Download Problems / which SketchUp and Rendering Program to use?


I need a suitable program for the design of sales booths. I would like to work with SketchUp to design rooms with furniture as well as murals.
The current software on my computer is macOS Sierra 10.12.6 which brings me to my question:

SketchUp2023 as well as 2022 asks for a software update which unfortunately is not possible as the software possible for the computer is already the latest.

Will working with a 3D rendering program be possible at all? Would you have any recommendations that can be linked to Sketch Up in a good and user-friendly way?
