Is there any way to prevent iTunes from starting on a Mac under OS X Leopard when an iPhone is plugged in?
Or open System Preferences -> Accounts -> Login Items and remove the "iTunesHelper" entry.
Open iTunes> Preferences>Devices>General tab and check "prevent iPods [etc] from automatically syncing"
On OS X 10.8 Mountain Lion this option has moved very slightly. Find it under:
System Preferences -> Users & Groups -> Login Items
Then remove the iTunesHelper entry.
I prefer it like this:
- go to iTunes -> Preferences
- select Device tab
- check the prevent iPods,iPads from syncing automatically
This should solve this issue.
