What App is availiable on app store as USB support for mountain lion? There was one 'USBmate'. Is it okay? If not please tell me how to get the USB support. I have downoaded installation of ML but have not installed it because backups have to be on external HDD. Please help me.


MacBook Pro, Mac OS X (10.7.5)

    OS X completely supports USB 1.0/2.0 natively. No app is required.

    This is confusing. I was very worried when I read this on user tips.

    Note: at the point of writing this

    tip, no USB Flash drive is available for Mountain Lion, and it can only be gotten from Apple Mac App Store.

    I wanted ask this as well:

    Is a Time Machine backup enough for upgrading (i.e. from lion to ML)? Will it cover installed software (eg. Microsoft Office)? Or do I have to install them again?

    I don't know to what you are referring. I think you mean a bootable USB flash drive for installing OS X. If so, then know there is no such thing for Mountain Lion. There was for Lion, but it is no longer available. Apple never included any installer disc for computers with Lion or Mountain Lion pre-installed.

     

    Reinstalling Lion or Mountain Lion is done through the Internet Recovery - OS X (Lion/Mountain Lion)- About OS X Recovery.

     

    If you download Lion or Mountain Lion from the App Store you can save the installer application and make a bootable installer from it:

     

    Make Your Own Mountain/Lion Installer

     

    1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion 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:

     

    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your flash 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. 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.
    4. 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.
    5. 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.
    6. Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.

      

    3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.

     

    4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:

     

    1. Double-click on the InstallESD.dmg file to mount it on your Desktop.
    2. Open Disk Utility.
    3. Select the USB flash drive from the left side list.
    4. Click on the Restore tab in the DU main window.
    5. Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
    6. Drag the mounted disc icon from the Desktop into the Source entry field.
    7. Double-check you got it right, then click on the Restore button.

     

    When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.

     

    Note: The term Mountain/Lion used above means Lion or Mountain Lion.

     

    As an alternative to the above you can try using Lion DiskMaker 2.0 that automates the process.

    A Time Machine backup is like any other backup. Visit Visit The XLab FAQs and read the FAQ on backup and restore.

    Thanks a lot about the USB thing. I thought that it does not support even normal USB.

     

    I do not want to reinstall Lion or ML. I have Lion on my macbook. I have downloaded ML installer from app store. Now, I will have to backup my system before installing ML, right? So is a Time Machine backup enough for the purpose i.e. will I get my Apps and Softwares as they were, if I restore the Time Machine backup on ML?

    It would be wise to backup before upgrading. Time Machine backups are fine. You may want to visit
