The app is signed ad-hoc (works on this Mac). For distribution: `make SIGN_ID="Developer ID Application: ..."` (notarization is still required).
## Installation
Build from source and install to `~/Applications`:
```
git clone <repository-url> second-display
cd second-display
make install
open ~/Applications/SecondDisplay.app
```
On first launch macOS asks for camera and microphone access — allow both. You can change this later in System Settings → Privacy & Security.
If you received a prebuilt copy that is not notarized, macOS blocks it. Allow it once in System Settings → Privacy & Security → "Open Anyway", or run `xattr -dr com.apple.quarantine SecondDisplay.app`.
## Usage
Menus at the top of the screen: **Video** (device, format), **Audio** (source or off), **Options** (prevent display sleep, start in full screen, always on top, mute ⇧⌘M, scaling), **Window** (tiling, full screen ⌃⌘F).
