So I've been trying to install mods for the past 2 weeks on my mac and it doesn't work with the new launcher. I'm trying to install optifine, forge with TMI and I get the code -

Game ended with bad state (exit code 1)
Ignoring visibility rule and showing launcher due to a game crash
Deleting /Users/lindlerch/Library/Application Support/minecraft/versions/1.6.2-Forge9.10.0.804/1.6.2-Forge9.10.0.804-natives-1374993609500749000

Also i don't need Forge but I thought it would fix the problem. I have checked everywhere and can find a solution. Please Help. Thanks
