I just figured out that Forge is doing this, this problem is fixed in the latest forge build, which unfortunately is for 1.4.2.

I've almost managed to fix it. Type this in console: cd ~ open .bash_profile This should open TextEdit with your .bash_profile file. Now at the bottom add this, save and restart your computer: # Set JAVA_HOME to Java 1.6.0 to work with Tekkit JAVA_HOME=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home export JAVA_HOME It'll make your system run with Java 1.6.0 (java -version in terminal), however for some reason it will not fix the tekkit problem (at least not for me).

Alright, hmm... This one may work. It executes the JAVA_HOME set command and right after that it runs a selected jar using java -jar. I don't think cd is required for it to work since it only navigates to a directory. EDIT: Now I've infected myself with this problem too (by installing Java 7). :D

I've just made an AppleScript for this, you can download it here. All it does is execute export JAVA_HOME=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home. I can't really test this because I don't have the problem, however I'm pretty sure if you put this in your dock and make it start at login it would work.
