How do I get my Mac to do nothing when I insert a cd? I recently got an older MacBook Pro that has an optical drive. Every time I insert a CD, iTunes will always respond in some way. 

I have already tried changing the setting in iTunes > Preferences > General, but I don't see the option I want. 

How do I get this Mac to absolutely do nothing when I insert a CD?
You can do this in your Mac's system preferences:


Go to Apple > System Preferences > CDs &amp; DVDs
You'll see a menu for When you insert a music CD
Change that menu from "Open iTunes" to "Ignore".


Notes: 


You may also want to check the options for Blank CD and Blank DVD as they also include built-in options to open iTunes. 
The other menus also provide the ability to run a script, so if you got the MacBook from someone and you're using their old account, these may be worth checking as well in case they're launching iTunes or another application.
