    Mountain Lion fails to install saying it cannot create the recovery; I had a similar problem with Lion and the Apple Store that helped me resolve it gave me an installable version of Mountain Lion on a flash drive for my inconvenience....is there some trick I am missing or do I need to make an appointment with a genius...

    I have the MacIntosh volume and the Boot Camp partition only.  I know that when I installed Lion, I had to go through a whole back-up and recovery of Windows and then re-format the drive. 
    The tech at the Apple Store had a previous life as a MSCE and was very helpful.  I believe he even said that I should not have htis problem with Mountain Lion which is why they gave me the flash with it onboard.  I was in the process of starting a new job when I went to Lion, so I have waited to do this next and probably last upgrade to this old MBP since I doubt Apple will support this MBP in Maverick. 
    I do not have another installation, so that is not an option.  I will try to create an external, I have plenty of hard drives around and see if I can get it done that way.  It might take me a week or two to get back to it, but I will comment back upon completion of that effort.  Thanks for your help....Dave Iverson

  • Why does my Macbook Pro keep shutting down during installation of OSX Mountain Lion?

    Why does my Macbook Pro keep shutting down during installation of OSX Mountain Lion?

    Hmm, good luck then!
    I'm pretty much exactly on the opposite side of the planet, but I've been to Vermont and remember its rural beauty well. However, I can't imagine you having the only Internet connection within a reasonable radius (where "neighbors" hanging off the same ISP don't count). Uh, that note only if your wired connection to the router produces no good result, either...

  • HT4827 comment désinstaller OS X mountain Lion

    Comment désinstaler OS X Mountain Lion et retourner a OS X lion 10.7

    To uninstall Mountain Lion and return to Lion, first check if you have a Mac that supports Internet Recovery > http://support.apple.com/kb/HT4904
    If you have a Mac compatible with Internet Recovery and you purchased Lion (or it came with your computer), it's easier to install Lion:
    1. Make a backup of your data without using Time Machine.
    2. Press Command, Option and R keys while your Mac is starting to start into Internet Recovery, and open Disk Utility.
    3. Select Macintosh HD in the sidebar, go to Erase tab and erase the disk.
    4. Close Disk Utility and install OS X. OS X 10.7.5 will be installed on your computer

  • Stalled installation on OSX Mountain Lion.

    While upgrading to Mountain Lion, I get as far as "Preparing to install. Your computer will restart automatically" and that's all. Even left overnight, I found it still there in the morning. Everything else seems to work fine. I would like to complete the install and move on. MBP 13" Late 2011.

    Apple are revamping support, you'll see something like this - select Apps and Software etc:
    ...next screen should have Purchases, Billing and Redemption links.

  • HELP!!! "Restart" problem after installation of OS Mountain Lion

    Dear Apple People,
    I have upgraded my Macbook Pro 13 (bought last year) from Leopard to Mountain Lion. After some days my computer stopped to start normally and restarts every minute. Please see attached the photos. I have searched other topics and internet, tried to repair disks and other tools, but nothing helped...
    I would (and of course other many people who faced this problem) aprreaciate if you could give us detailed instructions how to fix this problem. It is not fair that we have installed new software and even paid for it and now cannot use it...
    I am looking forward for your prompt action!
    Thank you.

    I found it! -  under Users/....
    So now i will back up all these files.
    What should I do then?
    Follow the "step 3. If you have a backup, press Command and R keys in boot, open Disk Utility, erase the disk and install OS X" whic you have suggested earlier?
    Do i need to have cd or flash drive to install OSX or is it enough to have internet connection?

  • How to stop the installer and make a USB version of OSX Mountain Lion

    Hi - I have had some serious problems with Mountain Lion and support from Apple has demanded reinstallation of OSX. With my rather slow BT Connect broadband sometimes the download takes 6-7 hours!!! Sometimes it stop as I understand BT Connect limits downloads. While I find a new ISP, can anyone advise me how to make an installable version of Mountain Lion from a USB stick . I have tried downloading the installer but it then immediately begins to install ISX ML and the disappears from my Downloads Directory. After 6 hours wait I am back to square one.
    All and any help most gratefully received. My machine is a 13" 2012 Macbook Air with 128GB SSD and 4GB RAM.

    It's easy. First, you have to download OS X Mountain Lion, so open the App Store > Purchases, and download OS X Mountain Lion. Then, when the download finishes, the installer will appear, so close it and it will stay in Applications folder. After reinstalling OS X, OS X deletes the installer, so it's important to do that.
    Finally, you can use an application like Lion Diskmaker to create a Mountain Lion USB drive > http://liondiskmaker.com After creating the Mountain Lion USB drive, to start from the USB drive, hold the Option (Alt) key while your computer is starting and select your USB drive

  • Error downloading Mountain Lion

    Hi all,
    I just bought the new imac (late 2012). I did a migration from a time machine backup and everything was ok. After that I changed my mind and tried to start with a fresh new installation of the Mountain Lion so I went to App Store. I tried to download again the Mountain Lion software and it says that I cannot download it because my computer is not compatible with Mountain Lion, which is the OS that is pre-installed.
    I tried deleting com.apple.applestore, uninstalling Virusbarrier and other cache that I found googleing. I still can't download the OS.
    Any ideas?
    Thank you!

    Since your machine came with it, you can't get it from the MAS. Restart into recovery mode and restore the OS.

  • I tried unsuccessfully to download Mountain Lion

    I tried unsuccessfully to download Mountain Lion (installer I suppose) on a MBP 17" running under 10,6,8.
    After clicking on the "dowload" buttion, ssurprisingly I vas not  asked to pay, the downloading began and lasted deveral hours as apparentlly usual, but when finished I didn't find the downloaded file.
    Though ML appears in my bought products list, .
    App store app doesn't work correctly any more, for example I can't disconnect.
    How to pay for and to reload again ML ?

    The ML installatin file "Installer OS X Mountain Lion.app" is inside Applications folder, it is not a ".dmg" file.
    I have been able to use it, although I didn't pay for it...??

  • I installed Mountain Lion from Apple and wish to delete iPhoto and re- install iPhoto.  How do I do it please

    Having trouble trying to upload a book from iPhoto so wonder if I can delete and re-install iPhoto .  I have no installation disc as Mountain Lion was downloaded direct from Apple.  Thanks

    Both partitions should be visible in Mountain Lion. What I did on my wife's computer was select the Snow Leopard partition, select iPhoto in the Snow Leopard Applications folder, and copy iPhoto to the Mountain Lion Application folder (drag and drop). I then ran Software Update and was able to download a newer version. If I remember correctly, I had to run Software Update twice to get the newest version.
    If you have the iLife 11 disc, you can install iPhoto on Mountain Lion and then update the program as I typed above. That is how I got iPhoto on my computer.
    I never had to pay as long as I was able to get an older version of iPhoto in the Mountain Lion Application.
    I hope this helps. Computer frustration is not one of my favorite things.
