+## macOS stuck-cursor freeze
+
+A `MouselookStop()` issued while the window is backgrounded (a watched frame auto-unlocks Mouse Look during an alt-tab, e.g. bags/LFG) leaves the OS mouse capture stuck — frozen cursor/camera on return while `IsMouselooking()` lies. There is no window-focus event and the background keeps rendering, so it can't be detected from `OnUpdate`. Recovery is the manual `Combat Mode - Reset Mouse Look` keybind (`CombatMode_ResetMouseLook`, `Core/FreeLook/FreeLookController.lua`): re-grab + release through `CM.LockFreeLook` / `CM.UnlockFreeLook` (keeps UI in sync). The config keybind (`UI/Options/Tabs/TabGeneral.lua`) is shown macOS-only via `IsMacClient()`.
