5 Things macOS Borrowed From the Linux and Unix World
โš ๏ธ Important context first: macOS is built on Darwin BSD โ€” not Linux. They share Unix ancestry but are completely independent systems. This is about ideas and culture, not code.
๐Ÿ–ฅ Feature 01 โ€” The Terminal Is Real Unix
Every grep, awk, ssh, curl, and find command works natively on macOS. Mac developers work in a real POSIX Unix shell daily.
โšก๏ธ Feature 02 โ€” Zsh Was a Linux Default First

Created in 2009 because macOS had no package manager. Linux had APT since 1998. Homebrew now also runs natively on Linux.
๐Ÿ’พ Feature 04 โ€” ARM Was a Linux Story First
Android, Raspberry Pi (2012), AWS Graviton (2018). Linux ran ARM long before Apple M1 launched in November 2020.
