[Gate-users] unable to activate the viewer to see the geometry

[Cheng Xu]

Hello,

I have not been using GATE for almost a year, and a few days ago, when I try to implement a code, the following messages appear, which I have not seen before, does anyone know what the problem is? I guess it is the OpenGL problem , but not really sure, and do not know how to fix it. I am running GATE on macbook pro with osx 10.9.5.

Thanks and best regards,
Cheng
