Implemented CrashOnLaunch on a Mac?

Hey, im not sure if this is a mac thing of if im doing something wrong or if im just stupid.
I just moved and only have my macbook air available for the next 3 months so;
I tried starting MYG on this and all I got, was that once the window opened it basically loaded a bit but at the part where the Mojang logo is supposed to show it crashed with this log.

Help

 

hmm, i just downloaded and installed java 8 :l, lemme check if it didn't delete the old java?

edit:

 

I updated before I captured the log up there

 

Yeah, that worked, weirdly enough? Thanks
