adameros

I just bought and install Minecraft 1.8.3. I then ran it and started a new world, saved and exited. I then downloaded installer for Forge 11.14.1.1337, and ran it. It tells me I need to run 1.8 first, and exits. I have verified its path to minecraft is correct, /Users/adam/Library/Application Support/minecraft. The installer does not generate any log file that I've been able to find. Here is the "latest" log from Minecraft: [19:05:29] [Client thread/INFO]: Setting user: adameros [19:05:29] [Client thread/INFO]: (Session ID is token:4c61cf446fae4c37a11c728c638122c5:9c394f1c77c14ab1ad3d4d17ce15779b) [19:05:33] [Client thread/INFO]: LWJGL Version: 2.9.2 [19:05:34] [Client thread/INFO]: Reloading ResourceManager: Default [19:05:34] [sound Library Loader/INFO]: Starting up SoundSystem...
