Got the newest Blender, works fine :D

Ok so it worked before and now I have Yosemite (which may not be the issue) it just closes and says 'quit unexpectedly' when I open it, so I don't know what to do. I even right clicked and click 'open' but it still had the same effect. If you like I can make a video of me trying to open it? Anyway, thanks for trying to help, I might delete and redownload it, and I'll let you guys know :)

Oh yeah thanks Campbell, I'm new to this website :)
