Interesting, can you give us the md5 of this file: /Users/edulzo/Library/Application Support/minecraft/libraries/net/minecraftforge/minecraftforge/9.11.0.883/minecraftforge-9.11.0.883.jar

It should contain all of the classes, and it *looks* like it's in your classpath.

When you run it normally using the mojang launcher, what happens?

Tested running it on the standard launcher, same error (Runs it, but no window appears), checked for the md5, and funny enough, it was missing..

I'll add more clarification here... when I went to /Users/edulzo/Library/Application Support/minecraft/libraries/net/minecraftforge/minecraftforge/9.11.0.883/minecraftforge-9.11.0.883.jar, I got to /9.11.0.883, and there was no .jar in it, which is weird, any ideas as to why that is, or a way to fix it?

Ya, use our installer. Our installer will add the libraries to the correct path.

Installer doesn't run, my dad did something with my computer and made it so I can't execute jar files... (Got Minecraft forge .jar from my friend). any way to manually install?

http://www.youtube.com/results?search_query=how+to+run+a+jar+file&oq=how+to+run+a+jar+file

Running a jar is really, really simple.

I know HOW to, my dad just set it so it denies permissions to run it...

your dad doesn't allow you to run java?

How do you run minecraft?

You should talk to your dad.

Not Java, just unknown executable jar files, Minecraft launches in a .app, so it basically is like a bypass... and he won't change it ._. Is there a way to manually install Minecraft Forge?

Yes, but it's a pain, You need to download the libraries manually, place them in your libraires folder.

Copy the 1.6.4 folder

Replace the json with the json in the installer's sub-section.

Simplest solution, Talk to your dad.

I did, he won;t change it, he's worried I'll run something stupid... where could I download the libraries?

Then have him install it for you. I'm sure there are manual install instructions out there. I am not about to recite them all here.

However, if he doesn't trust you to run the Forge installer, then he wont trust you to run mods. Because mods are exactly the same as the installer. Runnable java code.

Seriously, this all boils down to you needing to talk to your dad about what you can and cannot do on your computer.

Successfully installed it manually, no more errors here... problem solved, thanks for the help Lex!
