Mac Can't launch any modpacks

[runujhkj]

When I first downloaded the FTB launcher .jar about six months ago, I could run every modpack, but now I can't run any of them. The FTB Ultimate pack just vanishes, but the BMP actually gives me a crash log. I'm not sure what to include, but the error screen tells me to show someone the crash log .txt file instead of a screenshot of the Minecraft crash screen.

I'm running Mac OS X 10.8.5 on an Early 2011 MBP 2.7 GHz i7 with 8 GB of ram. I could just run FTB on Windows, but i'd really rather not reboot just to play Minecraft. :/ What should I do to get this to work? Anything else I need to include to help?

Welcome. We prefer pastebin.com for logs. You need to either downgrade to Java 6 or upgrade your lwjgl. If you choose to downgrade to Java 6 look here. If you decide to upgrade your lwjgl you will want to follow this guide, but substitute the '~\Library\Application Support\' folder for the mod pack folder. You will also need to upgrade each pack you wish to use as each pack has its own version of lwjgl.

I'm on Java 6 already; I fixed that so I could run Tekkit some time back. I upgraded lwjgl too, but are you saying that there are additional "minecraft" folders in the FTB folder in Application Support? I only thought to upgrade the one in vanilla Minecraft. I guess that makes sense.

Oh FFS. I could have sworn I got rid of Java 7. Well, upgrading the modpack's lwjgl worked, whatever that is. Thanks for the help, lavarthan!
