This version requires Java 6.  Please see the instructions for updating your 
Mac at:

http://www.unidata.ucar.edu/software/IDV/docs/userguide/Systems.html#os

We have found that some Macs are having problems running the IDV from the IDV 
application launcher (IDV.app).  If that's the case, then download the nightly 
build which has a fix for the app or use the runIDV script in the install 
directory. 

In either case, you'll have to update to Java 6.
