I could install this version of
Mac OS X 10.7.2 and it runs properly but when I do this on
10.7.4 installation completes normally but it doesn't run and the bug report screen comes up!
If you have installed Unity before upgrading to 10.7.4, it runs OK and everything's fine, but if your try to install unity after upgrading to 10.7.4, then you are going to have this problem!!!
Any ideas? other than reinstalling the whole OS from scratch...
