 **First launch:** macOS will block the app because it's not signed with an Apple Developer certificate. To open it:

 Once running, ResolveZoom appears as an icon in the menu bar. Open DaVinci Resolve, place it in focus, and start pinching on your trackpad — the timeline will zoom in and out.
 
 **Menu bar status:**
+
 - 🟢 **DaVinci Resolve active** — gestures are being intercepted
 - ⚪ **Waiting for Resolve…** — Resolve is not in focus
 - 🔴 **No accessibility permission** — grant access in System Settings
 
 **Preferences** (click the menu bar icon → Preferences…):
+
 - **Zoom Sensitivity** — controls how fast the timeline zooms. Default is 800; increase for faster zoom, decrease for finer control
 - **Invert zoom direction** — reverses the zoom direction if it feels unnatural
 - **Launch at Login** — toggle autostart with macOS
 
+ResolveZoom checks Resolve's active page once per second while Resolve is focused. The Accessibility scan runs on a background utility queue with a 50 ms IPC timeout, so an unresponsive Resolve UI cannot interrupt pinch handling.

 ## Known Issues

 **Why:** ResolveZoom works by intercepting trackpad pinch gestures and converting them into synthetic Alt+Scroll events that Resolve understands as zoom commands. Resolve's "Zoom Around Mouse Pointer" feature works correctly with native hardware scroll events, but our synthetic events take a different internal code path in Resolve that always defaults to playhead-centered zoom.
 
 Several approaches were investigated to work around this limitation:
+
 - Marking synthetic events as "continuous" (trackpad-style) using private CGEvent fields
 - Sending gesture phase information alongside the scroll event
 - Injecting synthetic magnify events (type 29) directly — Resolve ignores these entirely
