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.
Mod files are not runnable. Do you get any errors in the Minecraft Launch log? And where is that mods folder you created? Forge should have created it for you so you might have put it into the wrong directory.
