It is known that the mac launcher does not work, minecraft crashes on launch.

To fix it run
Code: 
export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
in terminal just before launching the launcher from terminal.

or

You can download an app file <coming> to do this for you

The full process for launching properly is
  1. Save the launcher jar on the Desktop in a folder called ftb
  2. Open terminal and type

    Code: 
    cd ~/Desktop/ftb/
export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
java -jar FTB_Launcher.jar
  3. The launcher should launch and work properly

IT LIVES!!!!!

Thanks! Now if only there was a way to do this without copy-pasting your post into the terminal every time.

Googled it. came up with Automator workflows saved as application format. Well, that was easy O_0

There is a plan (I am fairly sure) to release the launcher in application format for mac that will do this. (Will be linked replacing the crossed out area on the first post). However, good solution.
 
Just like with Vanilla server you can make a launch.command file
Heres a one I threw together based on the code above

http://dl.dropbox.com/u/16704552/launch.command.zip

Just unzip and drop it into the same folder you have the FTB.jar in and double click.
If you get an error saying it doesn't have permission, open a new terminal window type in without the quotes "sudo chmod +x (drag launch.command here)" then hit enter.
Make sure you have a space between the "+x" and the file path.

Have any of you tried simply starting it with this:
Code: 
cd ~/Desktop/ftb/
java -jar FTB_Launcher.jar

This has worked for me. I find it weird though that the game cannot run without starting it this way. Especially since it doesn't throw any errors, but simply closes...
Have anyone investigated the cause for the odd behavior when launching the jar by double clicking it, or is it still a mystery why it acts the way it does?

If you have java 7 installed it will not work on OS X. If you are interested, read http://lwjgl.org/forum/index.php?topic=4711.0 .
 
I have Java 7 installed... and it works fine for me.. at least im 98% certain i have Java 7, will have to check when i get back home..
I know of the issues with LWJGL, have been following the development of that thread for a while.. wanna get the new version. The one that ships with Minecraft has a nasty memoryleak when it comes to age-changing in Mystcraft (possibly also Nether/End, but not sure)

This one works the best, thanks!

Also, you can do an alias and put it anywhere you want, and rename it however you want

Do you mind if I include this fix on my CP&S document?
This is what I would put:
# Mac crash errors and Login problems: check out this thread here: the OP

You can open the terminal in two ways:
  • Go to Finder, click on "Applications", scroll down to "Utilities" and double click to open it. Scroll down to "Terminal" and double click on it.
  • Hit Command + Space (to open spotlight) and type "Terminal" (without the quotes).
