Install desktop

There is one Opensteer.app (com.opensteer.opensteer) and one Personal store. Stable and Beta are update channels selected in app Settings; fresh installs default to Stable. Both use accounts.opensteer.com for Account sign-in. Stable promotion copies the verified insider ZIP byte for byte, without another build.

Read signing constraints. Use the root Node/pnpm versions, Go, Xcode tools and the Android/JDK prerequisites in apps/agent-phone/README.md. Never read or operate on key material; the operator supplies a prepared signing configuration outside the checkout.

For an authorized local installation, close other Opensteer copies and use a clean checkout and explicit full source SHA:

pnpm desktop:install-local --source-sha FULL_40_CHARACTER_COMMIT_SHA --config /absolute/install-mac-local.json
