I found a solution that worked for me. SPSS 20 did NOT work with the latest version of Java released this week (1.7 I think). I removed Java altogether and reinstalled Java 6 update 37 by going here: http://java-for-lion.en.softonic.com/mac/download. Now SPSS works on my computer without having to use the sudo command.
I have the same problem and tried your solutions, but nothing worked:
I tried the sudo thing: doesnt work (spss starts, but then nothing happens)
I tried to remove java 7 and reinstall java 6: didnt help
now i reinstalled java 7 and still have no clue how to start spss 20. i have a uni version, mac os x 10.7.5.
Is the problem only with mac os x 10.7.5?
When I disable the wifi connection, spss starts, but as long as i need an internet connecetion for my license, it doesnt help eighter...
I have the same issue too
On a MBA 2012 13", OS X 10.8 the stupid SPSS 20 just won't run.. Mine is also from the university. Everything with the installation went fine but when I tried to open it, the only thing that happened was the appearance of the small IBM SPSS License "window"... and that's where it's stuck
I tried the different Java versions, neither works for me, I tried to open it form the Guest user account, no luck there either. The only thing I haven't tried is the sudo command because I don't really know how to do it...
I would really appreciate any help, I have an exam in two weeks so i reaaally need to get it to work!
Check posted fixes on the IBM website
If you're using version 20.0.0 of spss,
I just ran into this problem but I think what worked for me was that after installing I just went a searching and found out that SPSS was sitting pretty amongst my apps in my launchpad...
I hope this helps someone.
Thats all folks!
