Trouble upgrading Mountain Lion

I am trying to upgrade from Lion 10.7.5 to newest but I can't get past selecting an app. when the dialog comes up requesting it.  I see no "app" for the OS to select.

You go to the app store and, on the first page, take a look at the right column - ML is right there:
Click on it, pay for it, and you can download it. You don't need an app - it's an OS.

  • HT1444 can I upgrade Mountain Lion to a Mac 10.5.8

    can I upgrade Mountain Lion to a Mac 10.5.8?

    It depends upon your Mac.  Get more information about your computer. Go to the Apple in the upper left corner of any window, then "About this Mac" and "More Info..."  Copy and paste the information here, but omit the serial number and Hardware UUID (if present).

    Incidentally, you posted this in the 10.3 and earlier forum.  Nobody is going to see it here so it would be good if you selected the correct forum next time you ask a question.

    No, I don't know about that kind of software. It isn't Pages anyway. You need somekind of database.

  • How do I (safely) upgrade Mountain Lion to Mavericks in a triple boot setup?

    When I purchased this refurbished 2011 Mac mini in late April, I wanted to set it up where I could have Mountain Lion, Snow Leopard, and Windows 7 in a triple-boot setup.  Knowing that the hybrid MBR setup limits the hard drive to three partitions, I had to get rid of the recovery partition.  Somehow I was able to make or keep both a .dmg file of the recovery partition and InstallESD.dmg and to clone these to a USB flash drive.  I eliminated the recovery partition, shrunk the Mountain Lion partition, added the Boot Camp partition, and made room for the Snow Leopard partition by further shrinking the Mountain Lion partition.  This setup has been working well for me so far.
    The discussions I'm seeing about people having trouble with the Mavericks installer wanting to create a recovery partition make me nervous.  I don't have an immediate need to upgrade to Mavericks (I use Windows 7 and Snow Leopard more than Mountain Lion), but I would like my third OS to be the most up-to-date version available, especially since Mavericks is free.  I'll be making extensive backups of all three partitions on a larger external hard disk I'm putting together tomorrow, so I'll be able to restore everything if I mess something up, but I'd rather go into the process with a fair amount of confidence that it's likely to work without too much tinkering.
    Any hints?

    The 2010 Mac mini came with Core 2 Duo processors; the 2011 Mac mini had options of Core i5 and Core i7 processors.  My Mac mini is booted into Windows 7 at the moment; the Computer window shows that I have an Intel Core i5-2520M processor running at 2.50 GHz.  This is the model that came with the discrete AMD graphics processor.  The 2011 Mac mini and 10.7 Lion were introduced at the same event; it is highly likely that later versions of 10.6 Snow Leopard included drivers for the new Mac mini in the event that Lion wasn't ready in time.  (The similarities of the 2011 Mac mini to MacBook Pro models released before Lion may also be a factor in Snow Leopard running successfully on the Mac mini.)
    I expected to have to go through extra steps to get Snow Leopard running on my Mac mini, but as long as I installed it and updated it to the latest version by using my MacBook to access the Mac mini's hard disk in Target Disk Mode, it ran just fine.  In fact, one of the first things I did with the Mac mini was the opposite:  I booted the MacBook in Target Disk Mode to see if the Mac mini could boot from the 10.6.8 installation on my MacBook's hard disk, and it worked fine.  I'm sure there are people who have had difficulties installing Snow Leopard on a 2011 Mac mini (with or without a separate Mac that officially supports Snow Leopard), but I guess I lucked out.
    The main PowerPC application that I like to run every now and then is Spaceward Ho!, a strategy game that harkens back to the days of the classic Mac OS (I've been using Macs for twenty years, back to the days of the 68040 processor).  The developer of Spaceward Ho! for the iPad has tweeted that it may release an updated version for Intel Macs, but I don't know that it will maintain the "feel" of the classic version.
    I recently decided to try the iDVD '06 that came with my MacBook on my Mac mini, and while it's not a PowerPC application, it won't run on Mavericks, so I have to keep Snow Leopard for that purpose.  Mainly it's just been a matter of preference:  Snow Leopard just feels more nimble than the more recent releases, and it gives me better control over when I save my files (or copies of them).
    Also a matter of preference:  if I'm running a Windows application, I want to be in Windows.  If I'm running a Mac application, I want to be in OS X.  I also want all of my resources devoted to the OS I'm running at the current time, not divided between both.  I may try virtualization again somewhere down the line, but right now I'm happy enough with Boot Camp.

  • After upgrading mountain lion my mail is crashing during opening

    My imac 2009 has been upgrading 3 days ago to OSX 10.8.3. And since when I select Mail the window is openning and immediadtly shut down.
    I tried to re install la version of mountain lion and deled "folder" in Bibliotheue/maildata. But no resuslt.
    Apparently I am not alone with this trouble.
    Thanks to help me

    Write down all account information or take screen shots. You'll need to reenter the information later. Quit Mail. Hold down the option key while using the Finder "Go to Folder" command and type ~/Library/Containers/com.apple.mail. Move the entire container, not just the contents, to the desktop. Open Mail to see if it works. Reset all account information and test. If no change, put the container back. If Mail works properly, delete the container. You may/will lose some emails if you end up deleting the container.

  • Troubles reinstalling Mountain Lion

    I installed a new hard drive in my mac and want to do a fresh install.  I did the firmware upgrade for internet recovery to my mid-2010 macbook pro and am trying to use internet recovery to reinstall mountain lion.  It says that my apple ID has not purchased Lion, which I know for a fact I purchased Lion and Mountain Lion.  I called apple support on the phone and the guy was super unhelpful and told me to go in store.  Soonest genius appoinment is not for a few days and I need my computer ASAP.  I would use the 10.6 disc that came with my computer but it will not boot to that either (by using "c" or "option").
    So two options:
    1) How can I make the 10.6 disc work? (cleaned it, tried to zap the PRAM and reset the SMC)
    2) How can I repurchase Lion/Mountain Lion without a second mac?
    Any help is appreciated.  Thanks

    I have about the same problem: I bought Mountain Lion and when I try to install on my new ssd drive on macbook pro i7 early 2011 it says that I dont have Lion. I have made a bootable USB memorystick with Mountain Lion but when I start the installation from it, I can't see my ssd in the window of hard drive install location. Only the USB drive is visible.
    If I start network installation, I don't have a Mountain Lion option, only Lion. In Lion installer my ssd is visible but I can't complete the installation because of the bug with the Apple ID wich block me. I don't understand why do I have to have Lion if I already bought Mountain Lion.
    The ssd is corectly formated. I even try to make GUI partiton but all in vain.
    Please help us with this problem.
    Thank you

  • Upgrade - Mountain Lion from Snow Leopard

    I have upgraded my iMac to Mountain Lion from Snow Leopard. I have a MacBook Pro running Snow Leopard; do I need to purchase this upgrade again, or will the previous purchase hold good for my Macbook Pro?

    On your Macbook Pro, assuming it is running Snow Leopard 10.6.8, you can log into the Mac App Store with the EXACT same Apple ID that you previously used to purchase Mountain Lion for the iMac.  In the Store go to your Account's "Purchased Items" list and you should see Mountain Lion listed.  Download it from there for Free onto your Macbook Pro.
    Hope this helps

  • Upgrade mountain lion, cant restore back up n iLife apps missing

    i had upgrade my macbook to mountain lion, now i cant restore my back up from my time machine and all my iLife apps and Microsoft 2008 missing. How can I get it back? 

    About ilife if you bought them from the MAS then you can redownload then again,but if no then they are in the DVD's that come with your mac.The first is the operative system but in the second one you can find the bundle applications they are the ilife applications.Just insert it and install them.
    If you loss the dvd's then contact apple and with your machine serial number probably can get a replacement.
    Hope it helps.

  • Trouble installing mountain lion

    I tried upgrading my MacBook pro to mountain lion. After a few minutes I get an error message saying disk needs to be repaired. Can't seem to exit install screen. Only option is to restart. Working perfectly before trying to upgrade os. Any suggestions?

    @Bimmer,
    I knew that Office apps would look bad from the discussions I've seen on the MS forums. However, there is some display res that seems to work for Photoshop - 1680 x 1050?
    Keep me posted!

  • Is anybody have problem after upgrading mountain lion to 10.8.2?

    I have a macbook pro with 16 meg ram
    I have a new problem since I upgrade to mountain lion 10.8.2 :   My computer freeze  and the only way to make it works is to reboot.
    Is someone have this same problem?
    Any information about that?
    Thanks
    Pierre

    I'm a similar issue, but mine freezes up on almost any program and can't really see a constant reason why. I'm going to try the combo updates as sig suggested to see if that helps.

  • HT4854 trouble downloading mountain lion

    I just bought mountain lion at the app store and it says it is downloading, but the progress bar below the icon in my doc remains empty (pure white).  I'm trying to upgrade from 10.6.8 (Snow Leopard).  Any idea why it's not working?

    Relaunch the MAS app, login, select Purchases, and view an useable progress bar. If it's not DLing or paused, then http://www.apple.com/support/mac/app-store/contact.html?form=account

  • Upgrade Mountain Lion

    if I upgrade my SnowLeo to Mountain Lion, do I keep all my settings?

    Depends on how you upgrade. If you do a an Erase and Install then, no. But if merely do a normal upgrade over your existing Snow Leopard system, then, yes you keep all your settings. If this is what you do, then be sure you repair the hard drive and permissions before you upgrade.
    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.

  • Time capsule trouble with mountain lion

    Ever since I moved and had to resetup my network, and then upgraded to Mountain Lion, I have not been able to run backups on my TimeCapsule with Time Machine. It wont recognize any of the backup files on the two drives, and says the disks are too full to add another backup. That's because it's not accessing the existing ones to do an incremental backup. Neither does Aitport Utility accept the TimeCapsule password. Please help!

    If you have a clean install of Mountain Lion it will remove the 5.6 utility.. but this is still better for setups than the new one. .. certainly for Gen4 TC or earlier.
    The setup of the TC manually from v5 utility.
    Make sure you use all short names.. for the TC itself and for wireless.. I recommend different name for 5ghz as well.
    Use WPA2 Personal security and fix wireless channels.. check 11, 6, 1 in that order.
    For 5ghz try around 40 and around 150.. doesn't matter which one.
    Use ethernet if wireless fails..
    You will hate me but older Mac with ML upgrade that went badly.. sorry get some help to clean install. the wireless in the Mac itself is then the issue.
