Running embedding-matplotlib-example on macOS

[luliCloud]

I wanted to express my admiration for the MetaCall project; it's truly remarkable. Recently, I had the opportunity to download and implement it on my macOS laptop, during which I encountered several issues. It appears that the current documentation primarily addresses the Linux environment, with no specific considerations for macOS. Through some investigation, I managed to resolve these issues on my local machine. I would like to share these insights with you. Would you be interested in a detailed report on the matter? I am prepared to outline the problems, suggest solutions, or even submit a Pull Request to address them. Please let me know how I can assist further.
