Minecraft download malfunction?

So I had minecraft on my old computer which was a toshiba and i recently purchased this macbook since the old laptop was old and i needed to upgrade. I've been trying to download minecraft but after the launcher pulls up and i hit play nothing happens. I have an adobe flashplayer and java. The only launcher theyve provided was 1.7.9. What am i doing wrong?

any feedback appreciated

Ello, could you be more specific when you say, "Nothing Happens"?
Are you sure you're waiting long enough for the game to start?

Oh, and if you could… Starting a griefing team and would like to get in contact with a graphic designer. Know anyone?
