Concerning your boole problem, without at least a screenshot of your Objects list I would only be guessing at what issue you are having. If you could provide one, or just a simple project file of that rectangle and text set-up, it would be much easier to diagnose your issue.
In regards to the long render, while I may have your original project, several materials are missing including the fire movie. And as I said, I am not a rendering expert so I’m not the best one to ask for advice. There are others on this forum with more experience in diagnosing rendering issues, which is why I suggested starting a new post. That being said, I did run several test renders of one frame and found that my old Mac Pro (a 2012 model with the fastest processors available at that time and 64 GB of ram) was considerably slower than your computer. After approximately matching the camera angle of your sample image I got a single frame render time of over 27 minutes, so I guess you should be happy with your results. ????
In just watching the render progress it was obvious that the “Metal – Iron Cast” material was the slowest to render. Removing the Bump channel cut the render time nearly in half but caused a noticeable difference in the look of the texture. Removing AO reduced the time by about 10%. I replaced your material with a procedural material from Greyscalegorilla’s Texture Kit Pro (“Rusty Procedural”) and got a render time of just over 5 minutes for a single frame. (see image below – dbl. click on it to get an image which can be enlarged for better viewing) With this brief analysis my best suggestion would be to replace the “Metal – Iron Cast” material. Hopefully someone else will have some other suggestions, and again they will be most likely to see your question if you start a new post. And as you are probably aware, hiring a render farm is also a possibility for projects such as yours with excessively long render times.
