Brink

Brink is a free menu bar app for macOS that turns the edges of a MacBook trackpad into controls. Instead of reaching for the function keys, you slide a finger along an edge: the right edge handles volume, the left edge handles brightness, the top edge adjusts the keyboard backlight, and the bottom edge handles media playback, with a double-tap in the top-right corner to mute. It is built for people who already work on a Mac laptop or with a multitouch trackpad and want a faster, more physical way to reach the settings they change most often, without leaving the keyboard or the window they are in. Volume and brightness are among the most frequently adjusted settings on a laptop, and they normally live on keyboard keys or in Control Center. Brink approaches the same job differently by treating the trackpad as a continuous surface with four usable borders. Because the controls are slides rather than key presses, the adjustment follows your finger: you can slide up or down the right edge to raise or lower volume, or slide along the left edge to change screen brightness, and the matching macOS display appears as you go. The site sums up the idea simply: your trackpad has edges, so use them. The result is a control surface that is already under your hands, requiring no new hardware and no new habits beyond a slide. The volume control occupies the right edge. Sliding up makes the Mac louder, and the display fills in sixteen steps — the same native volume indicator your volume keys show. The brightness control occupies the left edge and reflects changes on screen with the sun icon you already know from the brightness keys. On the top edge, sliding sideways controls the keyboard backlight: left dims it, right brings it back up. Because all three use the native macOS display rather than a custom overlay, adjustments look like the ones the system already shows, which keeps the experience familiar and avoids a second set of on-screen indicators to learn. The bottom edge handles media. Swiping the bottom edge skips a track, and double-tapping the top-right corner mutes. There is also an optional double-tap on the bottom edge to play or pause, which the site notes is available if you switch it on. The menu bar panel refers to Quick Mute and a Media Strip, shown alongside haptics, sensitivity and edge width. Together these gestures mean music and other media can be controlled from the same surface as volume and brightness, without hunting for the keyboard's media keys or opening a player window. Haptic ticks give the trackpad a physical response: every step of a slide taps back under your finger, and the strength can be set to Off, Light, Medium or Strong. Fine Control lets you hold ⇧⌥ while sliding so each step splits into four for finer adjustments, and Precise Sliding makes that the default behaviour. Pointer stays put means that while you slide an edge, the cursor waits exactly where you left it, so you do not lose your place in whatever you were doing. Taken together, these details make edge slides feel precise and confirmed rather than approximate. Active Area decides where a slide can begin: anywhere on the edge, or only in the bottom ¾, half or quarter, which helps avoid accidental triggers. Swap Sides puts brightness on the right and volume on the left for people whose hands prefer that arrangement. Require Fn or ⌥ means a slide only registers while a modifier key is held, so a resting thumb never changes a thing. The menu bar panel shows live levels on the edges that set them, along with haptics, Quick Mute, the Media Strip, sensitivity and edge width, so most day-to-day settings are adjustable at a glance; settings you change once, such as swapping sides, choosing an active area, requiring a key, holding the pointer, Light or Dark appearance and opening at login, live behind them. Under the hood, Brink works by posting the same media keys your keyboard sends and by holding the pointer still while you slide, which is why macOS requires Accessibility access; the site states that nothing leaves the Mac. Only a slide that starts inside the thin edge strip counts, so taps, clicks and scrolling near the edge behave as usual, and if you still catch an edge by accident you can narrow the edge width, limit the Active Area, or require Fn or ⌥. Brink is written in Rust on Tauri by Zerowing Studios, which keeps it small and light, and builds are published on GitHub. The outcome for users is fewer reach-and-press movements: volume, brightness, keyboard light and media all become one slide or tap on a surface your hands are already on. Because the gestures drive the native macOS displays and happen without moving the cursor, the change feels like part of the system rather than a separate utility layered on top. Haptics add confirmation without looking down, and the Active Area and Require Fn or ⌥ options let people tune how sensitive the edges are to their own typing and resting habits. Concrete scenarios include adjusting volume while watching a video without leaving the trackpad, dimming the screen in a dark room, nudging the keyboard backlight up at night, skipping tracks while writing, or muting instantly with a double-tap in the top-right corner. Someone using an external multitouch trackpad, or a Magic Mouse through the Magic Mouse mode that listens along the sides of the mouse, can get the same controls on a desktop setup. Brink is free, with every feature included, no account and no trial. It requires macOS 13 Ventura or later and ships as a universal app for Apple silicon and Intel, signed and notarized by Apple. It also includes Magic Mouse support, Light and Dark appearance, a liquid-glass panel, Open at Login and updates that install themselves; the download is a disk image you drag to Applications, and from then on it updates itself. In short, Brink takes an unused surface — the border of your trackpad — and turns it into a set of native-feeling controls for the settings you adjust most, at no cost and with nothing to unlock.
