I’m adding to this thread as this seems related to Apple’s tightening security. I’m not able to write to disk from Cabbage, i.e. using things like fout, pvsfwrite. This is on OS 12.6. The same code works on OS 10.13. Also, the same opcodes work fine using Csound without Cabbage on 12.6.
The error is produced whether the file is pre-exisiting or not.
