When Minecraft 1.6 came out I quickly went to get the launcher and as of downloading it and trying to log in I was given a strange error message saying, "there is a bug in lwjgl which makes it incompatible with OSX 10.5.8 please go to New Profile and play on 1.5.2 for now Sorry!". I asked my cousin who has helped me with issues with loading screen and other issues such as lag or crashes. After he looked at it for a half of an hour and was stumped he told me to delete my minecraft folder and start over again. I did that 4 more times and the same issue happened. So now I ask you guys, do you have any ideas of what this could be? And/or how to fix this?
