Home Sharing is a super-handy feature of iTunes, Apple TV, and iOS thatlets you access items that exist in other iTunes libraries. Those other
iTunes libraries can be in another account on the same Mac, or on a
Home Sharing lets you do a bunch of different things with the music, movies, TV shows, and apps in your iTunes libraries:
* Copy items from other iTunes libraries to
your own iTunes. This is a great way to avoid paying more than once for
the same thing.
* Play content from one machine on another machine. Stream from iTunes to Apple TV, or pull from iTunes to Apple TV or your iPhone.
* Remote control your iTunes or Apple TV.
To use Home Sharing, both iTunes must be on the
same network, that is, connected to the same router over wi-fi or Ethernet cable.
To play an item that was bought at the iTunes
Store, that iTunes must be *authorized* with the same Apple ID that was
used to buy the item.
#### Enable Home Sharing
This is the most crucial bit to know: *Enter the **same Apple ID and password** in every
iTunes that will use Home Sharing.* Any Apple ID will work, but be
![Turn On Home Sharing]
#### Using Home Sharing
To access other iTunes libraries, those iTunes must
be open. If it’s iTunes on another computer, that computer *must be awake*
with *iTunes open*.
On your iTunes you see a **Sharing** section in the
sidebar. Select the library you want to get items from, and wait till
the main window displays items in that library:
![Shared Library in iTunes Sidebar]
Now click the triangle to the left of the shared
library name. You see categories of items, as well as other
sub-categories with their own clickable triangles:
![Subsections of Shared Library]
Items in the category you select are display in the main window. You can
play music and video tracks, but the great thing is you can drag items
to your own library to copy them into your iTunes. Your library is the
first section in the sidebar:
If you want to play an item bought under a particular Apple ID, you must
authorize your computer with that ID. A maximum of 5 computers can be
authorized for a single Apple ID. (Always *deauthorize* computers before
you get rid of them!) You need the Apple ID and the password to do this:
![Authorize This Computer]
**Bonus tip:** If you forget to deauthorize a computer before you sell it, and then find yourself running up against the message “You Have Already Authorized Five Computers,” you can Deauthorize All Computers in your iTunes Store > Account. Then all you have to do is reauthorize each device you still own. (This is all way less dramatic than it sounds, but you should know that it works only once a year.)
#### But Wait, There’s More
If you have an Apple TV, turn on its Home Sharing: Go to **Settings >
Computers**. Now you can play items on your computers while sitting on
the sofa looking at the Apple TV. (This doesn’t work for the original
silver Apple TV, but there are other ways to accomplish the same thing on
Home Sharing on your iPhone and iPad is in **Settings > Music**. With
Home Sharing on, you can play items in other iTunes libraries with the
sound coming out of the phone.
Finally, the neatest trick: Download the free *[Remote](http://itunes.apple.com/app/remote/id284417350?mt=8)* app from the iTunes Store to your
iPhone or iPad. When you authorize the Remote app with the same Home Sharing ID you’ve used elsewhere, you can control your Apple TV or iTunes on your computers. That’s entertainment!
