You are using a Mac and have Java 7. You need to do one of two things. Downgrade your Java to version 6 or update your lwjgl in each of your mod pack folders.

If you choose to downgrade to Java 6 check out this guide. If you choose to update your lwjgl then follow this guide, subtituting every reference to the minecraft vanilla folder with your mod pack folder. You need to do this for any mod pack that you are going to use if you keep Java 7.

I do not have a Mac unfortunately so the help I can provide is limited to what others post. If you tried to get Java 6 and it failed try again or update your lwjgl. Updating your lwjgl is not difficult. After you try both if you are still experieincing problems please post a new console log in debug mode to pastebin.com

I could not tell from your log, but if you did update your lwjgl inside the mod pack folders then the only thing I can think of is either a force update and/or a reinstall of the launcher Java and the pack. I wish I could easily tell you something else that would fix this. Please follow this guide to do that.
