switchdarkmode

Install

A Launchd plist with an Applescript to switch on schedule between Dark Mode and Light Mode on macOS Mojave. The default plist switches at 7:15am and 9:00pm. This no frills script has no external dependencies and can be installed on macOS using the below snippet in the Terminal.

curl -o ~/Library/LaunchAgents/local.switchdarkmode.plist https://raw.githubusercontent.com/superman-lopez/switchdarkmode/master/local.switchdarkmode.plist && launchctl load ~/Library/LaunchAgents/local.switchdarkmode.plist

That's all that is needed for it to work!

Optional steps

If you are keen to test, it's possible to invoke the command immediately rather than wait for the scheduled run:

launchctl start local.switchdarkmode

The schedule can be easily adjusted by editing the plist. For example:

nano ~/Library/LaunchAgents/local.switchdarkmode.plist

Change the timing in the following section:

	<array>
		<dict>
			<key>Hour</key>
			<integer>21</integer>
			<key>Minute</key>
			<integer>00</integer>
		</dict>
		<dict>
			<key>Hour</key>
			<integer>7</integer>
			<key>Minute</key>
			<integer>15</integer>
		</dict>
	</array>

After that unload and reload the plist for immediate effect:

launchctl unload ~/Library/LaunchAgents/local.switchdarkmode.plist && launchctl load ~/Library/LaunchAgents/local.switchdarkmode.plist

Uninstall

To uninstall everything simply run:

launchctl unload ~/Library/LaunchAgents/local.switchdarkmode.plist && rm ~/Library/LaunchAgents/local.switchdarkmode.plist
