I can't get Unity to launch after instal?

I am running an 8 core mac 3.0 with os 10.7.5 and 32 gigs of ram. I believe I am way above the minimum requirements. I install good, but when launching it just hangs up (even left if trying to open for a full day, lol. I have tried the option open technique as well as full uninstall and reinstall many times, nothing seems to work.

Any Suggestions?
