Developed ARM architecture support for the Hubstaff Cask in the XcodesOrg/homebrew-cask repository, enabling seamless installation and verification of Hubstaff on Apple Silicon Macs. The work involved updating Ruby-based cask management logic to handle architecture-specific download URLs and SHA256 checksums, ensuring that ARM-based systems receive the correct build. Tests were added to validate the ARM build path, reducing manual remediation and installation failures for Apple Silicon users. Documentation and code comments were updated to reflect the new multi-architecture support, aligning with the broader roadmap for cross-architecture parity. The work demonstrated proficiency in MacOS development and Ruby programming.
