I even tried to restore the MacBook Pro to its factory setting and tried the older configuration I used to use and which worked for me.even then I got the same results and I'm wondering why? so finally I upgraded back to Big Sur when I saw gns3 2.2.17 and saw some people claiming that it works on MacBook Pro Big Sur.but that didn't work either. at first the GNS vm would show up being greyed outīut now I don't even get anything ( screen shots attached)Īnd to add some icing on the cake the gns VM get to grubĬan someone in the world plz help me before I either throw off the MacBook Pro from 4 story or throw myself off :-) how ever the day I upgraded to Mac OS Big Sur, the nightmare started. I was using gns3 with the same system even since I bought it. I've got MacBook Pro 15 with an i9 and 16Gigs of RAM 2019. I'd like to draw your attention on petty issue however that has become a nightmare for me.
