Mountain Lion Failed to Install

In the middle of the install OSX mountain lion jumps to a recovery screen and cancels the install. When I restart the computer I am able to go right back to my normal desktop with nothing lost.
Any thoughts- There is no error message.

I'm having a similar problem installing Mountain Lion on my older MacBook Pro (mid to late 2007).  When I begin the install and choose my internal HD, I get the message "This disk is used for Time Machine backups."  That's not true - I have Time Machine completely turned off.  I've gone to Disk Utility and used Verify and Repair Disk. It did some repairs and now shows that the disk is fixed. However, the new system will still not install. I don't have File Vault on either.  Any suggestions for me?

  • 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....

    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

  • OSX Mountain Lion fails to install on 2009/2010 MacPro

    I have a Dual Xeon dual cores MACPro and just got the new OS however it fails to install on the MACPro with the error message  "Mountain Lion is not compatible with this computer"
    My current OS is 10.7.4, does anyone have any imput on this issue has this been seen by anyone else?
    Any help would be apreciated.

    Macs that can be upgraded to OS X Mountain Lion
    iMac (Mid 2007 or newer)
    MacBook (Late 2008 Aluminum, or Early 2009 or newer)
    MacBook Pro (Mid/Late 2007 or newer)
    MacBook Air (Late 2008 or newer)
    Mac mini (Early 2009 or newer)
    Mac Pro (Early 2008 or newer)
    Xserve (Early 2009)
    I'm guessing that you have a Mac Pro 1,1 or 2,1 model from 2006/7. They cannot run Mountain Lion.

  • Mountain Lion fails to install

    I have been trying to install mountain lion for a while now. just donloaded the updated version but it still fails.
    it fails after trying to install it and says the system will now restart and return to the previous OS (lion).
    I have tried booting to the recovery HD to see what i can do but it just starts installing ML but doesnt seem to go anywhere.
    Tried a clean install but it doesnt come up with the options to format, it just tries to install but fails.
    If anyone knows of any other options for me to try it would be mighty helpful.

    I'm having a similar problem. The update downloaded quickly. It looked small. The computer asked to restart and install. I've been looking at the spinning gray spokes for about an hour. Twice the computer has gone to sleep, and I had to wake it up. 
    I'm using a FileVault disc protection and I'm afraid of forcing a restart. I'm not sure a full install of mountain lion took this long.... But I was able to walk away from that. Here, it seems to go to sleep on me if I don't periodically poke the keyboard.

  • Mountain lion fails after install

    Anybody have any solutions to Apples debacle on Mtn lion install issues? After attempting to install twice, all i get is the spinny clock and my imac quad core i7 never boots. Ran disk utility before I ever installed, and ran it twice after in recovery mode. No problems on internal drive. DVD drive seems to have mysteriously bought the farm though. Booted in verbose and I did get one error mentioning boot cahce control undnable to open no such file or directory. Thought that was from the old days of leopard. Argghh...

    Update
    Took my imac to Genius bar and they could not solve the problem either. So they wiped the drive and reinstalled Mtn lion 10.8 via net boot. Problem solved? Well, yes up until I did system update 10.8.1 and right back into the fire again. Same problem of not booting. Holding down shift key didnt fix it either. Back to Apple which said don't update to 10.8.1, wait until 10.8.2. They are seeing system hangs. Think I will go back to Snow Kitty. Mtn lion is not ready for prime time yet.

  • Mountain Lion won't install on 10.7.4. Suggestion from Apple is to completely erase harddisk and install Leopard Snow Leopard Mountain Lion. Is there no other way to install Mountain Lion

    Mountain Lion won't install on 10.7.4. Suggestion from Apple is to completely erase the harddisk and install Leopard > Snow Leopard > Mountain Lion.
    Is there no other way to install Mountain Lion?

    I tried and failed for several hours to install Mountain Lion, and was repeatedly getting the "Recovery System" cannot be created error.  I tried all the tricks: resizing the drive partition, booting from an external boot drive, all to no avail.  After reading other users struggling with the same issue, I had determined it to be a boot camp drive error.  However, I didn't want to have to erase and begin anew when I came upon a possible solution.  I had long ago renamed my boot camp drive with a "." (".windows" for me) in order to avoid having the partition show up on my desktop.  So, I boot into windows and renamed the c: drive without the "." ("windows"), and reboot into os x.  The install then went off without a hitch.  I hope this will be helpful for others struggling with this issue that may have renamed their boot camp drives in a similar manner.

  • Mountain Lion refuses to install on Hard disk because it is used for Time Backups. I have mounted a different disk for tame backups and still, I cannot install the OSX. What do I do?

    I donwloaded the Mountain Lion OSX and it would not install because it said that the hard disk is used for Time Backups. I then mounted a separate Hard Disk and started running the time backups on it.
    Still, the Mountain Lion would not install on the main hard disk.
    How do I convince it that the haerd disk is no longer used for time backups?

  • Mountain Lion can't install but won't let me quit the installer!

    Mountain Lion can't install but won't let me quit the installer! How can I get back to the desktop?

    I was having the same problem with my iMac. Couldn't left click with the wireless mouse, i tried all the steps above to no avail. I then tried to use another mouse, this time bluetooth and still had the same problems. I decided to see if my trackpad, which sits in the corner of my desk and never gets used, and then i realize that my cat is lying on top of the trackpad which was causing my problem the whole time.
    I hope your fix was as simple as mine.

    iCloud isn't syncing them on your phone.  You simply added the email account to your phone and enabled calendar and notes syncing with the email provider, and the calendar and notes appear in the calendar and notes apps on your phone.  You can do this with Gmail, Yahoo and other IMAP account.  iCloud email is just another IMAP account, but syncs notes with Apple's iCloud server just as Gmail syncs notes and calendars with Google's server.
    iCloud didnt' set up a non-iCloud account on your Mac.  When you check Mail in System Preferences>iCloud, it only creates an iCloud email account.  You can also add other email accounts to your Mac by going to System Preferences>Mail,Contacts,Calendars and clicking on the "+" sign on the bottom of the left sidebar.  If you added these other email accounts to your Mac before you upgraded to Mountain Lion, these were simply maintained on your Mac after you upgraded.

  • Why does my iMac with Mountain Lion fail to print.

    My iMac with Mountain Lion fails to find my 2 networked printers on 50% of the occasions I try to print.  Even though I have earlier switched the iMac on, the only way I can get the iMac to see the printers is to restart the iMac?  After that I have no more probs.  Leaving the iMac on standby overnight doesn't seem to help as the problem frequently re-occurs the next day
    The Brother Laserjet printer and iMac are cabled to my router, while the HP Photoprint uses wi-fi connection. There is a PC/Windows 7 also on the network which shares the printers.
    I seem to get no help from the Printer utilities in system preferences.
    Any suggestions what I need to do to eliminate this apparent breakdown in communication between the printers and my iMac.

    Hello Mike17swr,
    Thanks for the post. I'm not sure which model of Photosmart printer that you have connected, but I have included a link below with some great t-shooting steps to help identify the issue.  Good Luck!
