Location of Mountain Lion Download?

For some reason yet to be discovered I always seem to have issues downloading large files on my Mac.
I have a work around where I download the SW packages at work and save to a USB thumb drive and then copy and install on my Mac.
Can someone tell me where the Mountain Lion download is located and what I need to do if I already have the purchase recoreded in the apps store?
Thanks,
Steve

Mmmmm now thats a problem!
Any ideas why when I download it tells me that I have a "hash mismatch" problem. I guess that the checksum is failing????
I've noticed in the past that large downloads seem to get corrupted.
Any suggestions or workarounds?
In the past with major updatyes that have don this then I've gone to the downloads page and downloaded from my PC at work and then copied the .dmg to my mac and its worked.
This problem only seems to have started when I moved to a cable modem from DSL?? not sure if this is a clue or not
Thanks

  • Mountain Lion download on multiple (family) computers

    Downloaded OS upgrade to Air. How do I install to family iMac? Understood that the license for the Mountian Lion allows download of the OS for up to 5 family devices.

    If you purchase Mountain Lion from the App Store then you can install it on all the computers you own. There is no limitation as long as you own them all.
    You must have Snow Leopard 10.6.8 or Lion installed on each computer. Sign in to the App Store from each computer using the same Apple ID used to purchase Mountain Lion. You will then be able to re-download for free.
    Or if you saved the Mountain Lion installer applcation then you can do this:
    Make Your Own Mountain/Lion Installer
    1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
    2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
    Open Disk Utility in your Utilities folder.
    After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
    3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
    4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
    Double-click on the InstallESD.dmg file to mount it on your Desktop.
    Open Disk Utility.
    Select the USB flash drive from the left side list.
    Click on the Restore tab in the DU main window.
    Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
    Drag the mounted disc icon from the Desktop into the Source entry field.
    Double-check you got it right, then click on the Restore button.
    When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
    Note: The term Mountain/Lion used above means Lion or Mountain Lion.
    You now have a Mountain Lion installer you can use for each computer now or whenever you need to reinstall Mountain Lion.

  • How many machines can I install on with one Mountain Lion download?

    I want to upgrade to Mountain Lion, but I have both an iMac and a MacBook Pro.  Do I have to buy two Mountain Lion downloads - one for each, or can I somehow download twice after paying once?
    Judy

    Actually, having made the same claim a couple of days ago and being proven completely wrong, I have a certain responsibility to correct you by mentioning that there is no limit to how many machines ML can be installed on, as long as you own or control those machines.

  • Mountain Lion download problems with Lion 10.7.5 (no VirusBarrier issue)

    I have a mid-2009 Macbook Pro. From the factory it came with Snow Leopard but has since been upgraded to Lion OS X 10.7.5. I do not have VirusBarrier, I am writing from a recently clean-installed Lion.
    I have now been troubleshooting my Mac for several days. When I wrote first, I had an issue with Safari having been damaged and so I wasn't able to reinstall Lion - but after a certain extremely helpful community member I finally succeeded in installing Lion.
    But the issues with the App Store still persist. All my Mountain Lion downloads fail, getting the error message "can't verify, might be corrupted" what many here have also been getting. However, most solutions were related to VirusBarrier (which I don't have), or /var/folders errors (Console does not show any var-related errors).
    So if it's not a var-related issue, or related to firewalls or virus softwares (I have disabled the Firewall and I have no virus software installed), what could it be?
    When the download and install of ML failed last time, Console showed the following messages:
    11/30/12 11:54:44.617 AM com.apple.SecurityServer: Failed to authorize right 'system.install.app-store-software' by client '/System/Library/PrivateFrameworks/PackageKit.framework/Versions/A/Resources/in stalld' [235] for authorization created by '/System/Library/CoreServices/Software Update.app' [567]

It may have been corrupted or tampered with during downloading.}
    ...and a bit later, upon re-starting the download:

    Problem elimination:
    * I don't think this is a router-related issue: I have downloaded and installed other softwares outside App Store successfully
    * As said, I don't think this has anything to do with Firewall or Virus settings
    * Nor has this anything to do with /var/folders as far as I can tell
    What I've tried so far:
    * Repaired disk permissions several times
    * Rebooted
    * Restarted App Store
    * Following one advise found on the net, I deleted preflight.pfpkg just in case
    * All the time I have made sure my OS has the most recent Software Updates installed (most of them downloaded successfully, while with Safari and OS 10.7.5. I had to try several times before they were downloaded succesfully)
    I just reinstalled my OS X Lion, only to use it to jump on to Mountain Lion - so I am pending my migration until ML is installed. I would like to fix this soon, since I'd like to get the migration done and my real work started. I would really appreciate your help.
    I'm not very adept at using Console or Terminal to troubleshoot, so if someone could guide me through the problem identification, that would be great. Unless someone already knows exactly what's going wrong and can show me a working solution - that'd save my day!
    Thanks!

    In cases like this, if you have an Apple store near by, they will most likely install the OS free of charge for you, if you can't bring your Apple ID along to prove you've paid for it.
    Would that work out for you?

  • HT4718 Can't find iLife after Mountain Lion download?

    After my mountain lion download (done by a genius at the apple store so I know I didn't mess it up!), ilife isn't here. It's also not under the "purchase" section of the app store like support.apple.com says it should be. help?

    New Macs come with iLife. However, if you did a clean install you're not going to have iLife.
    However, the original install disk that came with your Mac should have an iLife installer included.

  • Slow internet after mountain lion download

    web pages open slowly or not at all after mountain lion download

    I'm having the same problem but only at home with a slow internet service.  At work with faster internet my macbook pro works fine.  I wonder if Mountain Lion requires some minimum internet speed?  Our old macbook pro (not using Mountain Lion) still works fine with our slow home internet.  This change happened when I installed Mountain Lion.  Also I can boot from by back up disk and bypass Mountain Lion and work with my slow internet at home. ???

  • After Mountain Lion download, FaceTime is not working anymore. Any ideas?

    After Mountain Lion download, FaceTime is not working anymore. Any ideas?

    I have reinstalled mountain Lion again . This time, Facetime works when somebody calls me, and I can do calls from my Mac again. But the problem was still that I was not able to call my iPad, what I was able to do with Lion (I had one Apple-ID and two call adresses). The solution was this time to generate a second Apple-ID from the Facetime in my Mac (this doesn't affect your main Apple-ID, it's only used for Facetime). Now, it works!  ;-)

  • My OS X Mountain Lion download was interrupted and now I can't get it to download at all.

    My OS X 7 Mountain Lion download was interrupted and now I have a Mountain Lion shadow on my doc saying "paused" but I can't seem to restart the download

    If the download does not resume, then Quit the App Store app and delete the partial download in your Applications folder. Then you will have to start the download all over again from the "Purchases" section of the App store.

  • Can I stagger the OS X Mountain Lion download?

    Hello,
    Can I stagger the OS X Mountain Lion download as long as convenient?

    That depends quite a bit on the speed of the links between your computer and the servers sending the download. Your immediate link to the internet and the link from your modem/router to your Mac are ikely to be the slowest links.
    Absent information about your link speeds, "hours and hours" is the best answer I can give.

  • Help with mountain lion download

    I bought the new imac on the 1st september and with my purchase i got a free mountain lion download.

I do not want to buy the mountain lion software because i got it for free so i was wondering if there is any way i can restart the download? All advice is welcome

  • Mountain Lion download getting stuck at 79MB w/ no internet connectivity issues

    I just purchased Mountain Lion via the App Store but everytime I try to download it, the download gets stuck around 79.4MB and the download time just gets longer and longer without the download actually pausing. Pausing and resuming have the same problem, the file size just goes up to 80+MB before dropping back down to 79.4MB again. I have tried canceling, reopening the App store and re-downloading several times already without success. Please help! I went through Mountain Lion download problems in the forum but I can't find a solution. I'm downloading onto an iMac on a broadband Wifi personal home network and can surf the internet without problems and as quickly as usual. For reference, my connectivity speed at this time is usually enough to download a 300MB file in 15 mins to half an hour.

  • Mountain lion download is very slow and in-between it hangs of and starts from beginning. Is there a solution i have already purchased it can i download a torrent and authorize it

    Mountain lion download is very slow and in-between it hangs of and starts from beginning. Is there a solution I have already purchased it can I download a torrent and authorize it. Somebody pl. Help

    Exactly. Some of us don't understand the situation in India. This is a country with sickest internet speeds. The internet segment is dominated by fraudulant companies. There is no consistency that is why most of the data transfer here is through Pen drives and torrent websites. We have never seen a good downlooad speed here. And on the top of inconsistency lies the Mac book Air without a built in RJ45 port.
    If i have to do it in an internet cafe it will cost me more time and money than to purchase a Mac book air itself. Apple should start giving us software loaded flash drives at least at premium.

  • HT4569 In case of lost internet connection during mountain lion download from app store, do i have to start over?

    In case of lost internet connection during mountain lion download from app store, do i have to start over?

    How do I speed this up.  I have a fast internet connection but this is obviously not right. 
    The speed of the downlaod is dependant on the speed of your Internet connection. "I have a fast Internet connection...," doesn't actually mean anything unless you provide some numbers.
    I have a cable Internet connection with 32 Mbps download speeds, but if you have DSL, you would probably be limited to 1.5 Mbps. Some would call both of these connections "fast," but obviously one is faster than the other.
    What is the speed of your Internet connection?? Don't say, "fast."
