What do I do if I have QuickTime installed, but nothing plays?

• Mac OS X

Check QuickTime's settings and make sure it is configured to play MIDI files in your browser.

1. Go to your Apple Menu > System Preferences.
2. Click the QuickTime icon under Internet & Network.
3. Under the Advanced tab, click the MIME Settings... button. The other options on this page should not affect how Wolfram|Alpha uses QuickTime.
4. Expand "Audio - Audio only file formats" and check the "MIDI" option. The other MIME types on this page can be ignored.
5. Click OK.
6. Close the QuickTime preferences window.
7. Restart your browser.
