I got a new place to sit at work and sometimes the sun light is too much.
Luckily I found a brief blog post on how to switch to and from dark mode from the command line.
osascript -e 'tell app "System Events" to tell appearance preferences to set dark mode to not dark mode'The setting is a boolean so it works both ways, as a light switch practically.
This is one those small things, where open menus a click around and when you finally get around to doing something about, you do not understand why you did not do it earlier - the dishwasher acquisition syndrome.
