@lobechat/electron-mac-notifications

Native N-API addon that posts macOS notifications through UNUserNotificationCenter, styling them as communication notifications (sender avatar as the primary icon, via INSendMessageIntent) when a sender is provided. Consumed by the desktop main process; falls back gracefully everywhere it can't run.

Build

pnpm --filter @lobechat/electron-mac-notifications build:native

No-op on non-darwin platforms. The desktop packaging pipeline runs this automatically in beforePack.

Runtime requirements (all empirically verified)

The avatar treatment only renders when the host app satisfies all of:

1. Signed with a real certificate and launched as a regular app. Adhoc-signed dev Electron gets UNErrorDomain Code=1 from the notification center, and this package then reports isSupported() but fails at show-time — callers fall back to Electron's Notification.
2. com.apple.developer.usernotifications.communication entitlement in the signature. Never add it without requirement 3: launchd refuses to spawn the app (POSIX 163).
3. An Apple provisioning profile authorizing the entitlement, embedded at Contents/embedded.provisionprofile. Wired through MAC_PROVISIONING_PROFILE + APPLE_TEAM_ID in electron-builder.mjs.
4. NSUserActivityTypes = [INSendMessageIntent] in Info.plist (set unconditionally via mac.extendInfo).

Without 2–3 the notification still shows as a plain banner — macOS silently drops the communication styling — so profile-less channels keep working.

Delegate ownership

The addon takes over the process-global UNUserNotificationCenter delegate. Notifications whose identifier lacks the lobehub- prefix are forwarded to whatever delegate was installed before (Electron's own Notification module), so the two paths can coexist during fallback.
