The new Apple TV has a USB-C port. It’s got some great uses. One of which is that you can use it to take screenshots through Xcode. To do so, you’ll either need a USB-C MacBook or a USB-C to USB adapter. Once you’ve plugged your computer into the back of the Apple TV, open Xcode and choose Devices from the Window menu at the top of the screen.
From Devices, click on your new 4th Generation Apple TV. You’ll then be greeted by a Take Screenshot button. Click on it.
You should then see the screen from your Apple TV. Now, good luck with that pose… Now that I can take a proper screenshot of an Apple TV I’ll have to meditate on whether or not I’ll someday write a book on the darned things…
