I've been delving into Terminal after my iMac failed and I was able to save it through Terminal commands in a way that GUI Disk Utility wasn't able to.

It got me interested in what's happening behind the scenes. Is macOS not constantly executing commands in the background? Is there an app or a Terminal command that would expose them? I'd love to have a viewer showing what macOS is doing, kind of like The Matrix.

I know that you can go into Verbose mode to watch the code being executed when the Mac is booting up, but what about after it boots?

Is there an app that does this or a Terminal command that exposes it?
