This took me a while as well
As this is a show-stopper for every normal Mac user here the steps to get it running on Mac OS X 10.9:
download and install this: http://support.apple.com/kb/DL1572
delete your gephi settings dir: rm -r ~/Library/Application\ Support/gephi
find your java home with /usr/libexec/java_home -v 1.6, it should print something like /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
if there is a message about being unable to find any JVMs matching version 1.6 something is wrong, fix it
edit /Applications/Gephi.app/Contents/Resources/gephi/etc/gephi.conf to set your jdkhome e.g. like this: echo “jdkhome=\"$(/usr/libexec/java_home -v 1.6)\"" >> /Applications/Gephi.app/Contents/Resources/gephi/etc/gephi.conf
start gephi and open the Les Miserables sample, if you see the graph good.
check gephi’s about for the line saying Java: 1.6.0_65; Java HotSpot(TM) 64-Bit Server VM 20.65-b04-462
as simple as that ^^
This critical bug was reported over a year ago… Until Java 7 is supported I suggest solving it similar to other apps like yEd by a dialog guiding the user through the installation of Java 6.
In the meantime please just check the Java Version on startup and properly explain the problem and how to solve it instead of that ugly nothing saying “unable to load libjogl_awt" error message.
We all like gephi, but due to this i guess only < 1 % of your mac users are left 😦
