The 49-Day Trap: Critical TCP Networking Bug in macOS

A critical bug in macOS causes TCP networking to fail completely after 49.7 days of system uptime, posing a serious threat to servers and always-on systems that depend on uninterrupted connectivity. This timing-based flaw, likely stemming from an integer overflow or timer wraparound, silently cripples network functionality and could trigger widespread outages in production environments. The discovery underscores how subtle timing bugs in core system components can have devastating real-world consequences for infrastructure reliability.
