Not able to launch ModPack Ultimate (v1.1.2) 1.4.7


I’m trying to start FTB Ultimate (v1.1.2) on 1.4.7 on my MacBook Air and it wont start. The consoles last line is
”(DATE) [INFO] [STDOUT] LWJGL Version 2.9.2"
please help me
Oh and btw it used to work so I could normally launch it and play but suddenly the same day when it still worked it couldn’t start it.


Post a log, instructions for that can be found here:
