Igneum Miner for Mac (packaging/mac)

A DMG a miner opens on an Apple silicon Mac: drag the app to Applications, open it, answer two questions, mine. Version 0.3.0 (4 October 2026) is the app: a branded window (no Terminal), the engine that runs the node and the miner, a menu-bar item, settings, an update check. 0.1.0 and 0.2.0 (3 and 4 October 2026) were the Terminal launchers; the 0.2.0 run script's command lines live on inside the engine (app/igneum-app/src/engine.rs).

Build

packaging/mac/build-dmg.sh

Output: packaging/mac/dist/Igneum-Miner-0.3.0.dmg (about 20 MB, lzfse). The script compiles the engine (app/igneum-app, cargo build --release, nice 19 and 4 jobs because the devnet mines on this Mac), the window (app/mac/IgneumMiner.swift, swiftc -target arm64-apple-macos11) and the Metal worker (proto-metal/main.swift, same target), takes igneumd and igneum-miner from vendor/igneum-node/target-integration/release (the devnet-v4 integration build; NODE=, MINER=, WORKER=, ENGINE= override), strips and ad-hoc signs the copies, checks each one runs, writes igneum-app.json (below) and lays the image out with dmgbuild (pip3 install dmgbuild; without it a plain hdiutil image). The icon is brand/icons/igneum.icns, the DMG art brand/icons/dmg-background.tiff (python3 brand/icons/make-icons.py). build/ and dist/ are ignored by git.

The bundle

Igneum Miner.app/Contents/MacOS/Igneum Miner        the window: WKWebView + NSStatusItem (app/mac/IgneumMiner.swift)
Igneum Miner.app/Contents/MacOS/igneum-app          the engine (app/igneum-app)
Igneum Miner.app/Contents/Resources/bin/igneumd, igneum-miner, igneum-bench
Igneum Miner.app/Contents/Resources/igneum-app.json  packaged configuration (packaged-config.sh writes it)
Igneum Miner.app/Contents/Resources/igneum.icns
Igneum Miner.app/Contents/Info.plist                 app/Info.plist (CFBundleVersion = build stamp, LSMinimumSystemVersion 11.0)

The window starts igneum-app --wrapper, reads URL ... and STATE {...} lines from its stdout, shows the URL in the web view and keeps the menu-bar title (hash rate, paused, syncing). Quit writes quit to the engine's stdin and waits for EXIT (up to 45 s): the miners stop first (8 s grace), then the node (30 s), then the last log upload. Closing the window hides it; the app lives on in the menu bar and the Dock. The engine serves the dashboard on 127.0.0.1:<random port>/t/<32-hex token>/; nothing without the token answers. Links off 127.0.0.1 open in the default browser.

igneum-app.json (never in the UI source): update_manifest = https://dl.igneum.network/dl/<token>/igneum-app-latest.json with the token read from ~/.config/igneum/dl-token at build time (missing file = update check off), the log intake URL and key (the key only authorises uploads, as the 0.2.0 launchers shipped it), the live page. The manifest the engine expects: {"version":"0.3.1","mac":{"url":"...dmg","notes":"..."},"windows":{"url":"...exe","notes":"..."}}; a newer version shows a banner with a Download button (opens the URL in the browser). Checked 20 s after start and every 6 h, and from Settings.

Gatekeeper: the app is unsigned (ad hoc). Right-click > Open the first time. The engine strips com.apple.quarantine from the bundle's Contents on start, so the binaries inside are not refused one by one; that needs a writable volume, hence "drag to Applications first".

What the engine does (app/igneum-app)

Pause stops the miners and keeps the node. Settings restart only the affected worker.
