balenaEtcher vs RufusMac

balenaEtcher flashes operating system images to SD cards and USB drives, and can create USB installation media from bootable ISOs. Its three-step interface requires no command line. After flashing, it confirms completion to help users check that a card can boot and is not corrupted. To reduce the risk of choosing the wrong target, it warns users and hides system drives by default. Flashing erases the entire target drive and replaces its data. Etcher runs on Linux, macOS, and Windows: listed support covers most Linux distributions on Intel 64-bit systems, Windows 10 and later on Intel 64-bit systems, and macOS 10.13 and later on Intel and Apple Silicon. It can directly flash Raspberry Pi devices that support USB device boot mode. Etcher is free and open source. It does not configure persistent storage for live USB drives, and Windows images may need special boot preparation that Etcher is not designed to perform.

RufusMac is a free, GPLv3 open-source macOS app for creating bootable USB installers for Windows, Linux, and other systems. It writes ISO, IMG, and DMG images and detects Windows or Linux automatically. Windows 11 options can bypass TPM 2.0, Secure Boot, RAM and CPU checks, and the online-account requirement. The app verifies an image before writing and the drive afterward with SHA-256 checksums. Its built-in catalog links to official downloads including Ubuntu, Fedora, Debian, Mint, Arch, Kali, Tails, and Windows. RufusMac lists only external physical removable disks, previews write commands, and requires explicit confirmation; writing erases the selected drive. The rmctl companion can list drives, preview command pipelines, browse the catalog, and verify checksums. It requires macOS 26 (Tahoe) or later on Apple silicon. The repository describes a functional v0.1 preview, has no releases available, and identifies the app as unsigned. Multiboot and Linux persistence remain experimental and need real-hardware validation.
