• Update Your OS X Mountain Lion App to 10.8.3

    Published on 03-19-2013 10:52 AM by
    The original installation media for Mac OS X Snow Leopard was a 10.6 DVD. The DVD was only updated once to version 10.6.3. In order to provide more frequent updates to users, Apple is now slipstreaming the latest version of OS X directly into the download. Upon fresh installation, no updating is necessary!

    If you purchased Mountain Lion from the App Store prior to March 14, 2013, you most likely have 10.8.0, 10.8.1, or 10.8.2. To re-download Mountain Lion and update your App to 10.8.3, simply log into the Mac App Store and click Update. When the download finishes, the app will automatically open. The updated 10.8.3 Install Mac OS X Mountain Lion App can be found in the Applications folder. You can then re-create your UniBeast installation USB.
    If you don't see the Update button, follow this simple procedure.

    1. Delete your existing copy of Install Mac OS X Mountain Lion.app from Applications folder.
    2. Hold down the alt/option key on your keyboard, and click the App Store icon.
    3. With alt/option key held, click on Purchased
    4. With alt/option key held, click on OS X Mountain Lion
    5. With alt/option key held, click on Install

    If neither of the above processes work for you, try creating a new User account. You can delete it later.

    1. Open System Preferences
    2. Click on Accounts
    3. Click Lock Icon
    4. Click (+) to add a new User
    5. Create a new Admin User
    6. Log out, and log into new User
    7. Proceed with steps above.

      Downloaded and it says that the build number is 12D77, but when I have installed the 10.8.3 combo update, it was saying 12D78. How is possible?

      So... this update killed my sound on both my desktop and laptop plus the laptops status battery
      Probook 4530s i5
      The hp installer fixed the laptop, think the kexts just got overwritten.
      Same deal for multibeast with the desktop just reinstalling the audio kext and graphicsenabler=no for my 660 card

      Downloaded and tried to make a new Unibeast install USB stick with it, but Unibeast says it can't find the install Mountain Lion app? Its there in my Launcher?



      Mmmm sneaky it shows and runs from the launcher but is hidden in the applications folder. Open it in launcher, right click on its icon on the dock and select "show in finder". Right click on the file and copy, then paste onto the desktop. Right click again on the dock icon and choose close. Open the application folder and drag it into there from the desktop. Now run Unibeast and it finds it OK.

      After downloading Mountain Lion from the app store using my real Mac, I moved the installer to external storage. But I found that the app store will not download the new installer unless it finds the old installer. Clicking the Download button only displays a message "You have updates for other accounts". After copying "Install OS X Mountain Lion.app" back into Applications, I tried again and it started downloading.

      After the installation everything is perfect, but the CD-DVD player is not recognized. Can anybody tell me why and how can I fix it? Is there some "drivers" to be installed?

      Same thing here, screen just locks up, mouse keeps moving. Been running in -x mode for the last week - update sucks.
