Q: How do I stream from my MAC book pro to my Samsung smart tv

Hello dgt11,

Thanks for using Apple Support Communities.

If you want to stream to your TV from your MacBook Pro, then you would need an Apple TV.  However if you just want to use your TV as a secondary display, you can use a cable to connect to your TV.  I don't know what model of MacBook Pro you have, but if you take a look at the information in the links below, you can find out what your model supports and requires to connect.

HDMI - Cables & Docks - All Accessories - Apple Store (U.S.)

Take care,
