Apple TV Set Up


I would appreciate some advice on my digital streaming issues. 

My system consist of Vandersteen Treo CT, Mimas with DAC, and the older AppleTV Streamer (model A1469). The AppleTV is connected via Ethernet cables. I digitally stream with Tidal from a MacBook Pro via Wifi. The download/upload speed  for my MacBook is about 230/11 Mbps.

The AppleTV has the latest software update. 

Question 1
Every-time I wish to play, I open my MacBookPro, open the "System Preferences", then "Sound", then choose "Apple TV".
Is there a shorter path or can I set up my MacBook differently?

Question 2
My MacBook sometimes looses connection (AppleTV gets disconnected). I then have to manually connect "AppleTV" again. Why does this happen?

thank you all in advance!

The reason there are so many Node 2i's for sale is that a month or two ago Bluesound came out with an updated Node model they now simply call the Bluesound Node.  Apparently it has a faster processor and updated DAC, and sells for exactly the same price as the Node 2i it replaces.

Why is apple tv used toview stuff on a computer?

apple tv has an ap.

this all very hard to follow
I've been a dedicated Apple user since the '80s, and as much as it hurts me to say it, they're just not an audio company. 

There's no point in paying for Tidal only to degrade the signal downstream, as others have said. 

I'm still 'new' to this hobby and come here for advice, nearly always, not to give it. But when I ditched a 'beginner' tool like my Emotiva XDA-2 connected to an earlier AppleTV, and replaced it with a used Lumin D1, the change was massive. I control the Lumin with an iOS tool, but the signal stays ethernet into Lumin, RCA to amp. 

Best of luck. 
If you don't have the sound icon in your menu bar, I'd add that; it's a faster way to send the sound to your Apple TV.  Open System Preferences/ Sound, and check the box at the bottom of the dialog (it says it's just for volume, but it also lets you choose Apple TV as your audio source)
