Write an Automator/AppleScript script to download all the iTunes app updates

As far as I know, although both iTunes and the iPhone/Pad check automatically for updates, you have to manually start the process.

Yes, I know it’s a bad idea, because we almost always click “download all”. Even if you tell iTunes to remember your password, it won’t start the download automatically whenever there are updates. I have been looking for a way to do this since the iPhone 1G and haven’t come across a solution yet.

The common cause of this is when you have purchases in one library that belong to two Apple ID's. You will have to sign in to that second Apple ID to download those updates. This means iTunes is working as it was designed (although it is confusing since the Apple ID for each purchase is "hidden" in the info and not easily displayed.

A less common instance is when there is a problem with either the on line store or your local files that store the apps.

Here are two articles that will help if you simply have more than one account making purchases:

• Which account did I use to make a specific purchase?
• iOS: Changing the signed-in iTunes Store account
