1 suggestionThe vendor's official website (serialtool.com, dated March 2026) states that SerialTool runs on "macOS (Intel and Apple Silicon)", indicating a native Apple Silicon build is already available. If you are still running the older Intel-only version, download the latest installer from serialtool.com — the vendor's download page will serve the correct architecture for your Mac automatically. After installation, your existing settings, logs, and scripts will carry over without any manual migration needed. Updating will give you noticeably better performance and battery efficiency on M-series Macs, and ensures continued compatibility once Apple removes Rosetta 2 in macOS 28 (September 2028).
