Samsung TV wireless conection???

Can anyone help me??? I have (foolishly) bought a samsung 'smart' TV because the guy in the shop told me I could stream wirelessly from my laptop to the TV. I did ask if it worked for a Mac, he said yes.

Is there any way to make this work? Samsung suggested a 3rd party software might do it, but didn't know what it would be.

Any helpers out there???

Several options... Try setting up your Mac as a serviio or plex server (plenty or online tutorials or even go to plexapp.com), and then use the TV as a client. Short of that, you can use an HDMI cable and attempt to use the TV as your display. Short answer, there is no easy 1-2-3 or built in way to share wirelessly that I'm aware of. I killed a few hours at a relative's house this summer trying to make something work and gave up. Easier to just buy an ATV and hook it up, or set up a Netflix/Hulu account on the TV and be done with it. You can enable developer mode on the Samsung TV, but I'm not going to go down that road and be the impetus for someone screwing up their TV. Good luck!

Try TVMOBiLI A Free DLNA Media Server For Mac, Windows, and Linux.
I use this with my iMac and and smart TV

So now I am going to sound really dumb - but once I have TVMOBiLi - how do I make the TV and the computer connect to each other? they are in the same room (running on the same WiFi network) but not talking to each other!

Not sure exactly how to do this on a samsung TV. On my Panasonic I just go to internet> home network.
Sorry if this isn't much help but there is a support forum here Media Server For Mac, Windows and Linux • Index page
Good luck
