Show HN: Open in Cursor" Finder Extension for macOS (github.com)

Open in Cursor is a small macOS Finder toolbar app (Show HN) that opens the current Finder folder directly in Cursor (the code editor/IDE), streamlining the jump from file browsing to coding. You can install it via Homebrew (brew tap inem/open-in-cursor; brew install --cask open-in-cursor), download a pre-built release or the latest GitHub Actions artifact, or build from source (git clone inem/OpenInCursor; make && make install or open the Xcode project). After moving the app to /Applications and adding it to the Finder toolbar (hold ⌘ while dragging), clicking the toolbar icon opens the active folder in Cursor. First-run requires right-click → Open to satisfy macOS Gatekeeper and may prompt to allow the app in System Settings. This is significant for AI/ML engineers and devs who use Cursor because it removes friction between file-system navigation and an AI-enabled coding environment—speeding context switches and supporting tight dev-test cycles. Technical notes: recommended Gatekeeper workflow is right-click → Open; alternatively use sudo xattr -rd com.apple.quarantine "/path/to/Open in Cursor.app" to clear quarantine. The project is open-source on GitHub and supports building via make or Xcode; make install places the app in /Applications.
