Developed native ARM64 support for the JumpCloud Password Manager within the lizongying/homebrew-cask repository, focusing on package management and macOS development using Ruby. The work involved introducing an ARM64-specific download URL and explicit SHA256 checksums, ensuring secure and architecture-aware distribution of the application. By removing the Rosetta dependency, the update enabled direct native builds on Apple Silicon devices, resulting in faster and more reliable installations. This change improved release traceability and artifact integrity across the repository, reducing build friction and supporting broader user adoption. No bugs were reported during this period, reflecting a focused and robust implementation.
