PLEASE HELP!

Either you failed to install whatever mod you were trying to install correctly, or certain .class files were missing from the download. Either way, go into:

{your username}/Library/Application Support/Minecraft/bin

and delete minecraft.jar.

This will not delete any of your previous saves. It will simply force Minecraft to reinstall the .jar file and reset your mods. If you are installing a new mod, also be sure to delete the META-INF folder in your minecraft.jar; otherwise, it could lead to unexpected crashes like you are experiencing.

Thanks guys
