Since I moved my MacOS to Tahoe, POVRay does not work any more. I am constantly

getting the message: Cannot create render state output file. Does anyone have a

fix for this?

For testing purposes, you can give POV full access to the disk.

System settings -> Privacy & Security -> Full Disk Access, then add POVRay.

I have tried this, but still no success. I am using

POV-Ray v3,8,0-alpha.9606898.unofficial

Hi,

Is your issue solved?
I had exactly the same issue under Tahoe. It was related to the option in the Preferences panel >> Misc tab, “Redirect All Output Images To This Folder”. The path to the folder was incorrect.
The path was wrong; for some reason my output folder was located somewhere else.

It is also often related to permissions, so in any case check whether the location where the file needs to be written is available and that you have the correct permissions.

If you are not using the option in the Misc tab, check where the input file is located; the output will then be written to that same location.

I also see that you are using version 3.8.0-alpha.9606898.unofficial, which comes from the site http://megapov.inetart.net/povrayunofficial_mac/. This is a very old version.
Only use the newer versions that you can find here: https://povrayunofficial.wordpress.com
