I don't really understand this and wouldn't be able to know what the main class is and stuff. Would anyone mind doing this for me as I am generally confused in this area of computers.

Don't know if I mentioned this, but my main computer died about a month ago and it will be about 4 months till I can build my next one. I am just trying to have a way to pass the time. Also Java works and such because the normal Minecraft client works, but I can't install mods on it so it becomes boring, then I went to Tekkit and then the launcher updated, not updating Macs to the .app, but just to a .jar, which my school blocks.

My mac won't load .jar files because it is a school laptop no matter what so I am having trouble being able to use these great mods, can somebody possible link me to an update .app file they might have? I tried to make one, but it would keep trying to open the .jar file in the .app. Please somebody help me, I have been trying everything for the past month and don't wanna move on from such a great game.
