Air-gapped Mac deployment protocol

Legal defense teams, defense contractors, healthcare researchers, and executive leadership frequently operate within strictly air-gapped environments where network interfaces are physically disabled. This guide outlines the protocol for deploying Oyma into air-gapped Mac facilities.

Pre-deployment preparation (Connected staging Mac)

1. Download the Oyma .dmg installer on your authorized staging computer.
2. Launch the application and download your required Whisper model weights:
   • For general meetings: Small (488 MB)
   • For maximum accuracy: Large v3 Turbo (1.6 GB)
3. Locate the downloaded model files in:

   ~/Library/Application Support/Oyma/models/

4. If using local LLM summaries, download the Ollama binary and run ollama pull llama3.2:3b.
5. Copy the application bundle, model weights, and Ollama files to an encrypted, approved transfer drive.

Air-gapped target Mac deployment

1. Connect the transfer drive to the air-gapped target Mac.
2. Copy Oyma.app into /Applications/.
3. Create the destination models directory and copy the model weights:

   mkdir -p ~/Library/Application Support/Oyma/models/
   cp -R /Volumes/TransferDrive/models/* ~/Library/Application Support/Oyma/models/

4. Launch Oyma.
5. Open Settings › Privacy and enable Local-Only Mode.
6. Select your local vault directory.

Verifying air-gapped integrity

Confirm zero network attempts in the Egress log. The ledger will display 0 requests sent across all session hours.
