Unable to purchase Mountain Lion, App Store says Unable to Verify

Whenever I try to purchase Mountain Lion, a window opens saying the distribution file could not be verified, etc.  See included image, haven't found a way around it and can't make the purchase.  My software is current Lion 10.7.4 on a MacBook Pro purchased in mid to late 2010.  Any thoughts?  Thanks!

  • HT1349 Redeem Mountain Lion App Store update code

    I sent my Mountain Lion App Store update code to the wrong e-mail address and can't recover it, but registered the serial number to my newly purchased MacBook Pro. Can I have my code resent to an e-mail I actually use to redeem it and download the new OS?

  • Purchase Lion - App Store Says Already Installed

    Ok, my nephew, who knows better, downloaded Lion OSX from a sharing site.  Said he wanted to "try" it before he bought it.  Now, he wants to buy it since his mom found out what he did.  So, we went to the App Store and it says Lion is already installed.  How can he buy it so his machine is legitimate?  Is there a way for him to remove the downloaded copy he has and then do it the right the way through the App Store?
    Thanks for the help. 

    I think, but I'm not sure, the only way to uninstall the version of Lion already on that computer is to wipe/erase the drive and reinstall Snow Leopard on it. Apple does not have a method of reverting to the previous OS once the new one is installed.
    You could also buy Lion on USB thumb drive for about double the price of the downloaded version and then take the cost of it out of the young fellows allowance and or make him work it off.

  • OS X Mountain Lion & app store

    Hi,
    I have two problems on app store. One is that on apple website, it once said that customers who purchsed a Mac within one month are allowed to update OS X Mountain Lion for free. I just bought a Mac air last week in an authorized apple store. So I went to app store to download Mountain lion. Because there is only a buy button,( I couldn't find any buttons for those customers) I end up purchasing a mountain lion instead of getting it for free. When I realized in the first second, I clicked on pause button to stop downloading. I am wondering, can I get my money back or can I cancel that purchase because I didn't download it to my laptop and I wasn't intended to buy it. Also, where can I find that priority to download Mountain lion for free?
    My second question is that I need to purchase a Microsoft office words and powerpoint on app store. So when I typed them on the search bar, there were templates for MS words and templates for MS powerpoint coming out. Since they  were the top two and associated with words and powerpoint, I purchase them. But when I tried to install them on my Mac,they just didn't  look like regular words/powerpoint. For templates for MS words, there is no workspace and doesn't look like a document anymore. So I am wondering, are they regular words/ powerpoint software? If I installed them incompleted, how should I install them correctly? What is the correct name of those software on App store? Thanks.

  • Mountain Lion App Store Download Error

    Trying to download Mountain Lion from App Store. It tells me that program size it's only 53.25 MB. When download completes (partially) tells me that download can´t be verified... Please give me a hint. Thanks

    I encountered the same error "…can't be verified…"  on my 2010 MBP too. Tried six times and finally I could get it installed. Here's what I did:
    Went to "Users & Groups" in System Preferences, checked that the Apple ID specified for the current user is the same Apple ID I used in the download purchase of ML from the App Store.
    Rebooted in Safe Mode.
    Went to Disk Utility -> Repair Disk Permissions
    Downloaded ML at midnight (and the download was significantly faster!)
    Rebooted in Normal Mode.
    Ran the ML Installer.

  • Downloading from Apple Mountain Lion App Store Hangs 2901 router

    Cisoers,
    I have a repating 2901 router failure when people attempt to download Apple Mac OS X Moutnain Lion upgrade from App Store.
    The 2901 just hangs following getting a series of ZBFW packet drop failures:
    001928: Jul 26 22:37:18.783 UTC: %APPFW-4-HTTP_PROTOCOL_VIOLATION: HTTP protocol violation (0) detected - session 192.168.223.109:49310 184.25.254.67:80 on zone-pair ZP-PRIVATE-OUT class ccp-protocol-http appl-class ccp-http-blockparam
    001929: Jul 26 22:37:20.871 UTC: %APPFW-4-HTTP_DEOBFUSCATION: Deobfuscation signature (15) detected - session 192.168.223.109:49369 66.235.138.44:80 on zone-pair ZP-PRIVATE-OUT class ccp-protocol-http appl-class ccp-http-blockparam

    The failure results in the ACT Light stopping to blink and the SYS Light remains on solid Green and the entire router hangs.
    I cannot SSH to it, all logging to console stops and the only way I can recover the router is by powering it off and on again.
    This is very alarming as this is a very common download site and I am finding router is hanging consistently and repeatly when people go there.
    Does anyone have any suggestions?
    This looks like a major bug in IOS.
    Regards,
    John.

    Hi Peter,
    thanks very much for the suggestion.
    I did a check on the 2901 and the config has very small (default) allocations:
    parameter-map type ooo global
    tcp reassembly timeout 5
    tcp reassembly queue length 16
    tcp reassembly memory limit 1024
    tcp reassembly alarm off
    As per your suggestion I have update the sizes (the 2901 has 2GB RAM) moved HTTP application inspection back up to it overides straight tcp protocol inspection.
    parameter-map type ooo global
       tcp reassembly timeout 5
       tcp reassembly queue length 512
       tcp reassembly memory limit 16384
       tcp reassembly alarm off
    I have a couple of further Apple Mac's that need to be updated to Mountain Lion so will test download again when updating these machines.
    Cheers,
    John.

  • HT5568 Error with Software Update on Mountain Lion App Store

    A software update, of Safari 6.0.2 & iPhoto Update 9.4.2, failed with the error:
    An error has occurred
    This operation couldn't be completed
    (NSURLErrorDomain error -3001.)(102)
    Is this my problem or their problem?

    Hello - yes, the Software Update function is incorporated to the App Store as Updates. It is somewhere written on the Apple page, forgot where. I also do not want to know :-) As long required and recommended Upgrades will be offered in or another way, i am fine.
    I also just installed ML, almost during a coffee break and meeting, and continuosly worked, I am so far fine. One application, MindMap, required Java SE 6. Within 2 minutes it was installed. Need two attempts, maybe caused by overload of system now.
    The Indexing took some time, but it was within an hour finished.
    So far, I am okay with ML - nothing to complain. Some features will be enabled with iOS6 for the iPad and the integration of different functions into the cloud.

  • How to enable the (Mountain Lion) App Store Debug Menu

    The Mac App Store Debug Menu:
    Quit App Store [ App Store ] File… Quit or [ ⌘Q ]
    Open Terminal
    defaults write com.apple.appstore ShowDebugMenu -bool true
    Relaunch App Store

    I'm not sure what you mean? I had problems with App Store, I found this info, I posted it in Discussions so it would be easier for others to find. What's up with ''one up splurben"?
    Would you prefer I posted this outside Discussions? :-S

  • HT204088 Report a problem not working in Mountain Lion App Store

    When I try to report a problem with an app, instead of showing me the menu as in this article, it opens my browser and sends me to the apple UK support page! (I'm in Mexico by the way so this *****).
    So I don't know what to do to report a problem with an app and get a refund

    Also just noticed that I can switch FROM a full screen app TO any other (non-full screen) app in another space and it does switch to that space. But can't then switch back or to any other app on another space, as expected.
    Plus if you have mutliple full screen apps open then you can quite happily switch between them! So I guess Apple expects us to run everything full screen?!
    This had better get fixed for 10.8.3... although re the Parallels mention - I have recently upgrade to PD8 so perhaps not coincidental? Can't recall if the prob first happened before that though.

  • HT1338 i have a really old mac book with mac osx 10.6 and I cant purchase mountain lion in the app store. it says its not compatible with this computer. what can i do

    I have been trying to purchase mountain lion from the app store and it doesnt let me. I keep getting mobile me in the system preferences and i want to upgrade so i can link this mac book with my icloud account and devices. How can I uograde to mountain lion?

    Choose About this Mac from the Apple menu, click on More Info, and check the model identifier against the following, which are the earliest models capable of running 10.8:
    iMac7,1
    MacBook5,1
    MacBookPro3,1
    MacBookAir2,1
    Macmini3,1
    MacPro3,1
    Xserve3,1
    If your computer is incapable of running 10.8 but has at least a Core 2 Duo(not Core Duo) CPU and at least 2GB RAM, phone the online Apple Store and order a download code for Lion.

  • I'm trying to reinstall Mavericks on used Macbook Pro. When I log in to my Apple ID, it says it was not the same ID used to purchase Mountain Lion. I need to change user/admin as a lot of the folders and apps are in Chinese!

    I'm trying to reinstall Mavericks on used Macbook Pro. When I log in to my Apple ID, it says it was not the same ID used to purchase Mountain Lion. I need to change user/admin as a lot of the folders and apps are in Chinese!

    The first thing you should do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. How you do that depends on the model. Look it up on this page to see what version was originally installed.
    If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc, which you can get from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. I suggest you install as much memory as it can take, according to the technical specifications.
    If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for some MacBook Air models. If you don't have the media, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
    To boot from an optical disc or a flash drive, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
    If the machine shipped with OS X 10.7 or later, you don't need media. It should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
    Once booted from the disc or in Internet Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive, which is what you should do.
    After partitioning, quit Disk Utility and run the OS X Installer. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
    You should then run Software Update and install all available system updates from Apple. If you want to upgrade to a major version of OS X newer than 10.6, buy it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.
    If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Apple customer service has sometimes issued redemption codes for these apps to second owners who asked.
    If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able toauthorize it under your ID. In that case, contact iTunes Support.

  • Why would it state under the "more about this mac" that i already have10.8.3 and then in the app store say i need to "resume" do you know what i mean? is it possible i already did download mountain lion entirely once? I am confused and don't want it twice

    This is cause by the way the App Store checks to see if an application is installed on your system.
    Basically when an app is installed it is in the Applications folder and this is where the MAS looks for them. So it looks at your purchase history for the apps you bought and looks in the Applications folder to see if they are installed. If an app is in your purchase history but not in the Applications folder the MAS says you need to install it.
    For normal apps this works fine but the OS doesn;t install into the Applications folder. So the MAS sees you have Mountain Lion in your purchase history but it's not in the Applications folder and so it says you need to download it.
    Hopefully one of these days Apple wil fix this.
    regards
