Empty desktop on MacOS through ElectronJS

[tonnyorg]

Describe the bug
Calling this library from Electron ends up taking screenshots of the empty desktop: it pictures the wallpaper and the top bar, but none of the opened windows show up.

To Reproduce

const screenshot = require('screenshot-desktop')
screenshot.listDisplays().then((displays) => {
      console.log(displays);
      screenshot({ screen: displays[displays.length - 1].id, filename: '/tmp/demo' + displays[displays.length - 1].id + '.png' })
        .then((img) => {
          console.log(img);
        });
    });

Expected behavior
Supposedly it should take a picture of the actual screen (with all the windows opened and so).

Environment (please complete the following information):

• OS: MacOS Catalina 10.15
• Engine: Electron
• Version: 7.1.9

That's odd, I wonder if it's some sort of security restiction. Under the hood we use the screencapture tool on OSX. Could you try running the following and see if you get the same result?

$ screencapture -x -t jpg out.jpg

@bencevans I know what the problem is now, you have to enable "Screen Recording" for the app (your ide, your console, or wherever you run the screencapture from).

To fix it: System Preferences -> Securtity & Privacy -> Privacy (tab) -> Screen Recording -> and select the app(s) to allow it.

I am too getting the only desktop in the below mac version if there is any open program it still only takes a screenshot of the desktop in another mac version it is running perfectly I have allowed screen recording still it takes pictures of desktop only

@sankyn1 Might need to allow screen recording for a different process. Depending on how you're running it. E.g. If you're running your app from an IDE you may need to allow the IDE the screen recording permission.
