnowLeo is one of the best OS Apple ever will be and has been made. This is solid facts!!!

  8. Apple Fan and Cynic says:

    You guys are missing the point. Apple’s clear strategy is to incrementally move away from the desktop altogether. Their iPhone/iPad product line is much more profitable and allows them to completely control the user experience (not to mention collect revenue directly from the user at every turn). Every iteration of OS X is going to look and work less and less like a desktop machine (e.g., local storage, user-controlled configuration and management of data) and more and more like an iPad (e.g,. cloud storage). Speaking as an old Unix geek from way on back I hate it, but it’s the way they are moving.

  11. Mel says:

    If mac plans to release a new OS every year and if it is not compatible with older apple products than for sure they will lose my business. Apple will be pushing away long term customers. I am a heavily apple user: Macbook, Ipod, Ipad, Iphone, Apple TV… plus their softwares, if I cannot keep up to date what is the point of me spending top dollars on hardware? I might as well buy something cheap that I know will just have to replace in 4 years or I can easily maintain and replace the hardware, aka PCs.

    Ok its a stupid question but i m a bit new to mac
    I was about to buy macbook pro but waiting for a month if therz a reasonable upgrade in hardware so
    The question is if any time i buy apple laptop will i revice free OS Updates?? Like i update my windows7 when ever its update available…
    Or i have to pay for updates?? If so then how much they charge normally??

    • Caleb says:

      Normally, you don’t have to pay for updates, unless they are updating to a new OS, as with any windows computer (ie Vista to 7). If you can, I’d hold off on buying that new computer until the new OS is released, because it won’t be running the latest. There are many quite regular updates that you absolutely do not have to pay for.

      Hope this helps.

  15. […] Apple has released OS X Mountain Lion Developer Preview 3 to those registered with the Mac Developer program.

  16. Hakintosh says:

    I’ve been intergrading osx on to my PC to see what all the fuss was about with Mac Os and to try it out before purchasing a real Mac. And after all these updates SL–>L–>>MtL. Seem I’ll be quite happy staying with Microsoft…! Mac no viruses >>>Yher right…!

    • Trav says:

      You were still running OS software while you were running Microsoft software, the virus could have come in from there. Mac’s are immune to PC viruses, but that doesn’t mean people aren’t developing OS viruses. I’d take Apple over Microsoft any day! Plus Microsoft updates haven’t really been “all that” either; need I remind everyone of Windows Vista? In my opinion Mac’s work much better than PC’s, and I can deal with out the “Save As” button, common guys.

  17. Will Mountain Lion include the iCloud software? I do not have Lion.

    I don’t like it so far, namly the new screen savers, they look horrid and the classic one which had nothing wrong with it had nice smooth transitions, it has gone to the dumps! It has limited photos the transitions are not fluid at all and it moves way to fast. pictures look grainy it ***** it does not even go full screen and ken burns effect looks like a kid made a slide show no class at all it is that bad!!!!!!!!!

    Also in safari the google search is gone it is intergrated into the address bar, the reason I don’t like it is before you could change your search engine from the browser and also see your past searches pretty handy, now you cant???????? plus all this twitter **** gona raise security isues I would think…… anyway that is my oppinion and I have used osx since 10.0.1

    VERY POOR fix the screen saver back to the way it was I know it is a small thing but small things say alot!!!!

    One good thing I noticed The tracking on my magic mouse seems better!!!!!!

  23. Eric says:

    So I haven’t update my MBPro to Lion yet due to some older apps I’m slowly weaning away from. It’s feeling like I should just wait for Mtn Lion at this point. I still have Mobile ME until June and, hopefully, Mt. Lion won’t be too much after that.


  24. […] have Notification Center support tied in, although this will certainly change as we approach the Summer release date. Also, it’s worth keeping in mind that chances are reasonably high that Growl itself will end […]

  25. Vinayak Kanagi says:

    I am excited about this new OS X Mountain Lion, and i’ll be definitely purchasing it. They are revolutionizing the OS X, making it more like an IPhone and an IPad.

    • John says:

      Turning a desktop OS into something that fits a tablet is revolutionary?

      • Max says:

        While I know what your saying, technically a revolution doesn’t have to be an improvement. In fact the latin word it comes from means to turn around. :o

  26. Santos says:

    does anybody know if the developer edition deletes everything and makes it a brand new os or keeps your old files like lion when it first came out

  27. revbj says:

    My MacBook was given to me Christmas 2007 – it runs Lion but according to the notes on OXDiary it won’t run Mountain Lion. This is a bit naughty – it seems to make my mac obsolete. Will there be anything I can do to upgrade my Macbook to help it fit the requirements. Or do I just soldier on as lame duck

    best wishes to all

      Beginning Rant mode…

      No you CAN”T just solider on with Snow leopard if Apple blocks you from running ML on your Macbook.

      As soon as ML comes out you won’t be getting security updates for SL. Have fun having your mac be a zombie when the latest version of the flashback trojan comes out. Ask 10.5.8 users how they feel about that? In 2012 you simply cannot go on the internet with a machine that does not receive security updates unless you want to totally screw yourself. Upgrade to Lion you say? Apparently that will only help for 1 year. After that only ML and its replacement will supported.

      The apple ecosystem only plays nice with the newest products. As it is on SL your sol when it comes to iCloud and software development.

      3) Scr*w Apple for putting us on a update a year schedule where older products fall by the wayside even faster. I own a late 2007 Macbook and a 1st gen Mac mini let alone a ton of ipods. I certainly am not feeling the love I used about my expensive computers now that one of them is obsolete and the other one will be soon, even though they are perfectly usable for a while to go. Its amazing what an SSD will do to an computer.

      Say what you want about MS but at least with Windows 7 you can get a nice OS that will be supported for many years to come and runs on any old computer, unlike how Apple handles security updates. To be honest I don’t even care about iCloud or what ML offers but I do care that SL is very soon about to be orphaned and unusable because Apple refuses to supply security updates which they can EASILY afford to pay developers to do. End of Rant…

    • phil says:

      brian you can update to Snow Leopard

    • NormM says:

      From what I can see, the Macbook3,1 (late 2007) should be able to run both Lion and Mountain Lion. I’m not sure why mb started ranting about Snow Leopard, when that wasn’t what you asked about.

    • William says:

      I’m pretty sure there’ll be a way around it. I remember when Lion was first released you couldn’t install it on a Duo Core but that’s possible by just removing a file from within the disk image so I assume that the same work around will apply.

  28. Dreamcat says:

    Is it advisable to wait and just upgrade from Snow Leopard to Mountain Lion?

    • Paul says:

      It’s not known yet if users will be able to jump from Snow Leopard to Mountain Lion, when we know we will let everyone know. If you are happy with Snow Leopard for now though, there’s no hurry to upgrade.

  29. Anonymous 10.8 says:

    I am currently running 10.8, and it’s not that much different. They added a lot of hidden extra stuff to it, like there being a google option in safari. The Desktop & Screensaver option is kind of fun, because it adds a bunch more options. They also added a Growl-type notification system. I would like it more if i needed it. All of my apps (Adobe Master Collection and others) work, but since it’s a beta, most of the new preferences “accidentally” force quit System Preferences. Oh, and they reset my custom dock. NEH!

  30. Dan says:

    Too quick. There are plenty of places that are still on SL, waiting for compatibility fixes for 3rd party and workflow software before they move to Lion. Now Apple move the goalposts again? They’re risking further fragmentation of the installed base, which will make it much harder to support Macs, driving more businesses away.
    iOS has been great at promoting OSX to business, but they need to give IT depts time to test fully before deployment. 10.7 has only just gone stable, although there are still reports of Wi-fi Issues. Moving to 10.8 is a step that will demand even more work.

    • Craig says:

      Skip lion, and wait for Mountain Lion. If you have an iPhone, iPad, or apple tv Mountain Lion will integrate your computer and devices. SL 10.6.8 its stable and still allows applications with powerpc architecture. There is a bunch of applications that will no longer work in Lion or Mountain Lion, due to Dual architecture.

  31. KKDK says:

    There is noting much improved apart from integrating stuff around, I would definitely say Apple has to give it as free update to all OSX Lion users. There is not lot improved from performance/footprint of OS apart from improving Integration of iOS with MacOSX. There are lot of improvements from Leopard to SnowLeopard, but not much from Lion to Mountain Lion, so my vote is no no to $$ update unless its free.

    • Phillip says:

      Have you ever owned another operating system? Microsoft charges HUNDREDS for their operating systems. I’m glad $30 will break the bank. Write your own operating system.

  32. Ian says:

    Does this mean we may see the return of “save as” ?

  33. Sheryl says:

    Not sure that I’m thrilled about this. It seems like Apple still needs to work out some of the issues with Lion, and a new OS is rolling out already?

    • Paul says:

      I can understand the hesitation, but from what I am hearing from those running Mountain Lion already there are many features and issues with Lion that have been fixed in the Dev Preview of OS X 10.8 already. So don’t be discouraged, this should be an exciting update that brings more features and greater stability. There was a huge difference in performance and stability between OS X 10.5 Leopard and 10.6 Snow Leopard, the jump from 10.7 to 10.8 could be much the same.

      • Sina says:

        I’m not sure I agree about 10.5 to 10.6 being a huge difference in performance. When I upgraded from Tiger to Snow Leopard on my iBook and iMac (I did a clean install), the computers slowed down tremendously. I got SO fed up after 6 months that I bought a copy of 10.5 Leopard (I finally found a new copy at an Apple Store), and everything was perfect. Snow Leopard was horrible for me. Leopard was much better in every way. I now run 2 Quad G5’s and 2 24″ iMacs. One G5 is running Leopard and the other is running Tiger. Both my iMacs are running Leopard. I an NOT upgrading to Lion at all. When I get my new Mac Pro (hopefully this summer if they release a new model), I’ll make sure it has Lion on it so I can run my DAW apps on it.

    • Matthew says:

      Are you not familiar with Apple OS releases? This isn’t a new OS, its an update to OSX, from when it originally came out. It adds new features and fixes bugs at the same time.
