When you say "You type in a formula" [if you're well trained in Mathematica on
the Mac then you obviously typed Sin[x] not sin(x)] and say that you get the
spinning cursor that implies the front end will launch but the kernel will
not access properly. This is *most likely* (but not certainly) because
you failed to remove all of the old Mathematica 1.2 files when you upgraded
to 2.0.  If any Mathematica files are left in /NextApps or /Nextlibrary
remove them and re-install Mma 2.0.  This can also happen if you use the
"Gourmet.fix" trick I've posted a few times (ie making dummy directories
in /NextApps and which you link to the new ones) but upgrade without
removing those directories first.  If you can launch the front end then 
Mathematica is in the path, but if you can't evaluate anything it means
its not finding the kernel. The spinning disc probably means it's in a 
search which will not terminate, ie it doesn't look for hte kernel in some
directory, not find it, and give you an error message, so it's in a 
recusive call. Remove all the old (1.2) stuff and re-install.
