Overview
QuickRecorder is a lightweight, high-performance macOS screen recorder engineered directly on top of Apple's ScreenCaptureKit API. Built natively in SwiftUI, it supports multi-monitor capture, window/application isolation, iOS device recording, driver-free system audio loopback, real-time Presenter Overlay, and HEVC with Alpha transparency.
How It Works
QuickRecorder operates through structured, deterministic execution stages:
ScreenCaptureKit Hardware Pipeline: Captures crisp 4K/60fps display, window, application, or connected iOS device feeds via Apple's native ScreenCaptureKit framework.
Driver-Free Loopback Audio Capture: Records system and per-application internal audio streams natively without installing virtual audio kernel extensions.
Presenter Overlay & Alpha Video: Composites live camera feeds seamlessly on macOS 14+ and supports HEVC with Alpha transparency for nonlinear editors.
Interactive Cursor & Zoom Aids: Enhances recordings with real-time mouse highlight rings, screen magnification lenses, and window selection controls.

Key Technical Features & Capabilities
ScreenCaptureKit Hardware Efficiency: Captures full 60fps retina displays, specific app windows, or wired iPhone/iPad screens with minimal CPU and thermal load.
Driver-Free Internal Audio Capture: Captures clean application audio streams directly via macOS frameworks without installing fragile virtual sound drivers.
HEVC with Alpha & Presenter Overlay: Records transparent background video streams ready for Final Cut Pro / iMovie and overlays your live webcam feed seamlessly.
Mouse Highlights & Magnifier: Highlights mouse clicks with visual rings, magnifies regions during tutorials, and hides desktop icons automatically on record.

How to Use & Workflow
1
Select Capture Source: Choose Screen, Area, Window, Application, Audio Only, or connected Mobile Device from the compact control panel.
2
Tune Audio & Camera: Toggle Microphone, System Audio, or macOS Presenter Overlay webcam floating mode before starting capture.
3
Record with Real-Time Controls: Trigger recordings via global hotkeys and pause/resume seamlessly from the menu bar status icon.
4
Save High-Efficiency Video: Inspect completed MP4/MOV clips directly inside your configured output directory.
Troubleshooting & Common Issues
Issue: macOS prompts repeatedly or captures a blank desktop wallpaper.
*Cause*: macOS Screen Recording permission or System Audio Recording permission has not been enabled for QuickRecorder.
*Resolution*: Open System Settings › Privacy & Security › Screen & System Audio Recording, toggle QuickRecorder on, and restart the app.
Issue: Presenter Overlay mode is disabled in preferences.
*Cause*: Apple's hardware Presenter Overlay pipeline requires macOS 14 Sonoma or newer on Apple Silicon Macs.
*Resolution*: Enable the classic floating camera window option on macOS 12/13 systems.
