I found a black theme on the Mac similar to the PC status bar.

When browsing the page, you accidentally habitually press F5 (spline + F5)

There is such a thing

It is really like the status bar in the PC. No matter what software you are operating on, it will show the status of the operation.

But I decided to turn it off.

But what is this?

Baidu Google has been found

Okay, you have to turn to a friend who uses MAC.

In system preference settings-auxiliary functions-voiceover is this thing

Well, it's not what I use. No wonder I think it's not easy.

If you have the same second problem

Hope to get help
