I'm not a pro, nor a mac user but your error log makes me deja vu. I've solved errors like this, like this;

 

Force update, delete meta-inf.

 

Before you put your mod files into jar, make sure that "they're not deleting each others' classes"

You can combine'em  in to a file before putting into jar.

 

(Don't know your level but) when you put mods into the mods file, you don't unzip

 

This is my best.

I'm just saying... If you didn't try it yet, just try it now. Better than nothing.

I'm also a mac user (running 10.8.1) and I'm getting the exact same problem.  What do you mean make sure that "they're not deleting each others' classes"? I copy forge's class files into my minecraft.jar and replace all of the ones with the same name, is that wrong?

I mean for example, you installed A mod, then installed B mod... If those mods have same class files, B deletes A's files.

 

Take a look at this. Could be more Mac-ish than me: http://www.minecraftforge.net/forum/index.php?topic=832.0

 

What you say is not wrong for me, but they're talking about something different for mac. Read that topic.

Unfortunately with Macs, if you copy mod files and subfolders into the "minecraft.jar" folder (that you make while installing on a Mac) and "Replace" old files, if there were any subfolders of the same name already in the "minecraft.jar" folder, then it will remove everything from those subfolders and just replace them with the new files.

 

What this means for you is that, since FML has a "paulscode" subfolder (containing the file "paulscode/sound/codecs/CodecIBXM.class"), everything that was already in "paulscode" goes away - your entire soundsystem.

 

To get around this, you'll need to copy over everything else from that forge universal zip except for the "paulscode" subfolder, and then go down into the "paulscode/sound/codecs" subfolder and copy "CodecIBXM.class" directly into the "paulscode/sound/codecs" subfolder of your "minecraft.jar".  Or else use a mod installer/launcher program like Magic Launcher to avoid touching the "minecraft.jar" at all.

 

(It's a shame, really... if it weren't for that single "CodecIBXM.class" file, there'd be no problems with installing Forge on a Mac in the usual way.)

Thumbs up. It's really ridiculous by the way:) So, [solved] I guess.

Ya well we need that class or else users bitch about audiomod compatibility.

However in the last 10 builds or so i've forced forge to be bundled with all of /paulscode/ to hopefully resolve this situation, its crappy and stupid I know, but... macs.... -.-
