I am having an issue with installing any of the forge versions into my mine craft 1.6.4 . Here is what is happening. I am on a Mac OS X version 10.8.4 . When I run the Minecraft forge installer version 9.10.1.871, I have also tried various other version, I run into an issue when it starts to download the files into my //Users/****/Library/Application Support/minecraft folder. After I press the ok button to start the process runs until it gets to downloading the library files. Then an error message appears stating this. "These libraries failed to download. Try again. org.scala-lang:scala-library:2.10.2, org.scala-lang:scala-comiler:2:10.2" After attempting to re-download forge with various versions they all come to the same error. What is preventing this download from happening, and what can I do on my computer to fix this?
