Do you have the latest java update from Apple? If so, then you can try:
1) To run IDV.app with 64-bit Java SE 6 on OSX, you have to update the
JavaApplicationStub that comes with IDV. The architecture of this file
determines what version of java to use, but the version shipped with
IDV only has ppc and i386 architectures (not x86_64).
You can just copy the universal Java stub installed with the operating
If IDV was installed in /Applications/IDV_2.7u1, then:
You should then able to double-click IDV.app and it will run in 64-bit.
2) For command-line java programs, don't mess with the java symlinks.
If you set Java SE 6 64-bit as the preferred java version in the Java
Preferences, then you can put:
in your .bashrc to set the correct JAVA_HOME environment variable.
3) If you set the preferred java version, you can run idv from the
command line in 64-bit mode too. Assuming IDV was installed in /
Applications/IDV_2.7u1, then you can try:
java -server -Xmx1024m -Xdock:name=IDV -jar Applications/IDV_2.7u1/
This should run IDV in 64-bit mode regardless of whether you updated
the IDV.app binary.
Hope this helps,

When IDV 2.7u1 first came out (before the recompile), I tried the
Java 6 upgrade approach in Mac OS X 10.5.7. This turned out to be
more complicated than anticipated, and I still had only a hacked
solution. Here is what I did:
(1) Installed the recommended update and restarted: no luck
(2) Tried aliasing java to the binary java in the Java 6 directory,
verified version with java -version and restarted: no luck
(3) Found the Applications/Utilities/Java Preferences utility and
moved Java SE 6 64-bit to the top of the stack, and restarted: no luck
(4) Began hacking runIDV:
(a) added java alias from #2 above and ran: no luck
(b) discovered that JAVA_HOME was searched first, so I added
Success! Sort of...
...because I still cannot run IDV.app, even after setting JAVA_HOME
in my .bash_profile.
Did anyone get this to work with Java 6 in Leopard, and if so,
what's your secret?
