If you opened Twitter in your desktop browser today and something seemed different in the website's appearance, you're not wrong. In a change to its usual dark blue tint, Twitter is switching its desktop dark theme to a pure black.

Follow @MacRumors on Twitter

Twitter has told The Verge that the change is part of an update that's rolling out to make the Twitter website respond to the light and dark mode settings of your operating system (although this didn't work when we tested it).

If your Twitter experience switched from dark mode to light overnight, however, that's down to a bug, according to the company. This may have happened to you if you had Twitter set to Dim or Lights Out mode but your OS was set to light mode.


If you miss the old dark blue, you can bring it back using Twitter's Dim display setting. You can find Twitter's desktop display options by clicking More in the left-hand menu and selecting Display. You'll see radio buttons for Default, Dim, and Lights Out modes, as well as options to change the accent color from the default blue. Twitter should remember your color and background settings after you've selected them.

Before the update it changed with the system settings, now I get blinded every night until I manually change it.

The switching spontaneously to light mode is a long-standing bug, been around for at least a few months. Usually happens when you reload the page.

I just wish Apple and/or Twitter would fix the "Significant memory" warning that's always appearing on the site. Even reloading doesn't make it go away half the time, and often you dismiss it and it comes right back.

The worst thing is that it's not even using that much memory and is running fine; the warning is annoying as hell.

Why not just use the Mac app?
It's buggy as hell.

So far I've experienced:

- Weird text-typing behavior when composing tweets (this has gotten better with Big Sur but still happens occasionally)
- Low resolution images when dragging photos from the Photos app to tweet them (website posts them full resolution).
- Partially hangs when you try to add an image from a tweet to Photos. (You can't close the image anymore until you restart the app, image never gets added to Photos)
- General UI glitchiness here and there. Sometimes scrolling the timeline gets wonky.

Overall it's a lousy experience compared to the website. I've reported some bugs but nobody seems to be listening.
