About a week ago, iTunes stopped opening when I connected my iPhone. If I then open iTunes manually, the device will be recognized and will sync. I checked in the system preferences and my Login Items had iTuneshelper checked, but the icon was a blank piece of paper and on the righ margin there was a yellow triangle with an exclamation point in it.
I don't necessarily want iTunes to open when I connect my iPhone, but I would like to be in control of if it does or doesn't.
How do I set this straight?
Ah-hah! My iTunesHelper was "unknown"!
With a bit more researching, I found this:
Goto System Preferences:Accounts:Login Items. Check to see if iTunesHelper is listed and not unknown. If it is unknown, delete it. Then go to Finder, find iTunes, and Control-Click to Show Package Contents. Go to Contents:MacOS and you'll see iTunesHelper. Now just drag this into the Login Items window in System Preferences and check the Hide box. Restart your Mac and iTunes should now start whenever an iOS device is connected.
