 ### Fixes
 
+- macOS/Build: default release packaging to `BUNDLE_ID=ai.openclaw.mac` in `scripts/package-mac-dist.sh`, so Sparkle feed URL is retained and auto-update no longer fails with an empty appcast feed. (#19750) thanks @loganprit.
+
 - Signal/Outbound: preserve case for Base64 group IDs during outbound target normalization so cross-context routing and policy checks no longer break when group IDs include uppercase characters. (#5578) Thanks @heyhudson.
 - Providers/Copilot: add `claude-sonnet-4.6` and `claude-sonnet-4.5` to the default GitHub Copilot model catalog and add coverage for model-list/definition helpers. (#20270, fixes #20091) Thanks @Clawborn.
 - Dependencies/Agents: bump embedded Pi SDK packages (`@mariozechner/pi-agent-core`, `@mariozechner/pi-ai`, `@mariozechner/pi-coding-agent`, `@mariozechner/pi-tui`) to `0.54.0`. (#21578) Thanks @Takhoffman.
