Using a screensaver as a desktop wallpaper? I've looked around a lot for a way to use one of the screensavers as the wallpaper for my desktop. I found a few options but all of them didn't seem to work on macOS Catalina. The way I tried to attempt this was by using the following code.
/System/Library/CoreServices/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -background &amp;
All this does is launch the screensaver, instead of making it my wallpaper. Any way that this could be done on Catalina?
If you just want a still image of a certain frame in the screensaver you can do a screenshot of the screensaver at the right time and then use the sceenshot as your desktop.
if you want the running screenshot to be your desktop there was a similar question asked and the answer is given here for High Sierra and that may apply to Catalina.
