Much to the relief of night owls everywhere, Slack has finally released a dark mode for macOS, Windows, and Linux. Here's how to banish the white background, and head over to the dark.
If you're one of the people who have been holding their breath for a dark mode in Slack, it's time for you to breathe a little easier. Slack's HQ team has announced that dark mode has finally made an appearance on the desktop versions of the application.
If you use Slack on your Mac, you can try out dark mode today.

Like in Slack’s mobile app, dark mode for desktop is a deep shade of charcoal rather than an all-out black. Gizmodo staffers agreed the theme is welcome, though the font doesn’t have the same. Sep 12, 2019 Look out for an update for Slack’s macOS app today and/or you may need relaunch the app to see the new dark themes. To change themes, head to Slack’s Preferences Sidebar Theme.
Slack has noted that you must be updated to version 4.0, and that you may need to restart the app a few times before the effects take place. All the old slack sidebar themes remain as well, but have been updated to work better with the new dark mode.
Dark mode is especially useful for those who work in low light or late at night. It is also beneficial to users with certain types of visual impairments.

In March of 2019, Slack released a dark mode for their iOS and Android apps, but tweeted 'Dark mode isn't available on our desktop app right now, but we're working on it. Stay tuned for a brighter, darker future.'
Six months later, Slack has finally given users the option to opt in to dark mode, should they want it. Responses from the community trend overwhelmingly positive.

SO! Finally! Here we have it: For those who need it, who want it, who have asked for it or who could just use it occasionally — dark mode is now available on the desktop app as well as mobile, for everyone. Read more: https://t.co/2KXjYlDWkUpic.twitter.com/OKZ0NfqybK
