How do you think that I should go about fixing this?

Also, I am running Mac OSX 10.6.3.

So, I am running Minecraft on my mac and I installed forge on my client using the installer no problem. My friends and I wanted to play a modded survival together so I made a server (running the jar using start.command and everything, so I could connect to it and it was playable) and then used the same installer to install forge on the server (I used the folder in which the server files were). Then i doubleclicked the forge server jar file and it made the mods folders, libraries, etc. Then I replaced the minecraft server jar in the start.command with the forge file and ran it again. It got somewhat far and then I got this error: Last login: Sat Aug 31 20:10:21 on ttys000 /Users/johnsimpson/Desktop/Troy\'s\ Saved\ Stuff/minecraft\ server/start.command ; exit; new-host-3:~ johnsimpson$ /Users/johnsimpson/Desktop/Troy\'s\ Saved\ Stuff/minecraft\ server/start.command ; exit; Aug 31, 2013 8:20:52 PM net.minecraft.launchwrapper.LogWrapper log INFO: Using tweak class name cpw.mods.fml.common.launcher.FMLServerTweaker 2013-08-31 20:20:52 [iNFO] [ForgeModLoader] Forge Mod Loader version 6.2.57.845 for Minecraft 1.6.2 loading 2013-08-31 20:20:52 [iNFO] [ForgeModLoader] Java is Java HotSpot 64-Bit Server VM, version 1.6.0_51, running on Mac OS X:x86_64:10.6.8, installed at /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home 2013-08-31 20:20:52 [iNFO] [sTDOUT] Loaded 39 rules from AccessTransformer config file fml_at.cfg 2013-08-31 20:20:52 [iNFO] [sTDOUT] Loaded 107 rules from AccessTransformer config file forge_at.cfg 2013-08-31 20:20:54 [iNFO] [ForgeModLoader] Found valid fingerprint for Minecraft Forge.

Stuff/minecraft server/./crash-reports/crash-2013-08-31_20.21.01-server.txt I also tried running the minecraft server jar in the start.command and it just launched without forge. Can anyone help me with this problem?

Awesome! I'll ask if I have any problems.

Thanks, this helps a lot. I have a question. Do both of us on the server need to have forge installed on our single player minecraft in order for us both to use it on the server? Including the mod we want to install, do we need that to be installed on our single player as well?

Hi guys. So, my friend and I started a mine craft server today. We both have macs. We also decided to add two mods: More Swords and More Wolves. So, I found out that more swords and a lot of other mods use Forge, a program that I had never heard of because I had taken a break from the game. So, I tried to find a good tutorial on setting up forge on a server on a Mac, but couldn't find one. I saw some weird stuff like it has to be on single player as well, it downloads stuff, and so forth. Can someone please either give me a complete tutorial to mac forge, how to set up a server with it, installing mods and all that stuff, in a way that someone new to forge would understand, or point me to a good one. It seems like a really cool program and I really want to know how it works. Thanks, Troy
