LinkLane Helper

The Mac App Store version of LinkLane runs in Apple's App Sandbox. The sandbox does not allow apps to launch other apps with options – but that is exactly how Google Chrome and Microsoft Edge select a profile, and Dia needs automation for it. LinkLane Helper is a small, free companion app that does this one job for LinkLane.

You only need it for fixed profiles in Chrome, Edge or Dia. Everything else – rules, source apps, Safari, Firefox, Chrome/Edge/Dia with “Browser decides” – works without it. The directly distributed version of LinkLane does not need the helper either.

Installation

1. Download and unzip the file.
2. Move “LinkLane Helper” to the Applications folder.
3. In LinkLane, check Browsers → LinkLane Helper: it should show “Installed”.

The helper has no window and starts only when LinkLane needs it; it quits after a minute without requests. For a fixed Dia profile, macOS asks once whether LinkLane Helper may control Dia.

Security

• It only accepts requests from apps signed as LinkLane by the same developer and ignores everything else.
• It only opens HTTP/HTTPS links and local HTML files in Chrome, Edge or Dia with a valid profile and never accepts arbitrary launch options.
• It makes no network connections and stores no data.

Uninstall

Quit LinkLane and move “LinkLane Helper” from Applications to the Trash.
