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?

Need code to offer help. Do you have an infinite loop in a start function?
