Thank you for your opinions guys!
Blackheifer-
according to the developers, exactly as you write, my mac is between low and medium settings. that is, in theory, at a very low level, the game should be smooth and work flawlessly. unfortunately it is not. it turns out that there is a lack of optimization and hope that Larian will deliver what they promise with the release of the full version and a possible patch.
I had the drive replaced with an SSD, I have the box somewhere but cant find now. For sure it is a fast drive. Minimum +100% faster than if I were to use the HDD mounted in imacs from 2017 ... - I think this clue is not the point.
