Sadly I cant test if that fix works as I reinstalled my mac, the reinstall fixed it so not sure what the issue was. Thanks anyway!

I got around the issue using a Parallels VM, It's not the best method but it works. Suppose I'l be playing tekkit on Windows more often :D

Thanks for the reply, Yeah I removed the 'technic launcher' folder and restarted tekkit and tried using the linux version(jar) . All this occurred either when I upgraded to 12GB of ram or when I installed eclipse + java JDK. I did both within a similar timeframe.
