Tar Files Created on macOS Display Errors When Extracting on Linux (2024) | Hacker News

A Hacker News thread discussed how tar archives created on macOS can carry Apple-specific filesystem metadata.

When those archives are extracted on Linux, the metadata may appear as odd files or extraction errors, such as .DS_Store or resource-fork artifacts.

Commenters debated whether this is a bug or expected behavior, but the bigger issue is portability across platforms.

The discussion underscored a common build and packaging pitfall: Mac-made archives may not be reproducible or clean on Unix-like systems.
