Install on macOS

The native consumer product currently targets Apple Silicon Macs.

Requirements

• Apple Silicon Mac (arm64).
• macOS 26 for Apple's container runtime.
• Administrator approval once during verified runtime installation.

Install

1. Download the current DMG.
2. Open it and drag 1Helm to Applications.
3. Open 1Helm. Gatekeeper verifies the Developer ID signature and notarization ticket.
4. Complete Captain → Providers → Workspace. Approve Apple's signed runtime inline if requested.

Data and upgrades

Application state lives under ~/Library/Application Support/1Helm. Profile → Check for updates asks the Mac hosting 1Helm to download and verify the signed, notarized update. When the host reports it ready, Restart & install quiesces the local service and replaces the app. The browser is never given a DMG as the update action, and Application Support remains in place.

Removal

Use Settings → Admin → Prepare to remove 1Helm before trashing the app. This removes only verified 1Helm-owned channel machines while preserving Application Support for a future reinstall.
