I removed it from the Applications Folder.
I then deleted everything I can find minecraft related from
~/Library/Saved Application State
So I was getting the "java.lang.reflect.InvocationTargetException: null" error when launching forge from the vanilla launcher with no mods installed. I removed Minecraft completely and reinstalled everything and reinstalled forge and same error.
