title: Trouble with installing eclipse themes in OS X
body: <p>I'm really new to OS X and I'm trying to set up Eclipse just like it looked on my Windows machine.</p>
  
  <p>When I go to <em>Help &rarr; Eclipse Marketplace &rarr; Popular</em> and try to install "Darkest Dark Theme.." (link below) it gives me an error message, right after clicking on "install" and agreeing on the license stuff, which says "an error occurred while installing the items".</p>
  
  <p>This is the message I get from the "details": </p>
  
  <pre><code>An error occurred while installing the items
  session context was:(profile=_Users_anton_eclipse_java-oxygen_Eclipse.app_Contents_Eclipse, phase=org.eclipse.equinox.internal.p2.engine.phases.Install, operand=null --&gt; [R]com.genuitec.eclipse.common.core.base.feature.feature.jar 1.8.4.201709142212, action=org.eclipse.equinox.internal.p2.touchpoint.eclipse.actions.InstallFeatureAction).
  Could not acquire the framework manipulator service.

  <p>If have actually no idea what to do now and how to fix this.</p>
