You likely need to downgrade your Java to version 6 (from Apple)

I've searched this forum and have seen a few others who have had this same problem. I also tried the steps mentioned in the "Fix Common Problems" post:

The launcher freezes on a white screen when I log in.

None of these fix the issue.

If anyone out there has it working, please help us OSX users out!

I've searched this forum and have seen a few others who have had this same problem. I also tried the steps mentioned in the "Fix Common Problems" post:

Did you try what I said?

[xaric]

Did you try what I said?

Yes, I did. Steps I took:

I located the java v6 executable on my machine, which is located:

/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin/java

 

I validated that with the command:

 

/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin/java -version

 

which yields:

 

java version "1.6.0_37"

Java SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)

Java HotSpot 64-Bit Server VM (build 20.12-b01-434, mixed mode)

 

At this point, I ran the following command to launch the technic-launcher targeting the v6 framework:

 

/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin/java -Xmx2048m -jar ~/Desktop/Technic Launcher.app/Contents/Resources/launcher/technic-launcher-latest.jar

 

The output of that command runs the launcher, which quickly shells out a new instance (with added command-line options):

WARNING: Rebooting with [java, -Xmx1024m, -classpath, /Users/[masked]/Desktop/Technic Launcher.app/Contents/Resources/launcher/technic-launcher-latest.jar, org.spoutcraft.launcher.Main, -Xdock:name="Technic Launcher", -Xdock:icon=/Users/[masked]/Library/Application Support/techniclauncher/launcher_icon.icns]

At this point, when I run Tekkit, I get the same problem: White window which then closes. No additional errors are displayed in the terminal and the log file appears the same as above.

I am guessing that because of the "WARNING: Rebooting" message, it is defaulting back to v7. How do I change control of that app to stick with the java version I've specified?

(By-the-way, your help and consideration is MUCH appreciated.)

This has also been happening to me on every version of tekkit, ever since the new update for 3.1.3 my whole tekkit has just messed up. I cant connect to servers either because I do not have the required mods or it crashes after a white screen.

got it working. you need to reset your PATH and then rehash and launch it as above (example for OSX only):

thibaultkick$ PATH=/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin:$PATH

thibaultkick$ hash -r

thibaultkick$ which java

/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin/java

thibaultkick$ java -version

java version "1.6.0_37"

thibaultkick$ java -Xmx2048m -jar '/Applications/Technic Launcher.app/Contents/Resources/launcher/technic-launcher-latest.jar'

Any idea how to do that on windows?

THAT WORKED! Thank you so much for your assistance. For Windows users, you can simply uninstall Java 7 if you don't explicitly need it. OR, you can edit your environment variables and change your PATH. Java 6 will be somewhere like: "C:\Program Files\Java ..." or something like that.
