I purchased an Apple TV for the main purposes of streaming content from one or the other of the three Macs in the house, and for mirroring a display in order to be able to show some PowerPoint (Keynote) presentations. For $179 US, I got something that will connect to my existing 43-inch television, bigger than any monitor I would or could own, with other abilities besides the aforementioned, so I'm not at all unhappy with my ppurchase. However, I now have the thing set up, and have more questions than I did before taking it out of the box.
Contrary to advice I was given before I opened the box, VoiceOver must be manually enabled after the device boots, similar to how it works on an iPhone, when the language choice screen is displayed. It had been suggested to me that a pre-recorded message would play, telling me how to continue setup with VoiceOver, similar to how it works on MacOS. That one threw me for a few minutes, until I finally pressed what turned out to be the HOME button three times. I got lucky.
2. Where do I go either online or on the device itself to learn what the buttons do? I figured out that the button on the upper left of the remote, the one that's concave flat, is HOME. But there is also a rocker, at least two almost-flat buttons, and a concave bowl button--that is, a button that feels like a bowl rather than one that feels like a circle with a rim. So, what do these buttons do?
3. Is the device always on, or is sending it to "Sleep Now" in Settings the accepted way of turning it (and my TV) offf?
4. Since it's Airplay capable, can I just stream any old content to it from the house Macs, and if I do, do I get audio as well, or do I have to mirror the display to get both audio and video?
I looked all over AppleVis but couldn't find a new-Apple-TV-owner's getting-started document, here's hoping someone can come to my rescue, with my profound thanks in advance.
P.S.: During setup, I was asked for my TV provider, and picked Verizon Fios from the list. What did that get me? Every bit of content I've found all seems to come from third-party sources like NBC, and everything from iTunes is a purchasable item. So what is Verizon Fios going to do for me with this device?
