That's it. The command records the persistent codeburn CLI path, downloads the latest .app from the newest mac-v* GitHub Release with a matching checksum, verifies it, drops it into ~/Applications, clears Gatekeeper quarantine, and launches it. Re-running it upgrades in place with --force, or just launches the existing copy otherwise.

Build from source

For contributors running a local build instead of the packaged release:

npm install -g codeburn                       # CLI the app shells out to for data
git clone https://github.com/getagentseal/codeburn.git
cd codeburn/mac
swift build -c release
.build/release/CodeBurnMenubar                # launch

On macOS 14 (Sonoma) without Xcode 16

swift build above assumes the macOS 15 SDK, whose SwiftUI marks the View protocol @MainActor. The Sonoma SDK (shipped with Command Line Tools) lacks that annotation, so a plain build fails with ~80 main actor-isolated ... from a nonisolated context errors.

(The -10825 launch failure itself is fixed by Package.swift's .macOS(.v14) deployment target: ld64 drops the macOS-15-only libswift_errno.dylib dependency for any build with that target, regardless of which SDK built it, including the CI-distributed release. This local-build path exists only for the narrower case of building on a Sonoma machine with nothing but the Command Line Tools, where the SDK's un-annotated View protocol needs the @MainActor patch below.)

Use the helper, which builds against the local macOS 14 SDK with a standalone swift.org Swift 6.x toolchain and adds explicit @MainActor to the views in a scratch copy (repo sources stay clean), producing a minos = 14.0 bundle installed to ~/Applications:

mac/Scripts/build-local.sh         # then: codeburn menubar

Build & run (dev against a local CLI checkout)

cd mac
swift build
# Point the app at your dev CLI build instead of the globally installed `codeburn`:
npm --prefix .. run build
CODEBURN_ALLOW_DEV_BIN=1 CODEBURN_BIN="node $(pwd)/../dist/cli.js" swift run

The app registers itself as a menubar accessory (LSUIElement = true at runtime). No Dock icon.

Data source

On launch and every 60 seconds thereafter, the app spawns codeburn status --format menubar-json --no-optimize directly (argv, no shell) via CodeburnCLI.makeProcess and decodes the JSON into MenubarPayload. The manual refresh button in the footer invokes the same command without --no-optimize, which includes optimize findings but takes longer.

Release installs record a persistent absolute CLI path in ~/Library/Application Support/CodeBurn/codeburn-cli-path.v1, then fall back to Homebrew's common codeburn locations. For development only, set CODEBURN_ALLOW_DEV_BIN=1 with CODEBURN_BIN; the value is validated against a strict allowlist before use, so a malicious env var can't inject shell commands.

Status

Live data wired. Next iterations:

FSEvents watch for ~/.claude/projects/ changes (debounced refresh on real edits)
Persistent disk cache for optimize findings so the default refresh can include them without the 30-second penalty
Currency metadata in the JSON payload + Swift-side formatting
Sparkle auto-update
DMG packaging + Homebrew Cask tap
