  • Can't install OSX Mountain Lion, on the disk selection screen i cant select the Macintosh HD to install OSX giving a message (This disk cannot be used to start up your computer).only have one disk to select and my partition map scheme is GUID partition

    just bough OSX Mountain Lion, my laptop operating with v10.6.8.  Can't install OSX Mountain Lion, on the disk selection screen i cant select the Macintosh HD to install OSX giving a message (This disk cannot be used to start up your computer).only have one disk to select and my partition map scheme is GUID partition table. 24.44gb disk available.

    Verify your computer can run Mountain Lion:
    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.
    Open Disk Utility and verify the drive is partitioned using GUID and formatted Mac OS Extended, Journaled. If it is then do this:
    Repair the Hard Drive and Permissions
    Boot from your Snow Leopard 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. 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Now try installing Mountain Lion.

  • Can't install MAC OS X Lion - Macintosh HD "This disk cannot be used to start up your computer."

    I downloaded OS X Lion this morning and when I went to install it I got a "Screen - Select the disk where you want to install OS X."  -- Had two disk my Macintosh HD and my Time Machine (both are 1TB).  The top and most important is the Macintosh HD (999.86GB - 739.75GB available states "This disk cannot be used to start up your computer".  What do I need to do to install OS X Lion?

    Create a Backup Lion Bootable 10.7  Disk
    Purchaseand download Lion from the Mac App Store on any Lion compatible Macrunning Snow Leopard.
    Right click on “Mac OS X Lion”     installer and choose the option to “Show Package Contents.”
    Inside the Contents folder that     appears you will find a SharedSupport folder and inside the     SharedSupport folder you will find the “InstallESD.dmg.” This is     the Lion boot disc image we have all been waiting for.
    Copy “InstallESD.dmg” to     another folder like the Desktop.
    Launch Disk Utility and click the     burn button.
    Select the copied “InstallESD.dmg” as the image to burn,     insert a standard sized 4.7 GB DVD, and wait for your new Lion Boot     Disc to come out toasty hot.
    With this disc you can boot any Lion compatible Mac, and install10.7 just like you installed previous version of Mac OS X. You caneven use Disk Utility's Restore function to image your Lion boot discimage onto a external drive suitable for performing a clean installon a optical-drive-less MacBook Air, or Mac mini server.
    If your using Mac's in a mission critical type environment or have third party hardware or software you must rely upon working correctly. It's advised to wait until all the bugs, driver updates, third party software updates and other issues are resolved before upgrading. This might take several months. Then if you do so, do one machine at a time and carefully test everything before full deployment.
    It's also highly advised to backup all one's data either manually to a external powered drive in addition to TimeMachine and Hold option bootable Carbon Copy Clones etc.

  • Mountain Lion wont install on macbook. "This disk cannot be used to start up your computer"

    Basically, when I try to install the mountain lion update onto my Snow Leapard OS, I get the above message. Something must be wrong with my hd configuration.
    I think the problem was caused when I tried to install linux on a partition before this and failed miserably time after time; I think the problem was that reFIT wasn't recognizing the proper partitions to boot into. Anyway, I also noticed that even after deleting the defunct linux partitions using Disk Utility, the linux drives still showed up in the reFit startup menu. Did I screw up my HD? Is that what is preventing me from installing Mountain Lion? If so, how can I fix it?
    Thanks.

    Go to System Preferences > Startup Disk and press Macintosh HD. Open > http://support.apple.com/kb/TS3926

  • I just bought and installed mountain lion, and I can't get to sign in to hotmail.Can I get some help please. Thanks.

    I just bought and installed mountain lion, and I can't get to sign in to hotmail after several trials. I need help please. Thanks.

    so its in a forum, which I didn't stumble upon because it wasn't anywhere in the adobe troubleshooting steps for Windows 8 that automatically came up for me when I clicked that I couldn't see the test flash movie on their site. I guess if I spent another half a day googling I might have found it.
    BTW, unchecking Active X filtering in IE10, was NOT the fix. I had to go into the security tab, and change the custom active X setting I listed above. So this link you provided which mentions unchecking Active X filtering was not the fix that worked in my scenario.

  • I bought and downloaded mountain lion, but it's in my downloads...

    ...as needing downloaded? I actually just downloaded and installed the update and am running 10.8.1 and it says so under 'about this mac'. I clicked on download and it said that it was already installed, so I cancelled it, and it started downloading! I paused it and now it's waiting for me to resume... What do I do? thanks in advance for your help...I'm a rookie!

    The App Store is referring to the "Install OS X Mountain Lion" application, not to the OS you're running at the time.
    If you want to re-download the installer, you can.  But you can also just ignore it, or hide it, in the App Store.

  • I just bought OS X Mountain Lion, but it won't install. What do I do?

    I just bought OS X Mountain Lion on my Macbook Air. A friend recommended it to me, so I downloaded it. She also has a MacBook Air, and on her Mac, it popped up a window immediatly saying that the computer would shut down and download at the same time. But on my Mac, nothing happened. It says that it will be delivered from 18-20th of November. That's not the way it should be. So what do I do now?

  • HT4906 I have just downloaded Mountain Lion but my iPhoto app cannot be launched as it says the original app cant be found. It takes me to where is says its located but its not there.  What to do?

    I have just downloaded Mountain Lion but my iPhoto app cannot be launched as it says the original app cant be found. It takes me to where is says its located but its not there.  What to do?

    Reinstall it?
    To re-install iPhoto
    1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
    2a: On 10.5:  Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name.
    2b: On 10.6: Those receipts may be found as follows:  In the Finder use the Go menu and select Go To Folder. In the resulting window type
    /var/db/receipts/
    2c: on 10.7 they're at
    /private/var/db/receipts
    A Finder Window will open at that location and you can remove the iPhoto pkg files.
    3. Re-install.
    If you purchased an iLife Disk, then iPhoto is on it.
    If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only.
    If you purchased it on the App Store or have a Recent Mac you can find it in your Purchases List.

  • I just bought and downloaded an embroidery file but Adobe Reader will not open it.  What can I do?

    I just bought and downloaded an embroidery file but Adobe Reader will not open it. What can I do?

    Is it actually a PDF file or something else.
    You haven't given us enough information to do anything other than throw random guesses your way.
    Version of Reader? File type? Downloaded and saved to your desktop or are you clicking a link?
    Opening in browser or using File>Open in Reader?
    More info is better.

  • I just bought and downloaded an album.  the album/tracks are NOT found in my music listing alongside every other track i have purchased! however, they are found and playable in the recently added playlist. plz help

    i just bought and downloaded an album.  the album/tracks are NOT found in my music library alongside every other track i have purchased! however, they are found and playable in the recently added playlist.  in addition, when using the search queue in the upper right corner, the artist and album is listed when searched for, but when clicked on, nothung happens.  i have downloaded hundreds of tracks with no issue (not a noob), but have no idea what has occurred...plz help

    Have you checked whether the songs are in your iTunes library? If they are, then just drag them to your purchased playlist. If they aren't, try checking for available downloads.
    If none of the previous work, then get in contact directly with iTunes store support to tell them about your problem.

  • I re-booted my macbook pro recently and downloaded mountain lion. Afterwards iPhoto disappeared and I'm having difficulty restoring it. Any suggestions?

    I rebooted my macbook pro recently and downloaded mountain lion. Afterwards iPhoto dissapeared and I canr seem to restore it. Any suggestions?

    Rebooting is the same as restarting. That should not have any effect on what software is installed on your machine unless something is very, very wrong. Do you mean that you erased the hard drive and installed Mountain Lion? If so, you will also need to reinstall iPhoto. What system did your machine originally ship with? If it came with disks, you can reinstall the iLife apps from the Applications disk.

  • Why can't I purchase and download Mountain Lion? I get the following message: The product distribution file could not be verified. It may be damaged or was not signed.

    I have tried to re-install Lion, delete different cach folders, etc., nothing is working - I keep getting the same message:
    We could not complete your purchase
    The product distribution file could not be verified. It may be damaged or was not signed.
    Please can anyone be of kind assistance.
    Thank you!

    I have tried to re-install Lion
    If you are trying to reinstall Lion, you need to use Lion Recovery
    Why can't I purchase and download Mountain Lion? I get the following message:  The product distribution file could not be verified. It may be damaged or was not signed.
    For that issue, quit the App Store if it's open. 
    Open the Finder. From the Finder menu bar top of your screen click Go > Go to Folder
    Type this exactly as you see it here:
    /Library/Preferences/SystemConfiguration
    Click Go
    Move the NetworkInterfaces.plist file from the SystemConfiguration folder to the Trash.
    Relaunch the App Store and try downloading MLion.
    *****   Your post is rather confusing. There's a difference between reinstalling Lion and downloading Mountain Lion.
