title: QOpenGLWidget: Failed to create context
body: <p>I am a new MacOS user. I have a problem when I ssh into a remote computer using X11 forwarding. I am trying to view 3D Slicer from my remote computer. 3D Slicer loads correctly, but I am unable to visualize anything. However, if I hover the mouse I can see the menu options. But I am unable to see any data that I load. 
  On the terminal, I see QOpenGLWidget: Failed to create context and 
  composeAndFlush: QOpenGLContext creation failed
  composeAndFlush: makeCurrent() failed</p>
  
  <p>I tried updating my MacOS in the hope that the driver would also update. But that did not help either.</p>
  
  <p>I am using a Mac mini (Late 2014), macOS Catalina with a 2.6 GHz Dual-Core Intel Core i5 processor and Intel Iris Graphics.</p>
