Questions, answered.

A Mac menu bar app that turns the edges and corners of your MacBook trackpad into controls. Slide an edge for volume or brightness, tap or hold a corner for a shortcut, and snap windows with a slide.

Download the disk image, drag Rimline into Applications, and open it once. Allow Accessibility when it asks, and the setup window carries on by itself. Homebrew works too.

Notarization needs an Apple Developer ID, which Rimline does not have yet. It is signed with a stable certificate, and each update is signed with its own key and checked before it installs. On the first launch macOS says it cannot verify the app: close the warning, then open System Settings, Privacy & Security, and press Open Anyway. You do it once.

Reading the trackpad, the keyboard light and the display brightness goes through system frameworks that Apple does not publish and that sandboxed apps cannot use. Every call is guarded, so if a macOS update moves one, that feature turns off instead of crashing the app.

Turn on the update check in General, then Updates. Rimline asks GitHub once a day, shows what is new, and installs only when you press Install Update. With Homebrew, brew upgrade --cask rimline also works: pick one way, not both.

Quit Rimline and drag it from Applications to the Trash. With Homebrew, brew uninstall --zap --cask rimline also removes its settings.

macOS 13 Ventura or later, on Apple silicon and on Intel. Rimline was developed and tested on Apple silicon.

Rimline is made for the built-in trackpad of a MacBook. On a Mac with no built-in trackpad it listens to a connected one, but that has not been tested.

Not yet. A separate Magic Trackpad with its own layout, one layout per device, is planned and not supported today.

Rimline can pause itself while the app in front is full screen, which is off until you switch it on in General, Protection. It also has actions for Full screen and for turning Stage Manager on and off.

A window can move to the next or previous display and keep its place and size relative to the screen. Brightness changes the display under the pointer, and a scene can switch on by itself while an external display is connected.

There is no account, no sign-in, no analytics and no crash reporting inside the app. Your touches, layouts, scenes, workflows and settings stay on your Mac. Rimline does not read your screen contents or what you type. It reaches the network only to activate and check a license with Polar, and to look for updates if you turn that on.

Accessibility, so it can read touches on the trackpad and move and resize windows. Two actions ask for more the first time you use them: dark mode asks to control System Events, and screenshots use the macOS shortcuts.

Your touches never leave your Mac. The app reaches the network for two things. It contacts Polar to activate a license and to quietly re-check it now and then, sending the license key and a name for your Mac. And it can look for updates, which is off until you turn it on in General: then it asks GitHub once a day whether a newer version exists. An update is accepted only if its signature matches the key built into the app.

A plain report on your clipboard: the version and build, macOS, the Mac model, whether Accessibility is granted, where Rimline lives, the finish, which gestures and guards are on, and counts of scenes, app layouts, saved presets and places in use. It names no app, file, shortcut or layout, and nothing is sent anywhere. Send feedback opens a draft in your browser that you read before you submit it.

A 3 day free trial with every feature on and no card. Then $9 once, with all updates.

No. It is one payment, and every update is included.

The trial runs 3 days from your first launch, with every feature on and no card. After that Rimline will ask for a license to keep going. Your layouts, scenes and settings stay on your Mac.

Two Macs per key. You will be able to deactivate one from the app or from the Polar portal to move it. The license is checked when you activate and quietly again when you are online, and it keeps working offline for 30 days after the last good check.

Yes. 14 days, no questions asked. Polar is the merchant of record and handles payment, tax and VAT.

Slide an edge for volume, brightness, microphone level or the keyboard light. Tap, double tap or hold a corner or the middle of an edge for media, sound, window, space and system actions, to open an app, a link or a file, press keys, type text or run a command. Workflows chain several actions into one.

A scene is a layout that turns on while you hold a key, with a shortcut, or by itself for an app, headphones, an external display, a time of day or the power source. The on-screen display names a scene when it comes on or goes off.

Touches are ignored while you type and for a short moment after, so a palm on the trackpad does not fire anything. In General, Protection, a guard time slider sets that moment from 0.2 to 1.5 seconds.

The Multi-finger page reads your macOS trackpad settings and marks the gestures where macOS does the same thing, and the editor shows a Heads up when two of your own gestures collide. A hold is the clean choice, or turn the system gesture off in System Settings, Trackpad.

Undo the last change is always one click away in General, Backup and presets, and Reset all options can be undone too. After you apply a preset on the Presets page, a bar offers Undo to put back the setup from before. You can also save your layout as a preset of your own and come back to it.

A saved copy of your setup with the parts you choose: layout, gestures, apps, scenes, workflows, feel and timing, look and feedback, and your own presets. Double-click one, or drop it on the app, to see what is inside and put parts back. Commands inside a file from someone else are counted and kept out unless you allow them.

Put the Gesture cheat sheet system action on any gesture, or open rimline://action/cheatSheet. It draws a card shaped like your trackpad with what each place does right now, for the app in front and the scene in force, and it closes on a click, a key, or after 12 seconds.

A crowded menu bar, or a manager such as Ice or Bartender, can push a new icon out of sight. Rimline always opens from its Dock icon, and General shows Icon hidden with a Bring it back button.

Check that Accessibility is granted in System Settings, Privacy & Security; in General, the Accessibility tile says whether it is. If the menu bar icon is dimmed, Rimline is paused, or auto-paused because a game is in front. Test and tune on the Trackpad tab shows what the trackpad reports.

If macOS does the same thing, the Multi-finger page marks the gesture, and a hold is the clean choice. For an accidental one, raise the guard time under Protection in General, turn on Require Fn or Option, or turn Rimline off in the app where it happens. Test and tune lets you resize the corners and the strips.

If you ran Rimline before it had its own identifier (it was net.sabiss.edgeline), the first launch copies your settings over. macOS ties Accessibility and Open at login to the identifier, so Rimline asks for both once more.

In the app, open General, then Help and feedback. Copy diagnostics puts a plain report on your clipboard, and Send feedback opens a new issue with the questions and the report filled in. You read it before you submit it. You can also open an issue yourself on GitHub.
