Infinity launcher won't finish

[ihasbubblez]

I am currently trying to download the Infinity 1.7.10 modpack. I click install and it downloads the files and brings up the screen that says Mojang and starts downloaded all the mods and stuff. Then once it gets to 7/7 Completing Minecraft initialization, 171/171 mods loaded, 1/26 Language something and doesn't load anymore no matter how long I wait. Please help (btw I'm using a mac)
