On connecting device - iTunes or iPhotos must not open Whenever I connect my iPhone/iPad/iPod to MacMini, It automatically launches iTunes &amp; start syncing every time. I am a developer &amp; I frequently need to connect/disconnect different devices. So, whenever I connect device, I force quit iPhone &amp; iTunes. 

Can I eliminate the initial launch of iTunes and iPhoto when iOS devices connect over USB?
You just have to change the prefs of those 2 apps. For instance, iPhoto you have to choose "No application" in the pop-up menu show hereunder :



And you adjust the settings of iTunes the same way : just check the checkbox "Prevent ...".
