How can I prevent iTunes from auto starting when I plug in an iOS device?

i know we already have topics about it, but i did not found my solution.

So i don't want to start iTunes, when i plug in iDevices. We have like 300 iPads, and i am using the configurator. iTunes still starting automatically, even when the Configurator is running.

I really don't want to turn off this settings under the iPad summary screen one by one. I have already turned off the autosync.

Solution 1:

Run this command in a terminal to disable that behavior:

defaults write com.apple.iTunesHelper ignore-devices 1

Solution 2:

The only way I know to not have to set it for each & every device individually is to disable the iTunesHelper app from Users & Group control panel
