Hi @lubos. Thank you for reply.
Indeed I have a MacBook Pro machine with the latest OS Sierra 10.12.4.
As graphic card I have the GTX 750m that's soldered on my Mac and also I have a GTX 1060 eGPU. So indeed I think that Apple don't offer support for OpenGL 4.5, maybe they want to promote theirs own Metal s**t, or I'm thinking that can be also a problem in nVidia side because I'm running the newest beta drivers that has just released some days ago, the first drivers that are allowing me to run the GTX1060.
@Chris.k Thank you for advices, I tried both of them, still the same.
