Unity 5.0.2 OS X Yosemite: Editor Won't Launch

I just installed Unity for the first time on a pretty new Macbook Pro running OS X Yosemite. Every time I try running the program it opens the project selection page. Creating a new project (or opening a previously created project) results in either a spinning wheel that disappears as soon as the mouse is moved, then nothing, or a blank window titled "Unity 5.0.2f1" and a spinning wheel. Regardless of which of these two I get nothing happens afterward. I left it to load, assuming on first launch it might take a while to build a new project, for over 30 minutes with no result. Still a blank window.

Anyone heard of any errors like this on Yosemite? I have a gaming PC that I can run Unity 5 on, but I'd rather use Unity on the same machine I model and animate on.

Any help is appreciated. I've already submitted the issue through the Bug Reporter. Thanks in advance!

 

Not had this issue, working fine for me, latest OSX and Unity 5.0.2
