ech weiss ned, wievell du vo computer verstohs, ech kapier nix aber ech starte de launcher via terminal:

cd ~/Desktop/FtB/
export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
java -XX:MaxPermSize=128M -Xmx2048M -Xms2048M -jar FTB_Launcher.jar

cd ~....... do chond halt de ordner äne wo de launcher denne esch

das brengt aber glaub ech nüt, darom im launcher drenne:

options --> advanced options ---> additional java parameters:

-XX:MaxPermSize=128M -Xmx2048M -Xms2048M

sit ech das gmacht han, hani eigentlech nie meh problem gha
