    Try downloading it in safe mode. Hold the Shift key while your Mac is starting to start into safe mode, and then, open App Store > Purchases, and download Mountain Lion.

  • Error when trying to install Mountain Lion - says hard disk is damaged :(

    I downloaded and installed Mountain Lion on my iMac today - without any problems. But when I downloaded it to my Macbook pro (bought 2010) I get an error message telling me the installation cannot continue due to hard disk error My harddisk was fine before the installation, to my knowledge ...
    Of course I tried disk utility (during the installation) and it tells me the disk needs to be repaired but I can´t choose "Repair disk" since it is grey (no write permissions it says). What can I do? I really need help!!!

    I rarely post, however, because of a major screw up with Mountain Lion, I will.  I have been using mac computers since 1987, have obviously installed and upgraded multiple OS new and upgrades and never, I mean never had a problem with any of them, until now.  The install stalled with the message that the hard disk needed repair.  I thought all of my data was lost, except for time machine backup, which was not as current as it should have been.  Losing that data would have been a royal pain. 
    Went through the restore OS from Time Machine, then tried to repair the disk with apple disk repair utility.  Not repairable.  Why?  I still don't have a clue.  After reading multiple threads, decided to go ahead and buy DiskWarrior.  This was a weird experienc.  Loaded it onto external hard drive, hooked my MacBook Pro as Target disk.  Loaded in DiskWarrior as hardware probelm.  ????  Immediately went online to see what advice about this message.  Looked like a massive coincidence had hit my laptop.  Worked perfectly until loading Mountain Lion, the decided to have hard disk melt down.  Suddenly, DiskWarrior indicated it was ready to rebuild my directory.  The hardware warning was gone.  A few minutes later, directory repaired.  Rebooted, same problem.  Can't load OS X, need to repair hard disk.  Apple disk repair still unable to repair disk.  Used DiskWarrior, repaired it no problem. 
    Deleted original OS 10.8 dmg.  Rebooted and downloaded fresh copy of OS 10.8.  This time install went flawlessly.  Mountain Lion transferred all info flawlessly.  Mid 2009 MacBook Pro running flawlessly and actually more smoothly now than in Lion.
    1.  I think original download was somehow corrupted and that is what screwed up the disk directory.
    2.  I do not know why apple Disk Utility would not repair the disk and Disk Warrior would.  Expensive fix, but ultimately worthwhile.  Did it mysefl and did not have to mess with "Genius" bar.
    3.  I will never go so long without backup again.  That was a big mistake.
    My advice:
    1.  Be sure you have smooth download of entire Mountain Lion file, if not, start over.  My download was paused a couple of times.
    2.  If the install is messed up and you need Disk Repair, buy DiskWarrior and repair directory, it works flawlessly.  If it initially says your disk has hardware problem, wait a few minutes while it finishes entire evaluation.  It may well disappear like mine did, then actually repair the directories without a problem.
    3.  Be sure you have deleted old OS 10.8 Install file and load fresh one.
    4.  Install OS 10.8 and you should be OK.
    5.  Good luck.
    Mountain Lion seems to have some problems, but many of them may be due to server overload at apple, delayed download with incorporated unrecognized code problems.  If there is any delay, start over and get a smooth download.
    Disk Utility is too light weight.  Apple needs to beef it up.  This is my biggest complaint.  Apple utility should be able to fix disks.  We should not have to spend $100 to fix a disk, but there you are.
    Once fixed however, back to usual beautiful, flawless apple experience.

  • "The product distribution file could not be verified. It may be damaged or was not signed." error while downloading OS X Mountain Lion

    I paid for the Mountain Lion, was downloading perfect. When almost 1 gb of downloading was left then this error occured "The product distribution file could not be verified. It may be damaged or was not signed." and stopped downloading and now every time i try to download it this error occurs
    What should i do now, i paid for it and couldn't even download it now.

    You'll need to re-try the download.
    If you have a flaky network connection, or if you're behind a proxy server, there can be issues.
    The App Store knows you paid so you won't have a problem trying to re-download, but you will have to re-download.

  • Getting S.M.A.R.T. when trying to install Mountain lion. Hard drive works pretty well. I understand that many users have been facing the same issue. Has apple patched it yet?

    I'm getting S.M.A.R.T. error when trying to install Mountain lion. Hard drive works pretty well despite the Failing status. I understand that many users have been facing the same issue. My hard drive was/is working perfectly. Has Apple patched it yet?
    Has someone found a solution which is not replacing the hard drive which works just fine? Or Is anyone aware of a procedure that can force the installation despite the S.M.A.R.T error? Below details of my hard drive

    If you haven't done so, run Disk Utility  /Applications/Utilities

    Hopefully you have all your important data backed up just in case.

  • When attempting to buy mountain lion, "unknown error has occurred" is message when entering ITunes ID and password and am unable to download app.

    "Unknown error has ocurred" message when trying to buy Mountain Lion on my MacAir laptop.  Apple ID and password are operative with IPhone device but will not operate with ITunes purchase of Mountain Lion and ITunes advisor simply referred me to these discussion communities.  What to do???

    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Select "/var/log/install.log" from the file list on the left. If you don't see that list, select

  • Since downloading OS X Mountain Lion my WordSearch9 will not open. I got a message that X11 was not supported and directed to a sited to download XQuartz. Now when I try to launch WordSearch9 I get a message "X11 cannot be found.

    Since downloading OS X Mountain Lion my WordSearch9 will not open. I got a message saying that X11 was not supported and directed to a site to download an update "XQuartz" which I did. Now when I try to launch WordSearch9 I get a message "X11 cannot be found". I did follow the instructions to download and install XQuartz, but there still seems to be a problem. Anyone have an idea?

    Your report indicates Mountain Lion, but your footer indicates Lion.  I'll assume you're on 10.8.2; on the current Mountain Lion version.
    Rebooting is fine.
    The posted diagnostics look like there might be a problem with the Xquartz install, or it is not starting, or it's not authorized for the sandbox.  (But I don't know enough about that to be certain.)
    Try launching X11.app directly from your Applications > Utilities folder, and see if that works, or if shows any dialog boxes, or that reports any errors.
    If you had an Xquartz kit installed and it's not the 2.7.4 (current) Xquartz kit, then please update to that version.  (I'm assuming that site is where you got your Xquartz kit from, too.)
    I'd also suggest also discussing this more directly with the Xquartz folks via mailing list or the IRC channel, or collecting up the Xquartz logs and then posting a bug over at the Xquartz site; here are the details on bug reporting for Xquartz.

  • I downloaded the mountain lion from the app store and it downloaded. when i installed the mountain lion it said that the hd disk is broken and cannot be repaired, and the other disk doesnt have enough space!

HELP and i cannot return to my desktop with the old sofware so i cant use my computer normaly

    This error means that your hard drive is badly corrupt and cannot be repaired by Disk Utility. Since you say you don't have backups, this is very bad news. You may already have lost data irrevocably.
    First order of business needs to be backing up whatever you can, but this may be difficult to do if the machine won't start up any more. See step 1 of the following post:
    https://discussions.apple.com/message/21614450#21614450
    Once you have backed up your data, you can address the other issues.
