Long ago I upgraded to Mountain Lion but now the App store says there is an update, Mountain Lion 10.8.3 and insists I need to install it even though I have and About This Mac agrees that the system is running 10.8.3.


How do I convince the App store that I'm already there?  It keeps popping up the ML installer, annoying to say the least.

iMac, OS X Mountain Lion (10.8.3)

    Try right-clicking on it and select Hide.


    However, I'd let it run once to make sure there isn't something wrong with my current installation.

    It won't let me right-click.  The status in the Store is 'downloaded' and is greyed out.


    But, it's trying to run the root installer like I'm doing an ML install from scratch.  I really don't think I want that since I'm already at 10.8.3.

    Do you have any external drives or internal partitions that have ML inlstalled which have NOT been updated and causing the App Store to say THOSE need to be updated?

    No, just the Internal iMac drive.  I have a USB drive for Time Machine backups and an Firewire 800 drive for general storage, neither one has an OS on it.

    As stated, right-clicking on the update does not work, no response, above is how it is showing up in App Store.  And periodically the ML installer will launch prompting me to install the full OS.

    I have no idea.

    That can happen if you have a copy of an ML installer for earlier version - 'Install OS X Mountain Lion' , also if



    is giving info to software update/app store which makes it seem that an update is needed.


    If you've no copy of the Installer, see what that plist contains... Textedit can open them, usually; or Quicklook will show you what's inside.


    Here, for 10.8.3, it contains:


    <?xml version="1.0" encoding="UTF-8"?>


    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

    <plist version="1.0">





              <string>1983-2013 Apple Inc.</string>


              <string>Mac OS X</string>

    Did you try using the menu command 'Ignore' as shown in the first link?

    Post a picture of the prompt you're talking about.  Also interested in seeing a pic of the About this mac window, from under the apple menu.


    It sounds like it's just downloaded the update and wants you to restart to apply it.  If you click the Apple >> Restart, does the window that comes up asks if you want to restart and install updates or restart without installing them?


    If so, just restart and install them...
