If you are like me, sometimes you want to sync your iPhone to get a new album on it or just some quick thing which happens really quickly and then you are stuck for an hour while your iPhone backs up every damn thing. Whats worse, is there’s a chance if your iPhone software goes bad you don’t want to restore from a backup because that could be messed up too. Better to reinstall from scratch. So the whole backing up thing is kind of pointless. Its bad, and I can’t take it anymore. So I opened the Terminal, and put in this:
defaults write com.apple.itunes DeviceBackupsDisabled -bool YES
Now, when I plug in my iPhone is syncs but doesn’t back up. Which is what I want, and I just saved myself several hours a week. Try it, it’s fun!
