## Why
|
|
|
|
The portable Meeting Assistant build runs on macOS, but starting a recording resolves `UnavailableMeetingAudioSource` and fails before any audio reaches transcription. macOS users need the same microphone-plus-computer-output capture contract without changing the established Windows NAudio implementation.
|
|
|
|
## What Changes
|
|
|
|
- Add native macOS microphone capture through AVFoundation.
|
|
- Add native macOS computer-output capture through ScreenCaptureKit.
|
|
- Stream both sources as 16-bit PCM into the existing alignment, echo-cancellation, gain, mixing, recording, and transcription pipeline.
|
|
- Select the macOS sources only when the portable build is running on macOS; retain the existing compile-time Windows registrations unchanged.
|
|
- Package a small Swift capture helper in macOS build and publish output.
|
|
- Produce a short mixed WAV from live microphone and system PCM emitted by the implemented native capture helper as operational evidence.
|
|
- Verify the public recording endpoints, managed macOS adapters, mixer, and stop behavior together with deterministic process-boundary audio.

### Modified Capabilities
|
|
|
|
- `meeting-recording`: Extend microphone and computer-output recording to macOS while preserving Windows behavior.
