Launcher appears, but not loading

[InstallingIsHard]

I have the latest java version 

Running mac os

I cant put a photo because of fudging only 81.92 kilobytes allowed and i even made mc as small as possible but it was still too large so ill give a description

Screem sais 1.7.10 at the top 

Loading launcher is pure black for the screem u see

Edit: ill just use a website called lighthshot link http://prntscr.com/dk0rv2

Edit 2: i found the solution, but its frustrating. I add optifine to make sure i dont lag, it works on my computer, but it doesnt work on my mac maybe its just how mac's work Either way please tell me a way to get it working
