    Hello,

    How are you...

    every time i open System Preferences for the first time after a reboot or shutdown I get a message saying:

    "the preference pane you are installing is already installed. Do you want to replace the existing preference pane?" with two options 'Cancel' and 'Replace'

    and it's been really bugging me but when i look it up I find nothing useful

    here are some info that might be relevant/useful to the problem
    1- Macbook Pro mid12
    2- Mac OS X 10.11 El Capitan
    3- I have 3 third-party panes:
    a- Adobe Flash
    b- Java
    c- NTFS for Mac OS X



    thank you very much for your time and any help you might offer

    Perhaps have a look to see if there are any preference panes located in these two locations which don't appear in System Preferences and that you don't want. If so, trash them.

    ~/Library/PreferencePanes

    /Library/PreferencePanes

    Else, remove all three preference panes you have and install them again.

    sorry for responding so late
    thank you so much for your help
    my problem is solved-- at least for now (hopefully forever)
    you deserve a report
    what I found was a duplicate pane existing in both folders
    deleted one of them the restarted the mac
    and the problem is solved

    thank you...
