title: weka mac installation
body: <p>Recently, I bought a new macbook and installed weka. When I double click on the weka icon, it opens and after around 2 seconds, it closes.</p>
  
  <p>I've tried re-installing it several times and also tried different versions. However nothing seems to work.</p>
  
  <p>I've also searched the internet for a solution but can't seem to find one.</p>
  
  <p>Any help will be greatly appreciated!</p>
  
  <p>Thanks a lot!</p>
