A Solution of sort. With some assistance from the Forum and a bit more research, I think I have an idea as to the cause of this issue and what will eventually be need for resolution.
A couple of other forum members have also encountered the same issue when using a Processing on a Mac using the new Big Sur macOS 11.1.
- Sketches with P2D and P3D renderers do not run in the IDE unless the frameRate (xx); command is included in setup.
- Those sketches do run correctly in the IDE if frameRate() is included but will not export into an application that will run.
- This occurs with both the new Apple Silicon M1 processor and the 4.2 GHz Quad-Core Intel Core i7.
So this issue appears to be the result of the new macOS 11.1 and since the current stable release of the Processing IDE for the Mac is 10.13 - those who have or plan to acquire a new Apple product that will use the OS 11.1 - may encounter this issue and hopefully a fix will appear in the 4.0 version of Processing is released.
