I don't understand. I have the latest version of Forge, is this something else?

And now it says something about an upload path when i try to upload the image of the error report! It says: Forge Mod Loader has found a problem with your minecraft installation The mods and versions listed below could not be found: Forge: minimum version required is 7.8.0.688 The file 'ForgeModLoader-client-0.log' contains more information

I play minecraft on a mac,and I was trying to update Forge. After i installed, this image came up came up. How do I fix this?
