A new feature of macOS Mojave is Dark Mode. This favors light text on a dark background instead of dark text on a light background in the system and standard apps. You can see the change in the menu bar, app toolbars and sidebars, and even the backgrounds of apps like Contacts, Calendar, Reminders, Notes, Mail and Maps. Not all apps will change, especially third-party apps. Document content and images will not change either, as they keep using the true color specified in the document. You can also change the accent color used in standard interface elements throughout macOS.
Bill: I doubt it. LCD screens are "lit" whether it is white or black pixels showing. Dark Mode is not meant for energy savings. But I suppose if you can turn your screen brightness down because of Dark Mode more than in normal mode, then you may actually get some savings.

Dark Mode on my iMac 2017 sucks processor power. The Mac is slower to respond. I do not use it.

Hi Gary! I stumbled across this tiny, neat (and free) little app called "Night Owl", which sits in the menu bar, and is a much quicker and more convenient way of turning Dark Mode on or off! It might interest you!? I've been using it since installing Mojave last week, no problems! Best regards, Ian. The developerĀ“s site: https://nightowl.kramser.xyz

I will admit, I think Mojave might have a bit of a learning curve built in. Switched back to Dark Mode earlier today and as the day went on, it (DM) or I seems to process better. No explanation but windows and apps are closing again at light speed. Sorry for the blast earlier.
joe: It sounds like the slowness was unrelated. Perhaps macOS was still cleaning things up and indexing files after the upgrade.

Mojave was super slow until I did a clean install, now works great. I am curious if dark mode saves energy. Would be fun to know how much energy Apple saved the world through this update.
josh: I don't see how Dark Mode will save any energy. Perhaps if you also turn down your screen brightness, but you can do that with Dark Mode off too.
Will battery life be better in dark mode? I am assuming battery power is saved by not having to illuminate who blocks of the screen.
