Mountain lion installation crashes with 33 minutes remaining?! then goes onto os x utilities...

Help!

I put in the Snow Leopard Disk and it gets past the installation settings but when it gets to where I select the disk to install it, there's a yellow triangle with exclamation mark in it over the hard drive icon and says "Mac OS X cannot start up from this disk". Is the hard drive locked? I don't know what to do next, again any help is appreciated I'm desperate

  • Where can I find my mountain lion installer included with 2012 mac mini

    I just bought a 2012 mac mini and I want to install mountain lion on an SSD that I bought separately.  Where can I find the mountain lion installer file to create a bootable USB install drive?  When I go to the mac app store, mountain lion is not listed in my purchases and when I try to buy it, it says "We could not complete your purchase. OS X Mountain Lion is not compatible with this computer."  It's already installed on the mac mini, I just need the installer file so I can install it on my SSD.

    You might be able to simply boot into the ML Recovery HD, select Reinstall OS X and point to your SSD drive. You won't capture the InstallESD.dmg file to create a USB thumb drive installer.
    OR.... to create a USB thumb drive of your pre installed ML, you would need to redownload Mountain Lion then grab the InstallESD.dmg file and create your USB thumb drive.Here is how I've done it using Internet Recovery to get my pre installed OS X.
    Attach a USB external drive to your system. Formated as Mac OS Extended (Journal) and GUID partition table.
    Restart using Command+R+Option to boot into Apple's Recovery HD. This will get you the original version. Or just Command+R to boot into your ML Recovery HD.
    Select Reinstall OS X from the OS X Utilities menu.
    You will  have to watch the download. After it completes and your system restarts, at the black screen disconnect the external USB drive.
    After you are back to your current desktop, insert the external USB drive. There should be a single folder on the drive called 'Install Data' (I think). Find the InstallESD.dmg file and copy it to a folder on your current system (Downloads, for example).
    Follow any of the internet instructions to create a ML USB thumb drive.
    I tried this method, and while it did get me the installer image, when I restored it to an external and tried to use it to restore a Late 2012 Mac Mini, I got the same "No" symbol I did with other ML installers.
    Here are some screenshots of what was loaded onto my external before I yanked it, when the screen turned black durring the restart. The highlighted file is what I restored to my external to use to restore the Mac Mini.

  • Mt. Lion installation stuck at 4 minutes remaining = help

    Never had this happen before during an installation. I am installing from a usb drive which I made
    from my initial Mt. Lion installation so that I didn't have to tie up the servers/wait with each installation.
    I have used this drive to install Mt. Lion successfully on another laptop (I am installing on a MacBook
    Pro 2010 machine). This machine and the other I have previously installed on are all authorized on my
    account. I have seen the Time Remaining get to under 10 minutes and then jump back to a higher time
    before finishing but never seen it just stop. It has been about 45 minutes now. Thanks in advance for
    any ideas.

    Hello hughmourous,
    Thank you for participating in the Apple Support Communities.
    It sounds like your OS X Yosemite installation did not complete.
    If you have not already, and your installation did not complete, I'd recommend holding down the power button on your Mac to turn it off, and try booting into Safe Mode:
    Follow these steps to start up into Safe Mode.
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup sound, press and hold the Shift key. The Shift key should be pressed as soon as possible after startup, but not before the startup sound.
    Release the Shift key when you see the Apple logo appear on the screen.
    After the Apple logo appears, it may take longer than usual to reach the login screen. This is because your computer is performing a directory check as part of Safe Mode.
    To leave Safe Mode, restart your computer without pressing any keys during startup.
    From:
    OS X: What is Safe Boot, Safe Mode? - Apple Support
    All the best,
    Jeremy

  • Mountain Lion Installation stuck at 21 Minutes Left

    Late 2008 iMac. It has been stuck for about an hour now at 21 minutes remaining. The computer just had a new hard drive put in 2 weeks ago, and I can't imagine what is wrong. Should I try a force restart? I'm just worried that I'll erase all of the data on the computer, so what is my best option?

    Welcome to Apple Support Communities
    The only thing you can do is to restart the Mac holding the Power button. Then, start it and see if you can install Mountain Lion.
    If not, hold Command and R keys while your iMac is starting to start in OS X Recovery and reinstall OS X. You should have a backup of your files

  • Need help with Os X Mountain Lion Installation

    I have a Macbook Pro (early 2011) 2.3Ghz and Everytime I boot up my macbook this Os X Mountain Lion screen pop up but when I try to install it. A message pop up saying ‘"temperaly unavailable try again ‘later" and sometimes "please contact apple care". I need help getting pass this installation so I can start using My macbook pro. Can someone help me?

    Have you downloaded the Mountain Lion installer from the App Store? It is a stand alone application.

  • While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?

    While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?
    Originally I was running Mountain Lion as an UPgrade from Lion. I created a backup in Time Machine, performed a clean install of Mountain Lion, then I proceeded to use Time Machine to restore the back up.
    When thinking about the essence of a back up restore, it occurrs to me that for all I know, I may have just wated my time IF Time Machine also restores all the old unneeded files that remain from Lion after an upgrade.
    Since the backup was made while running Mountain Lion as an upgrade from Lion, did restoring this backup defeat the purpose of a clean install by reinstalling old Lion files?
    If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?

    Hello John!
    Thank you for your response which solved my problem. For other users who may stumble upon this, I'll clear up the confusion and share how I solved the problem with your help; When looking for answers to my computer problems, finding unresolved questions where person B offers a solution and person A never comes back and says "That worked, thank you.", it demonstrates a "k-thnx-bye" user mentality that leaves others with the same problem lost. Without further ado:
    It is not clear what you did because the meaning of "clean install" is vague. You can erase a volume and install an OS which leaves none of its previous content intact,
    This is what I did: I erased the volume leaving no previous content intact, while then installing OS X Mountain Lion.
    or you can upgrade an existing OS (or reinstall the same one) which does not alter your user - installed files.
    An upgrade to Mountain Lion from Lion is what I started with initially before erasing anything. This was undesirable. Since this can cause Macs to run slower (especially whereas I'm using a mid-2011 Mac Mini), my goal was to go from operating within an upgrade to Mountain Lion, to operating within an installation of Montain Lion that was not preceded by any other oprating system.
    Hence a "clean install of Mountain Lion while continuing with old apps and files" is confusing.
    Well put and understood. What I should have said was:
    1.Erase the volume
    2.Install Mountain Lion clean
    3.Confirm that Mountain Lion is functioning properly
    4.Proceed to use either Time Machine or Migration Assistant to Import/Migrate/Copy over only two things; My old apps (That had been stored originally in the designated Applications folder) and all files and folders originally stored in the home folder under users.
    If you restore from a Time Machine backup then all modifications that occurred subsequent to that backup become erased. It renders moot any OS X upgrade performed subsequent to that backup.
    That makes sense and is just as I later suspected.
    If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?
    Yes.
    This is what I did and everything works perfectly. Thank you so much once again!

  • Mountain lion install crashes-corrupted download

    Twice now, after lengthy downloads to my 27" IMac running 10.6.8. the mountain lion install crashed in the early stages with the same error message that the download is corrupted. please delete the install package from the application folder and repeat the download. After the second try, I decided to try downloading Lion which I purchased early this year but never downloaded.
    Any suggestions?

    The installation could not be completed because errors were found on your drive. Boot up again while holding down the option key and the select Recovery partition. From there, open Disk Utility and first verify and then, if needed, repair the disk "Macintosh HD". If your drive is 'fixable' this will repair any errors.

  • 2008 iMac won't turn on after Mountain Lion installation

    I have a 2008 iMac with 6GB of RAM that was running on OS X 10.6.8 perfectly. Tonight I upgraded it to Mountain Lion. After the installation, my machine was running slower and a little choppy, especially when first opening programs, even though it meets all the requirements for Mountain Lion. After about an hour or two of running like this, I was standing away from the computer for a minute when I saw a flash come from the monitor. I went to it and the screen was black. I thought maybe it had went to sleep, but nope! It was completely off and would not turn back on. No lights or sounds come on at all. There was no power outage or anything, and all other devices plugged into the same surge protector were working fine. I tried plugging it into another outlet and still had no luck.
    Any insight onto what caused this? Is it most likely a power supply failure, and could this have been caused by the Mountain Lion installation? Considering I've had this computer for almost 5 years and this has never happened before, it seems obvious that this contributed somehow.
    Any advice would be appreciated. I'm going to try to take it to an Apple store soon, but the earliest appointment is a few days away.
    Thank you!

    Welcome to Apple Support Communities
    It's quite possible that the power supply failed. The failure is difficult to be related with OS X Mountain Lion, so I would discard that. In some cases, it's normal that you experience slowness after installing a new OS X version because Spotlight indexes the hard drive.
    The best you can do is to take it to an Apple Store or reseller so you can get your Mac diagnosed. Now we can't do anything else apart from thinking that is a power supply issue

  • HT1338 Mountain Lion installation was interrupted - can't restart the download.

    My Mountain Lion installation was interrupted.  Now, when I try to download, it won't do it.  After clicking "Download" it pauses for a moment, and then nothing happens. 
    Any suggestions?  Thanks!

  • How to copy and replace new Mountain Lion hard drive with old Snow Leopard drive?

    So far I have not found an answer to my question, so I am hoping that this is feasible.
    A while ago I purchased a used 2010 Macbook Pro running Snow Leopard that did not have the installer disc. A week ago the hardware died on me, so I replaced it with a new 2012 Macbook Pro running Mountain Lion.
    The problem is that I purchased a 1 TB aftermarket HD for my old Macbook Pro and want to replace the current smaller hard drive in my new computer with it. I've already run Time Machine and put all of my data in my new computer so I figured that it would be possible to simply copy that disk image back over to my old drive and replace it. However the computer showed that they weren't compatible. When I tried to put my old hard drive in my new computer there was not a bootable OSX available.
    Since Mountain Lion already came on my new computer I do not have an installer that I can use.
    Is there anyway I can copy the current Mountain Lion information from my new hard drive and basically have a fully functioning, bootable copy on my old hard drive that I can put back into my new computer?
    Thank you.

    Well, if you put the HDD from the old Mac into an external enclosure you can use a tool like Carbon Copy Cloner or SuperDuper! to clone the Mountain Lion installation onto the 1TB drive.  If you go this route, I would suggest you consider using CCC as it does have the option to clone the Repair Partition as well as the boot volume.
    Another route you could take would be to put the 1TB drive into the new MBP, and then boot to the Internet Recover .  From there you can re-partition the drive and install Mountain Lion clean on the 1TB drive.  During the installation process, you will have the option to use the Migration Assistant to migrate your data & apps.  You can use your Time Machine backup for that, or if you have the original drive in an enclosure, you can migrate directly from the external drive.  I have used this latter method myself a few times.

  • Firefox 18 on Mountain Lion frequently hangs with spinning ball for 1 min while a page is loading, or while opening a new tab. No tabs useable

    Firefox 18 on Mountain Lion. Frequently hangs for minutes with spinning ball, usually while a page is loading (status bar says "loading..." "waiting..."), but sometimes just while on the same page. Other tabs and windows are not useable, even though only one tab is waiting. I usually have 2-4 windows open with several tabs each. Behavior is no different in safe mode. This is making the browser unusable.
    In the past this happened and I've reinstalled or created a new clean profile, but it always recurs.

    The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
    Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
    To Reset Firefox do the following:
    #Go to Firefox > Help > Troubleshooting Information.
    #Click the "Reset Firefox" button.
    #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
    #Firefox will open with all factory defaults applied.
    Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

  • Can't boot Mountain Lion installer on a machine that already has Mavericks installed

    I have upgraded my Mac mini 2012 to Mavericks, and everything is running quite well.  However, I need to also run Mountain Lion (a piece of hardware I need to use is not Mavericks compatible.)
    I am attempting to install Mountain Lion on a 2nd partition on my Mini's internal hard drive by following the following steps:
    * used Disk Utility to repartition my mini's internal drive, creating a 100 GB partition to install Mountain Lion on
    * used DiskMakerX to create a Mountain Lion bootable USB key
    * rebooted machine while holding down Option
    At this point the boot menu appears and I see icons for both my Mavericks partition, as well as the Mountain Lion installer USB key.  However when I select the USB key and try to boot from it, it does not boot; instead I get a gray screen with the universal "no" symbol (circle with a slash through it) on it.
    I tested the USB key on another Mac and it booted fine, so there is nothing wrong with the USB key I made.  So it would seem that the Mountain Lion installer will refuse to run on a computer if it has a newer OS on it, even if the computer has a free partition (or drive) to install on to.
    Is there any way around this restriction?

    Hi,
    to calm your nerves: on my computer I have CS3 and CS4, and I work with both versions, but of course, I never use them at the same time. First, I had CS3, CS4 I installed later.
    All the keyboard short cuts, like yours work free from defects.

  • I replaced my hard drive and am installing the OS 10.5.6 that i got from Apple. It is stuck with 7 minutes remaining. Help! this is the first time I've ever done this.

    I just replaced my hard drive in my 13" Macbook. I got the OS install disk from Apple but it's stuck with 7 minutes remaining. What do I do now? I let it check the disk before the install.

    Did you properly prep your new drive first?
    Drive Preparation
    1.  Open Disk Utility in your Utilities folder.  If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
    When formatting has completed quit DU and return to the installer.  Complete the OS X installation.
    I think you should shutdown the installer then erase the drive per the above and start again.

  • My Mountain Lion mac crashes after resuming from sleep

    Hello
    My Mountain Lion mac crashes after resuming from sleep every time I use it
    It happens every time the mac resumes from sleep and it started like a week ago
    I remember installing the new updates for flash? and xquartz and nothing else.
    I have also had microsoft word installed on my mac for about 1 weeks before this problem started so might be related to that
    Please share with me any tips on how to fix this because I am really annoyed of losing stuff after each time my mac resumes from sleep

    I have an iMac bought may -11, and it worked fine with Snow Leopard.
    About a week ago I bought and installed Mountain Lion 10.8.2. Everything went fine, and all software worked ok. iPhoto had some problems, but after installing update the system prompted to do, it has worked ok.
    The propblem occurs now and then, when computer is waked up from sleep. The Desktop occurs, but no software starts, not even System Tools untlil rebooting the computer. Of course, I can not reboot the computer from "Apple menu", but holding the power button down.
    This is very embarassing! OsX Mountain Lion has turned out to be a very big disappointment. I installed id because of iCloud (i have a new iPad, too with iOs 6 installed).
    Can anyone help me? Is there any other way to solve the problem than re-installing good old Snow Leopard?
    I would not like to do that, I bought Mac because I was bored in re-installing and recovering!
    Thank you

  • Mountain Lion install crash on Mac Pro

    Hi,
    Just started the install on my Early 2008 Mac Pro and it's completely crashed the system. The app downloaded fine and ran OK in 10.7 doing the setup and then tried to reboot. As soon as it rebooted I get a Kernel Panic and the 'Please Power Off your System'.
    I've managed to get into Recovery Mode and am going to restore from Time Machine and try again but has anyone else had this?
    There were no warnings or errors before the kernel panic at all.......
    Thanks,

    This worked for me....
    Restart
    During restart, hold Ctrl + Command + P + R to reset the PRAM
    After this, the computer will flash and reboot again and should boot into the Mountain Lion Installer.
    Good luck.
