Adom Hydrogen (macOS) — operate

The native macOS build of Adom Hydrogen. Apple Silicon (arm64) only, macOS 13+. First launch runs the whole setup automatically — no Homebrew, no Docker, no manual prerequisites. The app provisions its own Lima VM runtime, downloads the workspace image (cached after), and installs the current skills + editor tooling fresh from the wiki on every setup.

Install

Download the DMG from the Releases tab and drag Adom Hydrogen to Applications — releases are notarized and stapled, so Gatekeeper opens them without warnings. Or:

adom-wiki pkg install adom/hydrogen-macos

First launch (hands-free setup)

Launching the app runs the setup cascade, streaming each step live. The only prompts are a one-time Rosetta install and the Adom + Claude sign-in (saved Claude credentials restore automatically):

Installs Rosetta if missing (one click) — runs the x86-64 Adom tools in the workspace.
Provisions the Lima utility VM hd-builder (Apple Virtualization.framework), sized to the machine (¼ RAM / 5% disk defaults; adjustable in Settings).
Downloads the golden image, imports + boots the Adom-Workspace machine.
Installs the Hydrogen skills, editor extensions, and settings from the wiki.
Starts the editor (code-server), signs in to Adom + Claude, and opens the first AI conversation.

Troubleshooting

"Rosetta is required" gate, or the workspace download hangs forever — you're almost certainly running inside a nested VM (e.g. VirtualBuddy). Apple Silicon doesn't support nested virtualization, so the workspace VM can't boot. Run on a real Mac (a separate user account is a fine clean test environment).
Workspace won't start — check the VM: limactl list should show hd-builder running. Inspect the machine: limactl shell hd-builder -- sudo machinectl list (expect Adom-Workspace).
Workspace stopped after quitting the app — that's the default (On Close → "Stop workspace"). Change it in Settings to keep the VM running in the background.
Reset the VM (re-provision from scratch): limactl delete hd-builder, then relaunch the app. Or use the app's own reset panel (Setup → Reset) for a guided virgin reset.

Uninstall

Double-click Uninstall Adom Hydrogen on the DMG (guided tiers: app / workspace VM / Adom Bridge companion), or:

adom-wiki pkg uninstall adom/hydrogen-macos

# Adom Hydrogen (macOS) — operate

The native macOS build of Adom Hydrogen. Apple Silicon (arm64) only, macOS 13+.
First launch runs the whole setup automatically — no Homebrew, no Docker, no manual
prerequisites. The app provisions its own Lima VM runtime, downloads the workspace
image (cached after), and installs the current skills + editor tooling fresh from the
wiki on every setup.

## Install

Download the DMG from the Releases tab and drag **Adom Hydrogen** to
**Applications** — releases are notarized and stapled, so Gatekeeper opens them
without warnings. Or:

```bash
adom-wiki pkg install adom/hydrogen-macos
```

## First launch (hands-free setup)

Launching the app runs the setup cascade, streaming each step live. The only prompts
are a one-time Rosetta install and the Adom + Claude sign-in (saved Claude
credentials restore automatically):

1. Installs **Rosetta** if missing (one click) — runs the x86-64 Adom tools in the workspace.
2. Provisions the Lima utility VM `hd-builder` (Apple Virtualization.framework),
   sized to the machine (¼ RAM / 5% disk defaults; adjustable in Settings).
3. Downloads the golden image, imports + boots the `Adom-Workspace` machine.
4. Installs the Hydrogen skills, editor extensions, and settings from the wiki.
5. Starts the editor (code-server), signs in to Adom + Claude, and opens the first
   AI conversation.

## Troubleshooting

- **"Rosetta is required" gate, or the workspace download hangs forever** — you're
  almost certainly running inside a **nested VM** (e.g. VirtualBuddy). Apple Silicon
  doesn't support nested virtualization, so the workspace VM can't boot. Run on a real
  Mac (a separate user account is a fine clean test environment).
- **Workspace won't start** — check the VM: `limactl list` should show `hd-builder`
  running. Inspect the machine: `limactl shell hd-builder -- sudo machinectl list`
  (expect `Adom-Workspace`).
- **Workspace stopped after quitting the app** — that's the default (On Close →
  "Stop workspace"). Change it in Settings to keep the VM running in the background.
- **Reset the VM** (re-provision from scratch): `limactl delete hd-builder`, then
  relaunch the app. Or use the app's own reset panel (Setup → Reset) for a guided
  virgin reset.

## Uninstall

Double-click **Uninstall Adom Hydrogen** on the DMG (guided tiers: app / workspace
VM / Adom Bridge companion), or:

```bash
adom-wiki pkg uninstall adom/hydrogen-macos
