macOS Remote Desktop Client
===========================
Prerequisites:
1. Xcode Command Line Tools: xcode-select --install
2. CMake: brew install cmake
Build:
chmod +x build.sh
./build.sh
Or manually:
mkdir build && cd build
cmake ..
make
Run:
./build/bin/ghost
Configuration:
Server address is configured in main.mm (g_SETTINGS variable).
Modify before building if needed.
Permissions Required:
1. Screen Recording - System Settings > Privacy & Security > Screen Recording
2. Accessibility - System Settings > Privacy & Security > Accessibility
Features:
[x] Screen capture (CGDisplayCreateImage)
[x] H264 video encoding (VideoToolbox)
[x] Mouse control (move, click, drag, scroll)
[x] Keyboard control (full VK code mapping)
[x] Retina display support (coordinate scaling)
[x] Network connection (IOCPClient)
[x] LOGIN_INFOR (system info reporting)
[x] Heartbeat with RTT estimation
[x] Active window tracking
[x] Quality level adjustment (FPS/algorithm)
Files:
CMakeLists.txt - Build configuration
Permissions.h/mm - macOS permission handling
ScreenHandler.h/mm - Screen capture and H264 encoding
InputHandler.h/mm - Mouse/keyboard simulation
H264Encoder.h/mm - VideoToolbox H264 encoder
SystemManager.h/mm - Process management
main.mm - Entry point, LOGIN_INFOR, heartbeat
Quality Levels:
Level 0: 5 FPS, Grayscale (emergency low bandwidth)
Level 1: 10 FPS, RGB565
Level 2: 15 FPS, H264 (default, office work)
Level 3: 20 FPS, H264
Level 4: 25 FPS, H264
Level 5: 30 FPS, H264 (smooth)
Notes:
- First frame is always raw bitmap (TOKEN_FIRSTSCREEN)
- Subsequent frames use H264 encoding (TOKEN_NEXTSCREEN)
- Coordinates are scaled for Retina displays automatically
- Windows VK codes are mapped to macOS key codes
