macOS Mojave Theme (Dark mode) switcher

[cama900]

Hey everybody, I've been testing out macOS Mojave + Dark mode the past few days and wanted to be able to toggle between the light theme and dark theme using alfred. So I made a simple workflow for it.

It's probably not useful to most of you yet (as Mojave it's still on dev beta 1) but i'll be making sure it stays working as there are more updates

Actually it looks like the scripting commands are unchanged from Yosemite:

Awesome! I hadn't seen that one before. While the AppleScript in the theme does work to toggle between light and dark mode, running the workflow doesn't toggle it for me. I'll have to try and figure out why

Works great, but also changes my Alfred theme every time as well back to one of Alfred's default themes. How do I make it stop doing that?

[cama900]

Yep, you can open the workflow and edit the Run Script element. Right at the top there's 2 lines that say

var alfredLightTheme = "Alfred"
var alfredDarkTheme = "Alfred Dark"

You can change them to whatever theme you want for when the mac is in light/dark mode. Just put them both to the same theme name if you want it to always be the same.

 

I may be adding support for other apps and I'll make the process better if I do.

This is the script completely without the Alfred theme switching part:

 

function run(args) {
	args = args ? args : []
	var systemEvents = Application("System Events")
	
	if (args && args == 'dark') {
		systemEvents.appearancePreferences.darkMode = true
	} else if (args && args == 'light') {
		systemEvents.appearancePreferences.darkMode = false
	} else {
		systemEvents.appearancePreferences.darkMode = !systemEvents.appearancePreferences.darkMode()
	}
}

I updated the app to make it easier to choose wether or not to toggle the Alfred theme, as well as support for toggling the theme of the Sourcetree app.

Hi cama900,

Thanks for sharing the WF, just what I was thinking about.

Do you have an idea where to get the sunrise / sunset trigger from?

Would be interesting to add an automatic trigger to your WF

@endrus Here's a script that can toggle Alfred's theme at sunrise & sunset. You can adjust the AppleScript in it to call this workflow.

I would love this workflow. But it does not work for me. When I "toggle" or go on "dark" nothing happens. Any idea why?

I'm trying to extend this workflow to change the wallpaper with it. Does anyone know how to apply the new desktop picture to all spaces?

 

Atm my script looks like

 

set theQuery to argv
	set thePath to "~/Dropbox/Pictures/" & theQuery & ".png"

	tell application "System Events"
		tell every desktop
			set picture to POSIX file thePath
		end tell
	end tell
	do shell script "killall Dock"
end run
