Worked on the zed-industries/zed repository to enhance the developer onboarding experience for macOS 26 contributors. Focused on improving installation documentation by adding a robust fallback for the Metal toolchain setup, specifically addressing scenarios where Xcode had not yet been initialized. This involved updating Markdown-based documentation to include the xcodebuild -runFirstLaunch command, ensuring a smoother setup process and reducing common installation failures. Leveraged skills in documentation and macOS development to streamline the onboarding flow, resulting in faster contributor ramp-up and fewer support requests related to toolchain initialization. The work emphasized reliability and clarity in the installation process for new users.
