I do have a Windows 8.1 dual boot (bootcamp) but it's not the same.
Did you (or anyone) find a fix for this? I can't play any technic modpack because of this (OS X Mavericks, 10.9.0 GM).
I've updated to the latest LWJGL and tried both Java 6 and 7 but this issue still persists.
I doubt Mojang will provide a fix for this as it only effects -1.7.2 versions.
IPv6 on Minecraft seems to work for me on Linux, but not on Windows.
Seems like a two line fix, why is this being put off?
