Unfortunately despite the reliability of my old Mac it’s not the only software that is having issues with its age! Thank you guys I think that you have hit the nail on the head, I have checked the points that you made spikeyxxx and all seems in order. alas there are no supported drivers beyond the ones I have installed already.
i will continue moving forward with what I can, a new machine is a ways off somewhere in the future. I doubt that the project will render correctly in this instance so 🤔.
thank you for your Help guys, very much appreciated!
