I've tried 3 times to upgrade my operating system. Each time the upgrade is downloaded, but when it starts to install the upgrades, it stops and says the upgrades were not installed because an error occurred. No mention of what the error was.

My computer is a MacBoor Air running OSX 10.74.

    Hi ..

     

     

    If you are trying to upgrade to Mavericks, make sure your Mac meets the requirements >  OS X Mavericks: System Requirements

     

     

    And make sure there's enough free storage space. Mavericks requires about 8GB's.

     

    Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage

     

    Make sure there's at least 15% free disk space.


     

    If it's not a storage space issue ...

     

     

    • Apps such as Little Snitch, Growl, MacKeeper, and anti virus software can prevent apps from downloading including OS X upgrades

     

    • Disable anti virus software if installed

     

    • Check the firewall in System Preferences > Security & Privacy > Firewall > Firewall Options

     

    • Make sure Gatekeeper is enabled

     

    Open System Preferences > Security & Privacy then select the General tab.

     

    Make sure either Mac App Store or Mac App Store and identified developers is selected.

     

    If that area is grayed out, click the padlock icon to proceed.
