Here are the steps for getting the MIDI keyboard to work with Chrome.

1.  Make sure the student is an admin and does not have parental controls.  Get their password.

2.  Make sure the Yamaha driver is installed.

3.  In Spotlight search, type Java and Enter.  If the Apple version of Java is not installed, it will pop up and ask you to install the Java 6 runtime.  Do this.

4.  Run the four terminal commands below.

5.  Open Chrome and type about:plugins in the address bar.  Make sure Java is in the list and Always Allow is checked.  Close Chrome.

6.  Plug in and turn on the keyboard!  Open Chrome and go to the music site for the class you are in.  Log in as the student and test the keyboard.

7.  If you can't make it work, write down the student's name and move on to the next one.

These are the four terminal commands.

sudo mkdir -p /Library/Internet\ Plug-Ins/disabled

sudo mv /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin /Library/Internet\ Plug-Ins/disabled

sudo ln -sf /System/Library/Java/Support/Deploy.bundle/Contents/Resources/JavaPlugin2_NPAPI.plugin /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin

sudo ln -sf /System/Library/Frameworks/JavaVM.framework/Commands/javaws /usr/bin/javaws

The class website for the MIDI keyboard:

Music83  (this is the password for all the student accounts in music83)
The other two classes are Music81 and Music82.
