succhan Level 1 Level 1

I have a site that relies on midi files being played in the browser. Right up until before I upgraded to Mountain Lion I was able to play files with the .mid extension, now they just download instead or if embedded give me the 'missing plugin' message.


I have checked my installed plugins and I have quicktime 7.7.1 which doesn't list .mid as a supported extension anymore.


I can play .mid files through the QT 7 player which lists itself as Version 7.6.6 (1709) but under this is Quicktime 7.7.1 (2599).


So I don't know if the player is using something other than 7.7.1 or not. If it was just stock standard 7.7.1 then why has my .mid files stopped being played in the browser?


Is .mid support really being dropped if so does anyone know of a plugin to get back midi playback?

    I have checked a Lion system at work, it also has the quicktime 7.7.1 plugin but it has the following line






    My mountain lion install is missing that line. Is there a way to add it back perhaps?

    I am having the same problem. Apple needs to fix this soon.

    I have tried a few ideas to no avail. I went back to a Snow Leopard version of the Quicktime Plugin.plugin that I had on a backup which was version 7.6.6 and also to the Lion version which also is 7.7.1 and still they didn't recognise midi as an acceptable format for playing in the browser. I tried adding in the midi dict to the quicktime plugin preference plist and that didn't work.


    It almost doesn't seem like it is the plugin but something in between. In Lion it worked and now it doesn't.


    It's rather frustrating. Hopefully something turns up.

    As a classical musician, this really *****. Midi is a very important tool to our community, and by far the best format to share, listen and practise music with. Especially for choir, where you can play with the levels of the different voices and so on. Almost all sites working with classical music uses midi, so this is a really big loss for us. A lot of the time, the midi file is embedded into the webpage, so you don't have the option to download it and use another player. We NEED midi support in our browsers!

    Fully agreed, Midi file is a very important format, small size, and high quality music. Appreciate someone has the solution to play embedded midi file in Safari 6.0 / OSX 10.8 can share with us the solution.


    Many thanks

    Well - here from Denmark.

    Vi also need midi in our browsers.

    A simple yes or no to the question - Will it ever come back to Mac?

    Other vise we are going back to PCs in the future.

    WOW - after an update on Mountain Lion, and a download of a new Java update from Oracle - ITS WORKING again !?????

  • janedoessis Level 1 Level 1

    Same here! Apparently, crying like a baby works!!!

    I'm running LIon 10.8.2 and I downloaded the latest Java, restarted and I still can play midi's within a browser - just exactly how did you get it working?

  • janedoessis Level 1 Level 1

    I just updated java while my browsers were closed and it worked right after. No restart or nothing.

  • Will James Level 1 Level 1

    I meant "I still can't play midi's" - so how did you do it?

  • janedoessis Level 1 Level 1

    I got that. I did it exactly as I just posted. Updated java while all browsers were closed, opened firefox, went to a site with midi and music came out of the speakers. I don't know how to be more clear about it. English is not my first language.

    Was it Java 7 update 09? If not where did you get it?

  • Will James Level 1 Level 1

    So if you go to Firefox Preferences, Applications and find 'Midi file' - what does it say is the Action?


    Mine says always ask - if I select Quicktime 7 it just downloads then plays - but not within Firefox which is what I want
