Often I’m working in quiet places like libraries or shared office spaces. This led to the desire to have my laptop muted everytime I open it. And it should be muted not with 2 seconds delay but instant, no matter the load.
Years ago I created a very small piece of software to mute macOS everytime it is going into sleep mode or gets shutdown. It works pretty well for me and since people kept asking about it, I published it to Github.
