Code Review

This pull request adds a helpful troubleshooting section to the README.md for macOS users. My review includes a suggestion to improve the clarity and completeness of the new instructions. I've also pointed out that coverage.xml, a generated report file, has been included in the commit. Such files should typically be excluded from version control to keep the repository clean.
