Hi all, i'll be fast: i downloaded the launcher for mac os x, when i open it, i enter my username and password, it says "launching", and then "100% no update for tekkitmain found", then a white screen open and says "minecraft validated, launching..." so i remain a few seconds with this white screen (tekkit) and then it closes.
I'm going insane. Please help me, answer if you have just a suggestion, every little help will be appreciated. Thank you
