Precise switching, windows stay put

Switching is what you do most, so it has to work every single time. On the Tungsten Edge taskbar, each window holds exactly one place. Click it, and that is the window you get.

Light, lean, and at one with macOS

A great Dock should feel like part of the system: shaped by the design language of macOS, and all but invisible while it runs. Tungsten Edge borrows window management from Windows, and nothing more.

2 Dual-Source Arbitration Two sources, one verdict
Accessibility and window-server data, sampled side by side. Only Accessibility can add a window; the window server only confirms or vetoes.
5 Five-Gate Release Five checks before removal
A window is released only when all five conditions hold. Fail-safe: when in doubt, keep it.

No fuzzy merging by title or position. Missing is not closed; take over only on a unique match.

Frequently asked questions

Is Tungsten Edge free?

Currently free. The release version will be a one-time purchase with no subscription; founding users who confirm their email before launch keep it free forever. Source code is public on GitHub.

How is it different from uBar or DockDoor?

uBar is a mature paid taskbar; DockDoor adds window previews to the Dock. Tungsten Edge is an open-source, full Dock replacement, and most of the work goes into two things. First, precise switching: windows keep their place on the bar however often you switch or minimize, a tabbed Finder window still counts as one window, and 375 of its 1,198 unit tests cover window identification and switching. Second, light and lean: it takes only window management from Windows — no Start menu, system tray or clock — follows macOS in look and motion with native Liquid Glass on macOS 26 and later, and idles under 0.7% CPU.

Why does it need Accessibility permission?

The taskbar needs it to read the window list and to switch and minimize windows, which is what macOS requires of any window-management tool. Ordinary input is not recorded, modified or uploaded, and the app never collects anything over the network.

Which Macs and macOS versions are supported?

macOS 12 (Monterey) or later, universal for Apple silicon and Intel. The installer is signed and notarized by Apple, so it opens with a plain double-click.

Will it slow my Mac down?

No. Tungsten Edge is written in native Swift rather than wrapped in Electron. Idle CPU use stays under 0.7%, and memory sits around 100 MB after hours of use.

How do I install it? Is there a Homebrew cask?

Download the dmg from this site and drag it into Applications. Homebrew works too: brew install --cask tungsten-edge — Tungsten Edge is in the official Homebrew cask registry.

How do I hide the macOS Dock?

You do not need System Settings: click the Tungsten Edge icon in the menu bar, and under The Dock section header drag the slider to Never Wake, then press the confirm row that appears — the Dock is then fully out of the way and will not pop up when the pointer reaches the bottom edge. (Every write restarts the Dock and flashes the screen once, which is why nothing is applied until you confirm.) The first-run guide sets the same thing with one click, and ⌥⌘D brings the Dock back whenever you need it.

How do I uninstall it?

If you changed the Dock's wake delay, set it back to Always Visible in the status menu first. Then quit Tungsten Edge, drag the app from Applications to the Trash, and remove its entry under System Settings > Privacy & Security > Accessibility.
