    Hi - back in Snow Leopard, i was able to set a specific player (whether QT, VLC, DIVX, etc) as my default player for specific movie file types. Now, there does not appear to be this option. I can only set a default for that exact file, not the entire filetype. So now, I have a bunch of .m4v files I use within Quicktime that got changed to VLC, then I downloaded Spotify, and now they are all set to open with Spotify.

    I can't seem to find any way to update a setting to force all .m4v files to open with Quicktime. Does anyone have any tips?

    right click on a file of the type you wish to change, click "get info", towards the bottom change the "open with" to the program you want, then click "change all"

    Directions to change default player to VLC fails

    I click on VLC and it automatically returns it to QuickTime.
    I've tried every variation I can conceive.
    Any hint is welcome, especially if it leads to success.

    Actually, let me sound PANICED!
    QuickTime has already destroyed half a dozen of my valuable MP4 files beyond repair.
    I do not wish to lose any more.

    Not sure if this will work in your case or not, but…

    CTL-click on your file and choose Open With, then choose Other. Choose the application you want to open with then check the Always Open With check box.

    Hope that works for you, though it may be tedious to do that with all the files you want to change.

    Problem still. Unable to change app, or default app.

    I saw that the offered solution was much like those given by others before.
    Thank you for your response, but I had tried those solutions and they failed.

    I have failed to communicate the problem I am experiencing.
    Please let me try again. Here is what I see step by step:

    1. double-click the lecture folder on my desktop
    2. find lecture10.MP4 file
    3. ctrl-click the lecture10.MP4 file, choose "Get Info", release ctrl
    4. Finder Info window appears
    5. click on "Open with" (original controls contents appear)
    QuickTime (control with up/down arrows to the right)
    Use this application to open all documents like this one.
    Change All... (in a grayed out button)​
    6. click on up/down arrows (list appears)
    QuickTime (default) (checked) (2.1.4) (2.1.2)
    App Store...
    7. click on (2.1.4) (either one will do)

    For a few milliseconds I see (2.1.4) appear in place of QuickTime, then
    QuickTime replaces and the selector is back to original controls contents.
    I am unable to change this field in any way I have thought to try.

    I hope this explanation helps clarify what I am asking.

    How do I change the default app for .MP4 files, given that this way fails?
    Is there, maybe, some text file I can modify, or some command-line?
