Gephi on Mac OS X Mavericks Quick Fix
I use the network visualization software Gephi almost everyday, especially when I am teaching Social Dynamics and Network Analytics at Kellogg. So, I was pretty concerned when I realized after upgrading my Mac laptop and desktop to the new Mac OS X Mavericks that Gephi was no longer working on either. Luckily, there is a solution: Installing this Java update from Apple seems to fix everything up.
I get this error: java.lang.NullPointerException

Hi Ali,
I'm afraid this one is beyond me. Looks like a Java issue, but that's about all I can tell. Sorry I con't help more.

Hi, I'm able to open Gephi in OSX, it works just fine. Can also see my data by the graphs are not working. It just gives a blank screen. I have the updated JAVA from Mac. Please help
You may have accidentally closed the graph window. While in the Overview tab, select Graph under the Window menu.
I'd really love to try out gephi, but I've had the issue referenced here on 2 different Macs and have never gotten it to run.
Have you tried the newer Gephi 0.9.1? I believe they have fixed this issue. If you still have trouble try using the nightly build version here: https://github.com/gephi/gephi#nightly-builds
