Slack desktop app users can finally use the workplace chat app with the popular visual theme, dark mode. The collaboration software company announced the desktop availability of an optional dark mode feature on Thursday, September 12, via a tweet and a blog post.

According to Slack’s blog post on the matter, dark mode can be enabled on all versions of the desktop app: Mac, Windows, and Linux. The desktop availability of dark mode is in addition to the mobile platforms that already had the feature. But while the feature is now available on all platforms, Slack’s post did mention one caveat:

“…it’s worth pointing out that dark mode is device-specific: We don’t want to assume that just because you want dark mode on desktop, you’ll also want it on your phone … but you’re now free to set it on both.”

And so you’ll need to set each version of Slack you use (browser, desktop, mobile) to use dark mode individually. Just because you enable dark mode on one of them, doesn’t mean they’ll all sync up accordingly. In addition, at this time, the desktop app dark mode feature also won’t sync up with whichever mode you’re currently using on your computer. So just because your operating system dark mode settings are configured one way, that doesn’t mean the Slack app will sync with those settings. But the company did say that the ability to sync with one’s operating system will be an available feature of the app “in the near future.”

Enabling dark mode on the Slack desktop is simple. And looking at Slack’s guidelines, the method for doing so appears to be the same across desktop platforms, since the company’s directions only differentiate between “desktop” and “iOS” and “Android.”

Here’s how to enable dark mode in the Slack desktop app.

Step 1: In the top left corner, select your workspace’s name.

Step 2: From the menu that pops up, select Preferences.

Step 3: On the next screen, select Themes from the left side of the screen.

Step 4: Under Themes, select Dark.

Once you pick either Light or Dark, the app itself will switch immediately to that theme to show you a preview of it. It’s also worth noting that, in that same Themes menu, you can also choose a companion theme for your sidebar. These sidebar themes come with different color palettes.

Researchers develop a new forensic tool that can recover deleted AI chats from your phone’s memory

Did you think hitting delete on your AI chatbot conversation actually makes it disappear? Georgia Tech researchers just proved that's not entirely true. They have built a forensic tool called ORISA that can dig deleted conversations from your phone and even rebuild them into a working chatbot session you can keep talking to.

How can ORISA bring deleted AI conversations back?

Apple’s “Pro and Tell” October 28 event: Everything we expect from touchscreen MacBooks to a new iMac
Prepare for a touchscreen MacBook that costs around $3,000.
Computer, Electronics, Laptop

Touchscreen laptops have been around for years. You can get them in all sizes and shapes. Just not from Apple. For years, the Cupertino giant has treated the idea of a touchscreen MacBook the way I treat a meeting that could have been an email: with open contempt. However, Wednesday looks like the day the company could finally change its mind. 

The latest Apple invite puts the “Pro and Tell” showcase in Los Angeles at 10 a.m. PT (1 p.m. ET) on October 28, 2026. Instead of a regular live-streamed keynote, it is an invitation-only, hands-on event for a handful of press and creators (similar to what the company did for the MacBook Neo earlier this year).

Those cute delivery robots could be the new Flock surveillance menace
Dinner is served, but who asked for a biometric scan?
Food delivery robots

Two residents of Chicago have filed a lawsuit in the US over claims that robots run by Coco Robotics and Serve Robotics captured their facial and hand measurements without consent, bringing renewed attention to the food delivery robots. The cases raise a troubling question: If a robot delivers food to your door, can it also be gathering sensitive information about you?

According to a report by The Associated Press, the proposed class-action lawsuits were filed in Cook County on Oct. 9 and allege violations of Illinois’ Biometric Information Privacy Act. The complaints claim that the robots’ cameras and LiDAR sensors captured information on customers’ faces and hands as they approached the machines to pick up their orders. Both have denied the allegations.
