Rimline is not open for download yet.
Join the waitlist and you get one email the day it is. It runs on macOS 13 and later, with a 3 day free trial.
We keep your address, the date and the page you signed up from, and nothing else. How to be removed.
The first launch.
Rimline is signed, but not yet notarized by Apple, so macOS asks you to confirm it once. It is a few clicks and it only happens the first time.
Drag to Applications
Open the disk image and drag Rimline into the Applications folder.
Open it, then allow it
Open Rimline. macOS says it cannot verify it. Close the warning, then:
On macOS 15 and later, scroll down in Privacy & Security until you see the message about Rimline.
Prefer Terminal?
xattr -dr com.apple.quarantine /Applications/Rimline.appAllow Accessibility
Rimline asks for Accessibility in System Settings, Privacy & Security. It needs it to read touches on the trackpad and to move windows. The setup window notices when you grant it and walks you through your first slide.
Why not notarized yet?
Notarization needs an Apple Developer ID. Until then, Rimline is signed with a stable certificate so that macOS keeps the Accessibility permission across updates, and each update is signed with its own key and checked before it installs. When notarization lands, the extra click goes away and this page will say so.
Why is it not in the Mac App Store?
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.
Requirements
- macOS 13 Ventura or later.
- A MacBook with a built-in trackpad. A separate Magic Trackpad with its own layout is not supported yet.
- Accessibility permission.
Moving from an earlier build that carried the name Edgeline? The first launch copies your settings over. macOS ties the Accessibility permission and Open at login to the app identifier, so Rimline asks for those once more.
