Mac OS - Second Screen

[paurosello]

Only changes background on main screen

I dont know if this applies in this repository. We are using a third party golang library: https://github.com/reujab/wallpaper
So, we have to investigate if we can use this library with some options to solve this issue, or open a new issue to @reujab: https://github.com/reujab/wallpaper

@paurosello The library uses AppleScript to set the wallpaper, but I don't have instant access to a Mac, so can you run the following command in a terminal and tell me if it sets the background of every desktop?

osascript -e 'tell application "System Events" to tell every desktop to set picture to POSIX file "/Library/Desktop Pictures/Desert.jpg"

[paurosello]

It works after accepting the following popup in Mojave :)

[reujab]

If you replace System Events with Finder, does it display the same popup?

[paurosello]

Tried this and other solution like:

tell application "Finder"
	set theDesktops to a reference to every desktop
	set picture of desktop of the theDesktops to POSIX file "/Library/Desktop Pictures/Desert 3.jpg"
end tell

with no luck, cannot seem to do it with finder for both screens, only with Sytem Events

[reujab]

The popup is undesirable, so I will not make System Events the default behavior of my library.

@angelbarrera92 What behavior do you want? Do you want your application to always display this popup, regardless of whether the user has multiple desktops?

EDIT: pinged wrong person

I did not see this message before, sorry.

We can assume click on a modal button if we can put hoff in all MacOS screens.

Thanks @reujab
