“If the Chrome download bar on your Mac is staying open, you can try closing it with Alt+Shift+H or using the "Hide Download Bar" Chrome extension.”
There is no “alt” key on a mac. There is no extension for chrome called “hide download bar”— this isn’t even a remarkably bad AI result it is just how it is now.
I assume people who don’t use computers often don’t notice how bad this is? Maybe they just think they can’t make their computer work because they are bad at computers?
