Cannot install Mountain Lion as installer sys the target drive I have selected is using Time Machine. The target drive I selected is my internal drive.

Yes, you’ll be able to do that.

    You do meet the hardware requirements. Otherwise you wouldn't have been able to purchase ML.

    Cannot install Mountain Lion on my hard disc, as I keep getting the message" 'This disk is used for Time Machine backups'. Which it isn't - I don't use Time Machine

    Check to see if you have a folder named "Backups.backupdb" at the root level of your hard disk. That can cause this error message.

  • When trying to install Mountain Lion I get an error message, Failed, recovery can't be created

    When trying to install Mountain Lion I get an error message, Failed, recovery can't be created

    My Mountain Lion install failed for the following reason:
    OS X can't be installed on the disk Macintosh HD, because a recovery system can't be created.
    The message went on:
    Visit www.apple.com/support/no-recovery to learn more.
    The page is about a different failure, but I'm assuming the reason for my failure is this one:
    The disk has a non-standard Boot Camp partition setup, in which further partitioning was performed after running Boot Camp Assistant, or the configuration that Boot Camp Assistant created was manually modified.
    The cure involves erasing the entire HD and starting from scratch, which in my case would involve backing up both the Mac and Windows sides, setting up Boot Camp again, reinstalling Windows XP and recovering everything from backups on both sides. I would rather not have Mountain Lion than go through all that, and I think it's unfair for Apple to expect me to.
    Because I don't recall doing anything off-piste when I set up Boot Camp in the first place (for a start, I'm not clever enough), I consider this episode an inadequacy in the Mountain Lion installer. As I won't be using the download, is it possible to get my money back?

  • Cannot install mountain lion keep getting "This disk is used for Time Machine backups" when trying to install, HELP!!!

    Ok i currently have Lion on my early 2011 15" MBP. When i try to install Mountain Lion to my mac HD it keeps telling me I cannot because its used for time machine backups. I have done a search and I know I have to delete the backups.backupdb folder but I cannot find it for the life of me. If anyone can help I would really appreciate, thanks!
    Nik

    If you double-click on your hard drive icon the Backups.backupd folder should be on the root level of your drive. Sometimes OS X gets confused and incorrectly puts a Backups.backupd folder on your hard drive. That folder should only appear on a drive used for Time Machine
    If you can't find the Backups.backupd folder try using the free EasyFind with both Package Contents and Invisible Files & Folders checked. Search for "Backups.backupd" without the quotes on your hard drive (default selection), not your Time Machine drive. Right-click on the search result and choose to Reveal in Finder. Click on the link that kisuke3 provided and follow those directions
    If you can't find a Backups.backupd folder anywhere try booting into Safe Mode by holding down the Shift key right after you hear the startup chime. Keep holding the Shift key down until you see the Apple Logo. The progress bar that appears indicates the progress of the file check that Safe Mode automatically does. Give it time to finish.
    Reboot normally and see if the ML installer will work. If it does wait until Spotlight is finishing indexing before turning Time Machine back on.

  • Cannot install Mountain Lion on Mac Pro 4,1 (2009) - can anyone help?

    Hi All,
    I have a 2009 Mac Pro - purchased 2nd hand in January. I am trying to install Mountain Lion and had the same issues as other Mac Pro 4,1 owners have had.
    I've tried installing from the installer exactly as downloaded from the App Store - this results in a grey screen, and I have to re-install Snow Leopard to get the machine running again.
    I've tried creating a bootable USB stick. This boots into the installer, but then I get the message "Mac OS X could not be installed. Try reinstalling." which is the most ridiculous error message I've ever read.
    I've unplugged all peripherals except keyboard/mouse and one monitor. I've removed all extra drives from inside, except for the system drive. I've removed the wireless card. And I still can't install Mountain Lion. If it had cost more than £14 I've be rather upset at the moment.
    Does anyone have any sage advice that will get me running ML?
    I do have a full error log I'm happy to share, if that will help.
    Thanks in advance!

  • Cannot install Mountain Lion on empty drive

    I'm helping my father try to install the OS onto a newly installed internal drive on his Mac Pro. He's trying to install Mountain Lion, which is the same OS X generation as his usual boot drive (which is remaining in the system—the new drive is getting an OS as a backup boot drive).
    The problem is that the Mountain Lion installer, downloaded from the App Store, refuses to install on the new drive. The drive, which is formatted but otherwise empty, does not appear as an available drive to install on.
    My father believes that this is related to the note in the System Requirements saying that the Mac being installed on must already have Snow Leopard or Lion installed on it. I'm not so sure, but it's a valid question: can Mountain Lion be installed only as an upgrade, requiring an existing OS install on the actual drive being installed to?
    My interpretation of the listed requirement is that you have to boot from Snow Leopard or later to do the install, because the installer has to contact the App Store, but the requirement is worded ambiguously enough that it could mean that the drive itself must have Snow Leopard or later on it. It doesn't make sense to me, though, for this installer to be useable only as an upgrade; there are numerous situations under which a person might need to install an OS on an empty drive.
    So there's two questions here: can Mountain Lion be installed on an empty drive, and are there other likely reasons for the installer to not offer the drive in question as an available destination?

    Yes, it can be installed on an empty drive but the drive must be properly partitioned and formatted first. The HD must have a "GUID Partition Table" which you establish when you first partition the drive (use the Options... button), and it must then be formatted Mac OS Extended (Journaled). Boot from his current drive and run the ML installer from there with the new drive as the target. Note that if you haven't actually downloaded the ML installer yet, when you do, it automatically starts running but you get the choice to continue and choose the drive.
    Snow Leopard or Lion are mentioned as prerequisites because the days of install DVD's are over; the installer must be downloaded and at least Snow Leopard is necessary to get to the App Store to do that.

  • Cannot install Mountain Lion 10.8.3

    I have tried to install the 10.8.3 update and while it will download and restart when it has downloaded, the App icon still shows that it needs to be downloaded and installed.  I have tried manually downloading from Apple and have restarted way too many times to no effect.  I cannot install the new version of iTunes without this upgrade. I have a mid 2011 iMac 2.7 gHz Core i5.

    Give this a try:
    Repair the Hard Drive and Permissions - Lion/Mountain Lion
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
    After this is completed download and install OS X Mountain Lion Update v10.8.3 (Combo).

  • Cannot install Mountain Lion because of a S.M.A.R.T error.

    I just bought the Mountain Lion Upgrade, (Mac OS X 10.8) from the app store, and I can't install it because of a S.M.A.R.T error. How can this be resolved???

    If you are getting SMART errors immediately backup the drive.
    If the system is still under warranty (or AppleCare) contact Apple to make plans to have the drive replaced. If not you have to decide if you want to get the drive replaced or replace the system. How old and what is the system?
    SMART errors cannot be repaired you need to change the drive.

  • Cannot install Mountain Lion due to an application error

    I have a late 2010 MBP. I had 10.6.7 and had updgraded it up to Mountain Lion.
    Lately, I was having some issues with my computer (i.e., failure to startup, or move past the grey screen), so I decided to reinstall my system.
    I accessed the partition, and tried to restore my system to a previous backup, but it didn't work. After trying a few times, I decided to reinstall Mountain Lion to my system. However, each time I try to run the setup, it gives me an error which says "Cannot run installion due to an application error. Please try again later."
    Of course, I can't downgrade my mac 10.6.7 as well.
    Help?

  • Cannot install Mountain Lion - my iPhoto won't quit and Mountain Lion won't let me do a force quit

    I'm trying to upgrade to Mountain Lion but when it ries to quit all programmes to install my iPhoto won't quit as albums are being sync'd.  I try to stop and quit but it won't.  I then try to force a quit and Mountain Lion won't let it.  help!

    if you don't mind interrupting the album sync, you can do a hard shutdown of the mac by pressing and holding the power button down for 10 seconds to make sure it's all the way off.
    you can then do SMC reset which is described in the following article:

    after doing this turn on the mac, click on the black apple then force quit and make sure all apps are closed
