Thanks in advance for this forum post with many valuable tips!
Unfortunately, I have so many different scenarios where my in-process scenes crash that I can't even reproduce them at this time.
Sometimes I have to open Cinema 2-3 times in a row, another time Cinema says goodbye with a click on "Restart new render" in Octane and another time when simply changing textures from GSG Plus library.
This has been going on for 2 weeks now, forcing me to return to my old Windows workstation with GTX cards to finish pending projects

For now, I have to say that it was a wrong decision to switch to Mac M2 with C4D and Octane.
Possibly it has something to do with the fact that my scenes were created on Windows (except for the program versions used, the same setup).
I still hope that my setup will run with future releases.
As soon as I have more knowledge and can reproduce crashes, I will report it here.
BR, Chris
