iTunes starts playing by itself


I don’t know if you remember, but the last time that you were here, one of the problems was that iTunes would pop up and start playing.  You did something—I wasn’t watching- and the problem did go away for a little while.  It slowly came back, and now it pops up every few minutes even though I am constantly hitting “Quit iTunes”.  I did upgrade to OS X Yosemite, but that did not seem to make any difference.

There are several potential explanations as to why iTunes might start playing randomly. A couple of simple things to check first.

Keyboard key stuck? Try disconnecting the keyboard temporarily to see if the problem goes away.
Inadvertent signal being received from AppleTV remote.

other possibile solution to try:

Right Click on iTunes within the applications to check sharing & permissions. (right click app, then select "get info.") Note that "wheeler" has read&write access. Remove wheeler by using the minus button at the very bottom of that window.
