I don't want my mbp to sync the iPad
I connected my father's iPad to my mbp so I put his pictures on my external hard drive suddenly the iTunes page showed up and asked set as a new iPad or restore from this backup and I clicked on set as new iPad and it started to sync. Well his iCloud is different but in iPhoto when i click iCloud his photo stream is still there.
My question is how to disable his iPad and i want it not be considered as one of my devices.
