During December 2025, Bart Lagerweij enhanced the Homebrew/homebrew-cask repository by implementing Apple Silicon (ARM64) compatibility for the AWS VPN Client installation script. He focused on adapting the deployment process to support modern Mac hardware, addressing cross-architecture challenges and reducing installation friction for ARM64 users. Bart utilized Ruby and DevOps practices to integrate ARM64-aware scripting within the Homebrew Cask framework, ensuring seamless onboarding for users with newer macOS devices. While no critical bugs were addressed during this period, his work contributed to ongoing maintenance and improved the reliability of the AWS VPN Client installation flow for diverse Mac environments.
