Is there a reason the new launcher wouldn't work for some? I have three friends (two who use Windows 8 and one who uses a Mac) who are unable to see newer mod packs on their launcher. They both have tried updating their launcher, deleting their launcher and FTB folder and downloading the new launcher. In the end the only solution we found for those with Windows 8 was to transfer my launcher file and folders. I have no solution for my friend with a Mac. Any thoughts?
