## What it is
macUSB is a native macOS app (Swift/SwiftUI) for creating bootable USB media on Apple Silicon and Intel Macs. It supports macOS, Linux, and Windows ISO flashing, includes a built-in macOS installer downloader from Apple servers, and handles legacy macOS installer compatibility issues on Apple Silicon.

## Use cases
- create a bootable macOS installer USB on Apple Silicon
- flash a Linux ISO to a USB drive from my Mac
- make a bootable Windows 11 USB without a Microsoft account requirement
- download official macOS installers directly from Apple
- create bootable USB for old macOS versions like Catalina on a modern Mac
- split oversized Windows wim files to fit FAT32
- find a Rufus alternative for macOS

## When to choose
- you need a guided, all-in-one bootable USB creator on macOS
- you want to create legacy macOS installers on Apple Silicon where standard tools fail
- you want to download verified macOS installers without third-party mirrors
- you prefer a native Swift app over Electron-based tools

## When to avoid
- you need to create bootable USB media on Linux or Windows
- you need scripting or CLI automation rather than a GUI workflow
- you require APFS target drives to be auto-reformatted (manual Disk Utility step needed)
- you need wim splitting without installing wimlib separately
