Hi, I used to play minecraft a lot but haven't played in the past 5 years. Before I played on windows, now I play on mac. About to get back into it and I wanted to use the traincraft train mod, I installed forge and when I load minecraft it shows the 4 default mods loaded, but when I put the traincraft mod and the too many items mod into the "mods" folder I created myself, the game launches with neither mod working. Yes, I am launching using the forge version like you're supposed to. I think the issue has something to do with this. When I go and double click on the traincraft.jar file, I get a message from my system saying "The Java JAR file "" could not be launched. Check the Console for possible error messages." I don't think that minecraft is able to run the .jar file and get anything out of it. Any help would be appreciated.
