Contributed to the Homebrew/homebrew-cask repository by enhancing the deployment and security of the Deadbolt macOS application. Addressed a Gatekeeper compliance issue by implementing a Ruby-based signing fix, which restored Deadbolt’s operability on macOS by ensuring it passed security checks. Updated the cask release packaging to support Deadbolt version 2.1.1, including adjustments to version metadata and SHA256 checksums for improved release integrity. Focused on cask management and package management workflows, these changes strengthened macOS security compliance and streamlined the deployment process, resulting in more reliable application releases and a smoother experience for end users and maintainers alike.
