I'm reluctant to download yet another screensharing software since I've tried dozens already and have been satisfied with none. All I need is something to allow my friend and I to share screens AND system audio while video chatting. According to what I read, it seems like TeamViewer is exactly what I need, but is it really? As mentioned before, I've tried a ton of other similar things and none of them work the way I want.
And, since it's just my friend and I, that counts as private use and I would be able to use it for free, correct?
...Basically we just want to watch TV shows and other things together since we live quite a distance away... I'm really hoping TeamViewer is the thing to use, and hopefully it's also secure. If this information is needed, I'm using Mac OSX Yosemite and she is using a MacBook Air, El Capitan.
