About SuperDuper! 4.0.5 for Mac
SuperDuper! is a long-running Mac backup and disk cloning application developed by Shirt Pocket, an independent Mac software studio founded by David Nanian. Trusted by Mac users for over two decades — through the PowerPC, Intel, and Apple Silicon eras — SuperDuper! creates faithful, bootable copies of a Mac's startup drive, so a failed disk or a botched OS update becomes an inconvenience rather than a disaster. Version 4 represents a ground-up rebuild of the app on modern Apple technologies, introducing a significantly faster copy engine, a redesigned plain-English interface, and expanded flexibility over previous generations. What sets SuperDuper! apart from simpler file-copy utilities is its handling of complex system-level files, metadata, and permissions, combined with its signature Smart Update capability, which — in version 4 — has been "Turbocharged" so that subsequent backups can complete in under a minute. SuperDuper! 4.0.5, released August 26, 2026, is a quick fix release focused on correcting scheduled-execution issues, following closely on 4.0.4's reintroduction of disk image backup support. The app requires macOS 14 Sonoma or later and runs natively on both Apple Silicon and Intel Macs, making it a current, actively maintained option for anyone who wants a reliable, direct clone of their Mac in addition to (not instead of) Time Machine or a cloud backup service.
