A considered first launch.

Check your Mac.

Intel, Windows and iOS packages are not provided. Clean installation on another Mac remains an acceptance task.

Use your approved delivery.

1. Request beta access.

   Describe your intended evaluation at the beta request page. Requests are reviewed manually.

2. Receive an approved, time-limited link.

   Use only the delivery provided for your request. A request is not approval; the former public installer URL is closed.

3. Verify the file.

   Check the exact version, architecture, byte length and SHA-256 below. If the link has expired, request a new one; do not share private delivery URLs.

A checksum detects changed bytes. It does not establish Apple approval or independent malware certification.

Understand the trust status.

If you cannot install safely, use the browser facility. Do not interpret a blocked launch as a reason to bypass security.

Install the application.

1. Open the verified DMG.

   Read its installation, licence, privacy and third-party notices.

2. Copy the application to Applications.

   Drag GFIS Synthesis Preview.app to Applications. A complete copy is required—not an alias to the disk image or the developer's SSD.

3. Eject the installer.

   Launch from Applications. If macOS blocks the launch, stop and use the browser alternative.

4. Keep the correct app in the Dock.

   The Preview has its own name and profile. It does not replace the full owner workbench.

Make a first experiment.

1. Open Facility operations.

   Start the guided demonstration or inspect manually.

2. Advance a controlled scenario.

   Inspect one input change and observe the model response. Keep synthetic and measured evidence distinct.

3. Save, export and replay.

   Save an experiment, export JSON and check the replay. Review the memory guide before sharing files.

No online account is required for local use after installation. Full cloud-workspace and research permissions remain separate.
