Have you tried force updating in the options tab? If that still doesn't work, follow the trouble shooting steps in my guide (linked in signature)

I had a conversation with the admins, they said I can submit a pull request on the GitHub, and what that means is that it could possibly end up on the download page. :D! P.S, I Checked, and it does update successfully. Sadly, no download on the forums. But mabie on the FTB downloads page soon!

Also I would like to know what problem CryoFear is having. I may be able to help him out sense i have a little experience with java and MC not playing nice.

Opps i was on page 3 and not page 4, Anyway i think CryoFear is having Network issues. Or mabie his java is wrong. Have you tried to do the steps in the beginning of this thread? It may help your problem. If not try re-downloading the launcher.

Are you using my launcher? Did you download it before the admin took it down? Also my launcher does work with updates. If that is was your wondering. Also. You cant just type in the commands that are in the beginning of this thread. You have to change directories into the place where the launcher is. So if you haveit on your desktop. You open terminal, do "ch Desktop" and then do the commands. If you have a a folder on the desktop do "cd Folder name" and it should work.

You need to give us the full log and exact command you used if you want any attempts at help.

Do you still have Java 6 installed? Or do you not have Java 7 installed? Looks to me like it just stoped working. The terminal will give our errors and complaints, you cant do a thing about it. But it seems unusual for it to just stop. It set up the Ram, it loaded the proper set up Jars for minecraft. Everything is fine until it loads the minecraft.class. Ive never had this issue, (or mabie i have, i dont pay attemtion to the termial unless something stops working). Also, i say that you went into the "minecraft" directory, is that where your Launcher is? Because the Java fix command only works if the Jar is in the same directory as where you hit the command. Also looks like the Launcher doesn't have the correct permissions to go into the directory where all the minecraft stuff is stored. If you look it sais "Fixed Minecraft Path: Field was private static java.io.file..." Thats a red flag (to me) that something is private to external users and programs that shouldn't be. ALSO, i tried to launch the DireWolf20 pack and it didn't work. (the download didn't finish) but thats because I packaged the FTB launcher to to a .APP Application so i wouldn't have to take those painful steps.
If you would like to have the Launcher i made that automatically launches FTB, im sorry but i cant post it here. The admins would most likely take this post down or something ugly and i would get into trouble.

So I tried doing all this and couldn't find the extension file to rename .icn so i was just messing around and found that opening the app bundler then selecting the ftb launcher .jar file then hit create app it should create a app folder then u just open and it works.

I dont wanna look like a retard here or something, but how do i open the terminal (New Mac user)
A few ways:
1) Go to Applications>Utilities and run the Terminal app. You could also make a shortcut to it.
2) Cmd + Space to open Spotlight, type in Terminal(partially or fully) and run it from there. I usually just do this.
3) Open Launchpad and find it in there.

Amongst a number of other methods lol.

Oh wow, it works. I thought I was using Java 1.6 already, though. Why wasn't it working before?

EDIT: Yep, according to java -version, I have

java version "1.6.0_41"
Java(TM) SE Runtime Environment (build 1.6.0_41-b02-445-11M4107)
Java HotSpot(TM) 64-Bit Server VM (build 20.14-b01-445, mixed mode)
Which is Java 1.6. Doesn't the script specified switch from Java 1.6 to Java 1.6?

Hi,

Even by using the code in the first page I still can't get FTB to work on my macbook. It doesn't quit as it used to do but it gets stuck on "Converting world" whenever I try to create a new world.

Here's my pastebin log:
http://pastebin.com/bv6DnGxa
Ant help would be much appreciated.
