macUSB

The tool guides users through creating bootable macOS and macOS X USB installers on both Apple Silicon and Intel Macs. It accepts an installer file, validates the target drive, formats the media automatically, and copies the necessary files, presenting the process in three clear stages: analysis, confirmation, and monitoring.

It supports modern macOS releases as well as legacy systems down to Mac OS X Tiger and Leopard, including Intel and PowerPC machines that require Open Firmware steps. The application checks USB media, provides live progress indicators, and offers post‑creation guidance for booting on older hardware.

Designed for macOS 14.6 or newer, the software replaces manual, error‑prone preparation with a guided workflow that handles disk formatting, file transfer, and cleanup, while delivering a summary of requirements and next‑step instructions for the target machine.
