    Hi,
    Files are not opening with the program I designated to open with.
    For exemple : video files are now opening with Quick time player while I had selected VLC player. It always works for a couple of weeks/months and then one day all files that I open will open with the "default" application.

    And yes, I do know to use "change all" in the Info pane.

    The only application I suspect to mess up is Clean My Mac 2, but I'm not sure and even IF this was the case, I wouldn't know what to do.

    I have a MacBook pro 13 late 2013 - Latest version Mavericks

    This the third or fourth time in 10 months that I have this problem.

    Anyone that could help?

    Guy

    OK, I removed it

    Is it ok that I use Appcleaner to uninstall apps? or is that also not
    necessary?

    I only have My Macbook pro for 11 months and I am still used to clean and clean like I did in crappy Windows 7.

    I just wished I dumped Windows sooner

    Thanks for the info

    Guy

    There is feature of OS X called launch services database where that launch info is stored. There is a Terminal command that can be used to reset that database back to defaults. I suspect what is happening is one of the routines run by Clean my Mac is running that command to reset the launch services database and the result is what you are experiencing.

    It's okay to use an app like that to uninstall applications. It will get rid of the bulk of the installed files but may miss a small settings file/folder or two, but no big deal. If you want to be sure you get every last piece of an installation you will need to track down the files manually and delete them.
