tom_doerr · x · 2026-09-03
macUSB is a free, open-source macOS app (2.7k stars on GitHub) that makes bootable USB media on both Apple Silicon and Intel Macs, using either its built-in macOS downloader or local installer files.
- Why it exists: creating installers for macOS Catalina and older on modern Macs — especially Apple Silicon — is notoriously tricky, as legacy workflows often clash with newer system requirements. macUSB wraps the process in a guided flow built on solutions the author verified through hands-on troubleshooting.
- Install: free via GitHub Releases or brew install --cask macusb, with all features available to everyone.
