does MacBook Pro need a DAC?


Not an engineer with a basic question. Just got a new MacBook Pro. It has AudioMIDI setup with format up to 96k hz.
I am using it by plugging in a cable into a headphone jack with the other end going into the receiver. A friend suggested I get a DAC. but I don't see what purpose would an additional DAC serve. Isn't my MacBook Pro already converting digital to analog signal? and is it doing it efficiently? enough for high quality reproduction? thanks in advance to all who respond

i listen to Tidal. Master tapes are favorites of course. Based on what you all said here, I decided to go with an option I can afford at the moment, Shiit Midi 3. My tastes are eclectic but tend to new classical music. Will post my experience with the DAC, after I get it. 
Badger_erich: Could you, please, post if/when you find a different solution from the one you currently use? I have a Rotel and B&W 805s at the other end. am already quite happy with the sound 
thanks to you all. I really appreciate you taking time to help me.
many thanks to everyone who responded to my original question.
following consensus advice, i got a DAC, cheap one, Shiit Modi 3.
And you were RIGHT as far as I can tell. Detail, detail, detail -- much more of it.
