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?

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.

  • How can I buy Mountain Lion from an unsupported laptop? I want to install it on a Mac Pro but it doesn't have an OS to open App Store

    I have a MacBook Classic that is unsupported and my Mac Pro is supported but I can't open App Store from it because there's no OS and I can't purchase from my classic because it's unsupported. Halp

    Buy Snow Leopard for your Mac Pro, update it to 10.6.8, purchase and download Mountain Lion. There is no other solution.

  • How can I get beyond the installation error point 1336 that occurs, after I installed Firefox 3.6.16, when I try to install the latest version update to Adobe Reader?

    After installing Firefox 3.6.16, I received an Adobe Reader update alert that there was an update available. I downloaded the update and then began the installation. During the installation, I received the following alert: "Error 1336. There was an error creating a temporary file that is needed to complete this installation. Folder: C:\Program Files \Mozilla Firefox\plugins\. System error code: 5." This prevents me from installing the update -- at every attempt! Is there a user friendly solution?

    I am happy to see another person is having this jerky scroll situation with the latest update to Firefox on October 27. I did check my I.E browser and '''THAT BROWSER''' still does the nice smooth scroll....let's get 'er fixed Mozilla! I know you can!

  • How can I set up an external harddrive with time machine that already has data on it without losing the data?

    I have an external hard drive that I use to hold photos and other files on that no longer fit on my macbook. I also use the external hard drive for back ups set up with time machine. I don't believe I ever did anything to partition it, I've just always had separate folders (Photos, Music, etc) with one being called "Back Ups" (or Backups.backupdb) that my time machine back ups would automatically go into. Recently, I made the switch from my HDD in my macbook to a new SSD of the same size. I used the back ups on the external hard drive to restore all my content, which all worked out fine. My problem now is in using my external hard drive. When I plug it in, it no longer seems to be working with time machine. Also, I was organizing some files within the external hard drive, and when I dragged one into a folder, it took a while to load. Before, it was instantaneous moving a file already on the external hard drive to another location within it. Can anyone help me in getting the external hard drive to work with my new SSD? I don't want to delete any of the folders or back ups that are already on it, since that's the only place I have some of those files. Please let me know if you need anymore details. Thanks! (sorry if this is posted in the wrong forum)

    First, she has to be logged in to the same iTunes account as she used on the old computer.
    Second, when she plugs the iPhone in to iTunes, right click on the phone name and select transfer purchases.
    Third, enter one contact and one calendar entry into the new computer's addressbook/calendar.
    After that, she should be fine.

  • Where can I download the Lion installer?

    I purchased Lion when it was released and installed on one machine. I now have a new machine that I want to update to Lion but when I go to the App Store it just tells me that Lion is no longer available in the UK store.
    Where and how can I find the Lion installer download?  I can't put Mountain Lion on becuase the machine is not 64bit.

    The installer is found in the Applications folder once the download is complete. It's gone after its first running.
    Those are facts.
    Right but he can still download it from the Mac App Store.
    Which is what he asked.
    Where and how can I find the Lion installer download?
    Not where is it on my computer.
    Your post leads him to believe it is No Longer available to him in any way. Which is completely WRONG.
    So as I stated before do some research before posting Misinformation.
    Or don't reply to questions you don't know the answer to.
    Thanks again.

  • Can I load Mountain Lion to a second computer [for free] if the original came on a new MacBook?

    I recently purchased a new MacBook Pro which came preloaded with OS X Mountain Lion.  Can I download Mountain Lion to a second computer?

    For a Pre-Installed version, there is no feasible way to do it, even if the license allowed. You can't download the installer. You can only reinstall via Recovery HD or Internet Recovery.
    If you got a copy of Mountain Lion via the Up-to-date program, you can use that as it comes with a Mac App Store license.

  • 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.

  • Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair I need to boot off of another source, like my flash drive.

    Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair, I need to boot off of another source, like my flash drive. I am in Paris and my Snow Leopard DVD is in Texas.

    Mac OS X has a built-in disk diagnostic and repair program called fsck or file system consistency check. Here’s how to verify and repair your startup disk with fsck.  As soon as you hear the startup tone, press and hold Command-S on the keyboard. Keep holding down those keys until you see a black screen with white lettering. This is called “booting into Single User Mode.”  As the Mac boots in this mode, the screen reports each step of the process. The line should end in root#.  Right after the root# prompt, enter the following: /sbin/fsck -fy
    If repairing the disk in single user mode fails, it means one of two things. Either your hard drive itself is failing (a hardware failure), or the directory damage on your hard drive is beyond the capability of the built-in repair procedures in OS X.

  • Can I dual boot Mountain Lion and OSX10.6.8

    Can I dual boot Mountain Lion and OSX 10.6.8. I just upgraded to Mountain Lion and my InDesign CS2 no longer works. If yes, how does one do it.
    Thanks all,

    Yes, as long as your computer shipped with 10.6.8 or earlier. Insert the Mac OS X 10.6 DVD, restart with the C key held down, and install it onto a separate partition or drive; if you use Boot Camp, repartitioning the internal drive may disable it.

  • Can't reinstall mountain lion

    Hi, I just purchase a used macbook And I was trying to delete the previous owner account and info, I deleted de OS X mountain lion and when I try to reinstall it a message shows "This item is not available, try again later"... I have try several options and nothing seems to work. Please Help!

    OK. Here's what you will need:
    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mavericks if your computer meets the requirements.
    When you receive the Snow Leopard DVD you will do the following:
    Clean Install of Snow Leopard
         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
             with your computer.  Insert the disc into the optical drive and restart the computer.
             After the chime press and hold down the  "C" key.  Release the key when you see
             a small spinning gear appear below the dark gray Apple logo.
         2. 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.
             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, click on Options button
             and select GUID, click on OK, then set the format type to MacOS Extended
             (Journaled, if supported), then click on the Apply button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Be sure you configure your initial admin account with the exact same
             username and password that you used on your old drive. After you finish Setup
             Assistant will complete the installation after which you will be running a fresh
             install of OS X.  You can now begin the update process by opening Software
             Update and installing all recommended updates to bring your installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    Now, when this is completed you can download Mavericks from the App Store and install it on the MacBook. However, I suggest you use Snow Leopard for a while first because it will perform faster than Mavericks. Mavericks requires a lot more memory (at least 4 GBs) to run smoothly, and it needs faster graphics than you have in that MacBook. If you decide to go forward to Mavericks, then be sure to make a bootable backup of the Snow Leopard system just in case.
    If you get Mavericks, then I suggest you read this:
    Make Your Own Mavericks, Mountain/Lion Installer
    After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
       2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
    Open Disk Utility in your Utilities folder.
    After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. 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 then click on the OK button. Click on the Partition button and wait until the process has completed.
    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.
    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.
    Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
    Use DiskMaker X to put your installer clone onto the USB flash drive.
    Make your own Mavericks flash drive installer using the Mavericks tool:
    You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
    You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this entire command line after the prompt in the Terminal's window:
         sudo /Applications/Install\ OS\ X\ --volume
         /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ --nointeraction
    Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.
    Wait for the process to complete which will take quite some time.

  • Mountain lion installation query

    I have a MacBook Pro which came with snow leapord. Then I upgraded it to oS X Lion.
    This new installation happened over the existing OS, that was snow leapord. 
    Now with new oS update which is coming today, I'm sure it will be installed on Lion. Which means a lot of junk from snow leapord and Lion will remain in the MacBook which would make it even slower then now.
    My query is, can we just format the Mac disc and install fresh mountain lion? If, yes, how?

    If your machine came with the Snow Leopard install disk, you can just boot to your installation disc, erase your hard drive and reinstall Snow Leopard. Then make sure that you do the combo 10.6.8 update and you'll be ready for ML. Make sure that you have a backup, of course, before erasing your hard drive.
    Honestly, I wouldn't be worried about any 'left over' files from previous operating systems. Those will be erased or overwritten by the new version of OS X. There really won't be any 'junk' files. If you have extensions, etc., that are incompatible with ML, they will be placed in a folder on your root directory.
    If your machine is slow, it's probably due to other problems than the OS. If I were you, I'd just do the ML upgrade and if your machine is still running slowly report back here.
    Good luck,

  • Can I run Mountain lion?

    From what I can see online it's saying I can't run Mountain lion on my iMac however if I go by just the spec's alone it seems I could run it. I'm not sure if I should just go ahead and try to see if it runs or not so I thought I would post the spec's here and see.

    I don't have much in the way of documation for this iMac as it was purchased from a college auction in the summer. However I do know that this college is know for going with higher end models and addding extra stuff to their machines to handle the Adobe Creative Suits better.
    Also the main reason for me wanting to update this iMac is because as I have other apple products and it seems like iCloud will help me keep things in sync better. As a heavy users of iCalendar I would love to have this sync acrros all my devices.
    The devies in question that I want to sync besides the iMac are a MacBookPro5,5, iPhone 4, and a iPad with Retina display
    Also I take it, it's safe to assume my MacBookPro5,5 will run Mountain Lion just fine?
    P.S - When I download Mountain Lion from the app store can I use it on both my machines or is it a single use download?

    Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
    Upgrading to Snow Leopard
    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s iCloud services; fees and
               terms apply.
    Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
         Lion System Requirements
           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
               or Xeon processor
           2. 2GB of memory
           3. OS X v10.6.6 or later (v10.6.8 recommended)
           4. 7GB of available space
           5. Some features require an Apple ID; terms apply.
    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
         OS X Mountain Lion - System Requirements
           Macs that can be upgraded to OS X Mountain Lion
             1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
             3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
             4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
             5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
             6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
             7. Xserve (Early 2009) - Model Identifier 3,1 or later
    To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
         Are my applications compatible?
