BUMP! Exact same problem, I have mac 10.6.8- I open tekkit for the first time (makes a new tekkitmain folder and everything), I create a world and it starts to load, but when it gets to "Loading World
Building Terrain"
it freezes, no loading bar or anything, however same as terra it is apparently still responding. This is a recent problem, tekkit (with the new launcher) was working fine before.
Hexxit also works fine, it's just tekkit that does this... does anyone have suggestions?
