OSX mountain lion installation

Ive downloaded OSX mountain lion but when I try to install it on my hard drive it tells me "this disc is used for Timed Backup" and doesn't let me select it. ?

Remove the directory Backups.backupdb from the target drive. 
Before doing this make sure you have your Time Machine backups on another drive.

  • OSX Mountain Lion installation without internet access/media installation

    Hi. I had a problem with my hard disc and can't access my OSX anymore. I had to replace it, and now I want to install the system again, but to install trough internet it's impossible, almost 30 days to download, and I haven't any media with the system. How can I download the system to a media (DVD or usb disc) using Windows system (it's the only system that I have in hands now) and create a boot media to install again in my Mac?
    Thanks a lot.

    You can't log into the App Store from a PC. Why are you not able to download from your Mac? Your model should be able to do Internet Recovery:
    Install Mavericks, Lion/Mountain Lion Using Internet Recovery
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    1. Select Disk Utility from the main menu and click on the Continue button.
    2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet
                if possible because it is three times faster than wireless.
    This should restore the version of OS X originally pre-installed on the computer.

  • Download lastest version on Install OSX Mountain Lion

    I tried to re-download the latest version of OSX Mountain Lion installer from the App Store, but it says it cannot, because Mountain Lion is not compatible with my computer.
    I have a new iMac 27" that is running Mountain Lion on a Fusion Drive.  Why won't the App Store let me download the installer? 

    The Late 2012 iMac has got a special OS X version that it's not available in the App Store, and that's why you get a message telling you that your Mac isn't compatible, but you're using Mountain Lion.
    Until Apple releases OS X 10.8.3, you can only reinstall OS X Mountain Lion starting into Recovery, pressing Command and R keys while your Mac is starting, so you can't create a USB drive. When Apple releases OS X 10.8.3, download Mountain Lion in the App Store and you will be able to create a USB drive with OS X Mountain Lion with Lion Diskmaker

  • My friend have new Macbook Air with OSX Mavericks and I have Macbook Pro with OSX Mountain Lion, Can I create a bootable maverick in pendrive from macbook air and perform a clean installation/update on my macbook pro with osx mountain lion?

    I have late 2012 edition Macbook Pro, I have a internet connection with does not run smoothly It gets disconnected and reconnects Thus I failed everytime when I update my OSX Mountain Lion to Mavericks in App Store. My friend just bought 2013 end Macbook Air whicch have OSX Mavericks pre installed.
    I was hoping if I can create a OS X version in pendrive from his laptop and use that to install and thuss also update OS on my Mountain Lion.
    Kindly explain me in detail how to perform this.
    I have already taken back up of all files and I am ready to total clean my laptop.
    And I want to update to Maverick so I can thus further update to upcoming OS X Yosemite.

    The Mavericks on the Air is probably machine specific since it came pre-installed, so it wouldn't work on your computer. See if your friend will let you access the App Store, where you can sign in using your Apple ID and download the installer. You can use this free program to copy the installer and update your computer.

  • Just upgraded my MacBookPro to OSX Mountain Lion. Now unable to reinstall Capt.Installer driver for my Canon LBP3010 printer. Same installer was used in previous OS

    Just upgraded my MacBookPro to OSX Mountain Lion. Now unable to reinstall Capt.Installer driver for my Canon LBP3010 printer. Same Capt.Installer was used in previous OS.
    Got message that the software was not obtained from Apple or trusted source.
    Anyone can help solve this issue, do not wish to purcahse new printer, and Apple does not appear to be friendly to me

    Apple is still friendly, only became more protective - for your very best. Right-click on the installer, then "Open", and then you get a window offering you the option to run it. That's a ML feature. Again, for your protection.
    Independently, and as not only with Apple, a new OS X is sometimes different, and ML is that bit "pickier" with fully compatible software. So, even if your driver ran under Lion, it can be that it won't under ML. In that case please check Canon's website if they have a newer ML-compatible version, If not, also go and blame Canon. It's their responsibility to provide up-to-date drivers, not Apple's.
    Good luck.

  • Why does my Macbook Pro keep shutting down during installation of OSX Mountain Lion?

    Why does my Macbook Pro keep shutting down during installation of OSX Mountain Lion?

    Hmm, good luck then!
    I'm pretty much exactly on the opposite side of the planet, but I've been to Vermont and remember its rural beauty well. However, I can't imagine you having the only Internet connection within a reasonable radius (where "neighbors" hanging off the same ISP don't count). Uh, that note only if your wired connection to the router produces no good result, either...

  • HT1338 I just installed OSX snow leapord and just want to be able to use icloud.  I up--graded my old macbook to 2 gigs and still can't get it to download icloud .  would go to osx mountain lion but can't do that either.  What do I have to do???

    I want to use icloud to sync w/my new apple tv.  bought osx snow leopard and installed it plus upgraded to 2 gigs memory for my
    old (2007) macbook.  still won't work. I need to get to at least osx 10.7.4 or to osx mountain lion.  Tried everything and can't get there.
    I'm not a computer whiz...quite a novice.  so, if you can help; please speak in layman language....ha   Thanks

    iCloud requires 10.7.2 or later.
    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.
    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.

  • When installing mountain lion on my computer, why does it say "OSX Mountain Lion couldn't be installed, because the disk \ is damaged and can't be repaired."

    I'm unable install mountain lion on my computer. Every time it says "OSX Mountain Lion couldn't be installed, because the disk \ is damaged and can't be repaired. Click restart to restart your computer and try installing again." So I press the only button listed as an option, it restarts, and the same screen comes up again. I can't make mountain lion go away...I've tried many times. What is wrong with my computer? It's stuck like this and I can't even get snow leopard back on there if I wanted to because I can't get away from the same screen. Please help : (

    Insert your OS installer disk in the optical drive. Power the Mac down by holding down the power button. Then power back up and hold down the 'c' key so the MBP boots to the installer disk. From Disk Utility you should do a Repair Disk. If DU successfully repairs the disk quit the installer and reboot your Mac. You should update to 10.6.8 prior to upgrading to ML.
    http://support.apple.com/kb/DL1399
    Then do your ML upgrade install.

  • Reinstalling OSX mountain lion

    My computer is acting strangely and stops all the time to work - I can hear lots of little hard drive sounds and it is very slow until it is done (usually about 10 minutes), and my Adobe CS products are crashing and creating corrupt files that keep stopping.
    I tried to reinstall the system today - I couldn't use the installer that came with the computer because I have installed Mountain Lion since.
    I tried installing from the 'Install OSX Mountain Lion.app" file, and it went through the motions and said it was installing, but now it appears to be exactly the same - normally I would get the welcome screen and have to configure things.  It did not give me an option to do a clean install.
    How can I do a new installation to get rid of the existing problems on this computer? It is only a year old (iMac i7) and has 8 gb of RAM so it shouldn't be so slow. My laptop is the same and is much faster.
    thanks for any help.

    I couldn't use the installer that came with the computer because I have installed Mountain Lion since.
    FWIW (and future reference), you should be able to install the original system (if it was Lion):
    If you use internet recovery (Command + Option + R), then the original OS version will be reinstalled after you wipe the drive.
    If you use recovery (Command + R) the current OS version will be reinstalled.
    If the originally installed OS version same with install disks (Snow Leopard or earlier), you can boot from that disk; however, in order to revert, you will need to wipe the drive first.
    And, since you want to get rid of "existing problems", starting over with a clean install is best. You do not know if your problems are only caused by the OS or possibly some incompatibility of third party software which would not be fixed if you simply reinstall the OS over the top of what you have.

  • Osx mountain lion not downloading

    My download of osx mountain lion gets to 142mb then stops! I've tried deleting the purchase and redownloading still the same thing,
    does anyone have an answer for this annoying issue!

    Hello, how much free space on your Hard Drive?
    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)

  • OSX Mountain Lion - piece of junk

    OSX Mountain Lion is a pice of junk!
    (and this is coming from a die-hard Apple enthusiast)
    the system crashes, the promised quicker performance is at at the cost of stability of the system,
    shame on you Apple!
    I cannot even write a review using the reguler channels (from launchpad) because it crashes
    (and believe me, restarted the system several times)
    Lost data during systems forced restarts, this is costing me hours of work!
    (automatic data restoration does not work, dociments do NOT get saved)
    what a joke!
    Give me back my Snow Leapoard,
    wait, you can't!

    As Thomas says, may be an error during the installation, my advice is to re-install wat mountain lion, then download it from macc app store, create a key or a DVD boot:Want to make a Mountain Lion USB stick or SD Card Installer?- 9to5Mac
    save the things you need, reformat and re-install.
    also tries to use utility disk to verify and repair the disk and / errors (prior to the procedure that I outlined above.
    or re-install snow leopard (next you have reformat ) and install mountain lion
    from this address you can see the app compatible with mountain lion

  • How to download but not install OSX Mountain Lion on Mavericks

    Hi all
    I would like to download but not install OSX Mountain Lion on my MBP which is currently running OSX Mavericks.
    This however seems impossible. I think OSX Mavericks were already installed on my MBP and therefore it seems "impossible" to download it.
    Now, why would I to do this? The answer is quite reasonable, due to certain demands related to an application portfolio I need Mountain Lion, because the portfolio is not upgraded to run on Mavericks. And, it is more reasonable to downgrade a version of OSX, rather waiting for the portfolio upgrade which can take years.
    Yes, I need to downgrade my secondary MBP which also came with preinstalled Mavericks. This can be done, if I only could download but not install Moutain Lion.
    It should be easy enough; download Mountain Lion, make an installer and make a bootable thumb usb stick. Then erase Mavericks and install Mountain Lion.
    I have previously bought Mountain Lion so it is accessible to me in the App Store, but whenever I try to hit the Download button, I get a message saying this can't be done, since I am running Mavericks.
    This bugs me, it should be obvious users needs the flexibility to swap whatever OSX version they need. It is still software.
    So, how can I download but not install Mountain Lion on my newer MBP that came with preinstalled Mavericks?
    I would like to see answers like:
    "In order to get this to work, you first have to disable the locking mechanism in [...] " instead of "No, this is impossible to do"
    Regards

    Thanks for your reply Eric
    Can't help wondering thought, people are ok with this?
    Basically Apple are saying: "Do not attempt to install an older version of OSX which came preinstalled. If so, expect multiple failures." Really?! Has it always been so? For me it's not like I'm going to install Snow Leopard on my Late 2013 Retina MBP, but I would expect some form of backward compatibility between the previous version and it successor. Apparently this is not possible, and how is this even acceptable? 
    Personally, I am not going to downgrade, as if I had a choice, but I would and I expected however, the possibility to at least download the previous OSX version. What do you do if you have bought several applications, not necessarily online from App Store and buy yourself a new Mac with preinstalled Mavericks and after installing your "old" applications they fail to work properly? What do you do since downgrading apparently is not an option. So... again, what do you do? 
    If you don't have friends with an older Mac, you could be facing serious problems. And I'm not talking about gaming, but serious business. 
    I find this quite disturbing actually, and please tell me it's not so. There gotta be a way to do this?
    I simply want to download the OS but I expect some registry values (like windows' registry) keeps preventing this.
    It should be possible to simply download and not download and install in one operation, shouldn't it?
    Regards

  • Download of update to OSX Mountain Lion

    I was updating to OSX Mountain Lion, used my computer for something else and the download got interrupted.
    How do I resume the download?

    That is a point many users miss...even Apple has limited bandwidth when it comes time to release a major operating system and millions of users want to download at the same time...during the first two weeks one should expect delays and long, long download times.
    It is getting to the point that suggesting downloading during "off hours" isn't even good advice...world-wide there is no such thing as an off hours time segment
    I have a very fast f9ber optic carrier and download took around thirty minutes...another good reason to tell people to make a copy of the installer before doing the installation so you do not need to download again.
