Apple recently added a new feature to iTunes. It gives users the option to download things at a later time. This can be useful if you are downloading full seasons of TV shows or big music collections, such as that Beatles box set.
As website iMore reports, when you purchase a TV show of movie, you get three options: Download Later, Download and Download All. Perhaps you are on your MacBook Air, and you want to download an entire season, but you’d rather wait until you get home to your other computer, which has more storage capacity. Another example may be when you purchase something while on your iPhone, but want to avoid using too much of your cellular data.
You will need iOS 6 or iTunes 11 for this new feature to work. Otherwise, the additional options won’t be available.
