mac signing (debug builds)

This app is usually built from scripts/package-mac-app.sh, which now:
  • sets a stable debug bundle identifier: com.clawdbot.mac.debug
  • writes the Info.plist with that bundle id (override via BUNDLE_ID=...)
  • calls scripts/codesign-mac-app.sh to sign the main binary, bundled CLI, and app bundle so macOS treats each rebuild as the same signed bundle and keeps TCC permissions (notifications, accessibility, screen recording, mic, speech). For stable permissions, use a real signing identity; ad-hoc is opt-in and fragile (see docs/mac/permissions.md).
  • uses CODESIGN_TIMESTAMP=auto by default; it enables trusted timestamps for Developer ID signatures. Set CODESIGN_TIMESTAMP=off to skip timestamping (offline debug builds).
  • inject build metadata into Info.plist: ClawdbotBuildTimestamp (UTC) and ClawdbotGitCommit (short hash) so the About pane can show build, git, and debug/release channel.
  • Packaging requires Bun: The embedded gateway relay is compiled using bun. Ensure it is installed (curl -fsSL https://bun.sh/install | bash).
  • reads SIGN_IDENTITY from the environment. Add export SIGN_IDENTITY="Apple Development: Your Name (TEAMID)" (or your Developer ID Application cert) to your shell rc to always sign with your cert. Ad-hoc signing requires explicit opt-in via ALLOW_ADHOC_SIGNING=1 or SIGN_IDENTITY="-" (not recommended for permission testing).

​
Usage

# from repo root
scripts/package-mac-app.sh               # auto-selects identity; errors if none found
SIGN_IDENTITY="Developer ID Application: Your Name" scripts/package-mac-app.sh   # real cert
ALLOW_ADHOC_SIGNING=1 scripts/package-mac-app.sh    # ad-hoc (permissions will not stick)
SIGN_IDENTITY="-" scripts/package-mac-app.sh        # explicit ad-hoc (same caveat)

​
Ad-hoc Signing Note

When signing with SIGN_IDENTITY="-" (ad-hoc), the script automatically disables the Hardened Runtime (--options runtime). This is necessary to prevent crashes when the app attempts to load embedded frameworks (like Sparkle) that do not share the same Team ID. Ad-hoc signatures also break TCC permission persistence; see docs/mac/permissions.md for recovery steps.

​
Build metadata for About

package-mac-app.sh stamps the bundle with:
  • ClawdbotBuildTimestamp: ISO8601 UTC at package time
  • ClawdbotGitCommit: short git hash (or unknown if unavailable)
The About tab reads these keys to show version, build date, git commit, and whether it’s a debug build (via #if DEBUG). Run the packager to refresh these values after code changes.

​
Why

TCC permissions are tied to the bundle identifier and code signature. Unsigned debug builds with changing UUIDs were causing macOS to forget grants after each rebuild. Signing the binaries (ad‑hoc by default) and keeping a fixed bundle id/path (dist/Clawdbot.app) preserves the grants between builds, matching the VibeTunnel approach.
