Dark mode, but make it dramatic
Show HN: Zen Mode – a global focus mode for macOS
Mac users are swooning over a shortcut that blacks out every distraction
TLDR: Zen Mode is a Mac shortcut that throws a black curtain over everything except the window you’re using, turning your desktop into a one-window spotlight. Commenters loved the calm, but immediately argued over whether real focus means one app at a time — or several windows in a carefully managed mess.
A tiny new Mac tool called Zen Mode has landed on Show HN, and the real action is in the reactions. The pitch is deliciously simple: hit one shortcut, and your current window slides into the center while the rest of your screen goes dark — wallpaper, Dock, top bar, the whole chaotic circus. It’s basically a personal spotlight for your work, and commenters instantly split into two camps: “finally, peace” versus “wait, why doesn’t the Mac already do this?”
The author popped in to say this was built because nothing else quite matched the vision. That kicked off the classic internet drama of people comparing it to every existing focus tool under the sun. Some were impressed by how dramatic the blackout effect is, while others responded with a very online version of a shrug: if the point is to focus, why only one window? One of the strongest reactions came from a multitasking crowd member begging for a version that could spotlight multiple apps at once, because apparently some people’s “zen” still includes controlled chaos.
And then came the funniest vibe check of the thread: a longtime Linux user basically asking, “hold on… this isn’t already normal on Macs?” That comment has big "I left the group chat in 2013 and came back confused" energy. So yes, the tool is neat — but the comments turned it into a referendum on how distracting modern desktops have become, and whether true focus means one perfect window or a whole carefully staged command center.
Key Points
- •Zen Mode is a macOS focus tool implemented as a Hammerspoon script that works with any focused app window.
- •When activated, it centers the active window, expands it to full screen height, and blacks out surrounding interface elements including the Menu Bar and Dock.
- •The tool uses a single hotkey, Option + Cmd + Z, to enter or exit the mode, and Esc also exits while the mode is active.
- •It preserves interactivity of the active window by placing a full-screen CoreGraphics overlay above the desktop and cutting out a transparent rounded opening where the window sits.
- •Setup requires macOS, Hammerspoon, Accessibility permissions, and adding the provided Lua configuration to the user's Hammerspoon init file.
