Hey Product Hunt! I’m Kruszoneq, the maker of macUSB - Creating bootable ma OS X USB drives has never been easier!
I built it because after Apple’s move to Apple Silicon, preparing install media for older macOS / OS X versions became unexpectedly annoying (Terminal errors, expired cert headaches, random incompatibilities). macUSB turns that whole workflow into a simple, guided app.
What macUSB does:
• Creates bootable USB installers from .dmg / .iso / .cdr and raw .app installers
• Helps with legacy macOS / OS X use-cases on modern Macs
• Includes PowerPC USB boot instructions (Open Firmware steps) for vintage hardware
What’s new in the latest release:
It now supports making USB installers even for Mac OS X 10.4 Tiger (PowerPC) and adds clearer boot guidance for PPC Macs.
