Purchasing content in iTunes is a simple way to be able to access it across all of your devices. Whether it is an Apple TV, iPhone or iPad, as long as it is set up with your Apple ID, you can access your content. But sometimes you just want to watch a TV show or movie without downloading it. Fortunately this can be done in iTunes on your Mac computer.
Watch an iTunes Movie or TV Show Without Downloading It
I love the Apple TV for its’ ability to stream iTunes content directly to your TV, but its not the only device that is capable of accessing your iTunes content in the cloud like this. So read below to learn how to stream iTunes content to your computer.
Step 1: Click the iTunes icon in the dock.

Step 2: Click iTunes at the top of the screen, then click Preferences.

Step 3: Click the Store option at the top of the window.

Step 4: Check the box to the left of Show iTunes in the Cloud purchases, then click the OK button.

Step 5: Select the Library option at the top-right corner of the iTunes window.

Step 6: Click the media type drop-down menu at the top-left corner of the window, then select the TV Shows or Movies option.

Step 7: Select the show or movie from the left side of the window.

Step 8: Find a show or movie with a cloud icon to the right of it, then double-click that video to start streaming it. DO NOT click the cloud button, though. That will begin downloading the video to your computer instead of streaming it.

Streaming is a good idea if you are running out of space on your hard drive. HD movies and TV shows can be multiple GB in size, which can fill your hard drive quickly. But if you want to download your files, you can always keep them on an external hard drive. You can purchase an affordable 1 TB hard drive at Amazon for this purpose.
