<div><span style="font-family: 'Arial Unicode MS';">The user does not see this error running ParaView 4.x.x </span><font face="Arial Unicode MS">… so – presumably this warning message is related to OpenGL2 running on an older graphics card??? Is this something
we should be worried about in the short-term? I’m not sure how much longer this older Mac will be in service – but will we run in to issues with OpenGL2 which will preclude it from working on these older systems?</font></div>
