title: Installing SBT an Mac OSX 10.6
body: <p>I am trying to get SBT running on my Mac Operating System. 
  So far, I downloaded the Jar-Launcher and installed in into the /bin folder. 
  Then I created a SBT script, containing the following lines: </p>
  
  <pre><code>export PATH=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin:$PATH 
  java -Xmx512M -jar ` $0` /bin/sbt-launch-0.7.7.jar "$@"
  </code></pre>
  
  <p>When I call SBT on the Console, I receive the following series of error messages: </p>
  
  <pre><code>&gt; /bin/sbt: fork: Resource temporarily unavailable
