title: Getting Warnings in Unity 5.5 Editor
body: <p>In Unity5.5 editor I am getting several warnings of which two include:</p>
  
  <p><a href="https://i.stack.imgur.com/I1WOc.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/I1WOc.png" alt="enter image description here"></a></p>
  
  <pre><code>Platform LinuxStandaloneSupport has only one supported graphics device type (OpenGL Core)
  Platform MacStandaloneSupport does not support graphics device type OpenGL
  </code></pre>
  
  <p>How would I go about solving these errors, as by reading them I have noticed I have to change my graphics device type perhaps but first of all I am not sure if this is the solution and second of all even if it would be I am not entirely sure how I would do so.</p>
  
  <p>Edit:
  I am not sure if this is related and able to help you guys out, but I am also receiving errors like:</p>
  
  <p>Assets/Editor/ImageEffects/ColorCorrectionLookupEditor.cs(54,41): warning CS0618: <code>UnityEditor.TextureImporter.textureFormat' is obsolete:</code>textureFormat is not longer accessible at the TextureImporter level. For old 'simple' formats use the textureCompression property for the equivalent automatic choice (Uncompressed for TrueColor, Compressed and HQCommpressed for 16 bits). For platform specific formats use the [[PlatformTextureSettings]] API. Using this setter will setup various parameters to match the new automatic system as well possible. Getter will return the last value set.'</p>
