If the wrong app opens when you insert a CD or DVD into Mac
If the wrong app opens when you insert a CD or DVD, you may need to change your settings in CDs & DVDs preferences or in the preferences of the app that’s opening. Also, the CD or DVD may not be the type you think it is.
You may need to choose what happens when you insert a disc. Choose Apple menu > System Preferences, click CDs & DVDs, then choose the actions you want from the pop-up menus.
Note: If you don’t have an optical drive built into or attached to your Mac, CDs & DVDs preferences aren’t available.
The disc you’re inserting may not be the type of disc you thought it was. For example, an app may not consider a CD that contains MP3 files to be an audio CD if you created the disc in the Finder.
