Again please do not bump threads like this. It has been less than half an hour since you created the thread. We cannot help you with out more information than that. We can point you in a direction that might help. Start by following this
guide, paying close attention to part 4a for Macs. If you have Maverick you will need to have both Java 7 and update your LWJGL according to part 4a as you progress through the guide. After following that guide if you are still experiencing problems post a console log to pastebin.com using the 'Paste my log to pastebin.com' button on the console. The button should create a link at the bottom of the console that you provide to us so we can see what is causing the problem and may be able to help you fix it. If the button does not create a link then you will have to post the information from the console yourself into pastebin.com and provide the link it gives. Look
here to ensure your log is not deleted.
