During February 2026, Mmt enhanced the reliability of the macOS notarization process for the Concordium/concordium-node repository by developing an automated retry mechanism to address transient network failures. Leveraging bash scripting and devops practices, Mmt integrated resilient error handling into the CI pipeline, reducing manual intervention and minimizing build interruptions. This feature improved the success rate of macOS notarization, resulting in more stable and predictable release cycles. The work demonstrated a focused application of scripting and macOS development skills, delivering a targeted solution that strengthened the release engineering workflow and contributed to the overall robustness of Concordium’s deployment process.
