I recently purchased your electronic simulator program, Crumb, for my Mac running on the Mojave operating system. While I am able to build circuits and load the demos, I am experiencing issues with their functionality.
The circuits do not work at all, and the demos also. I have followed the instructions provided but have been unable to resolve the problem on my own.
I kindly request your assistance in resolving these issues. I would appreciate any guidance or support you can provide to ensure that the circuits and demos function correctly on my system.
Thank you for your attention to this matter. I look forward to your prompt response and a resolution to the problem.
