SuperDuper 4 is a ground-up rewrite of the 22-year-old Mac backup utility, originally designed in 2007 but only now realized. Key changes include replacing document-based workflows with Copy Jobs organized by source, a new Preview mode that runs a copy without making changes, and a Turbo feature that reduces Smart Update time from 40 minutes to roughly 1 minute for large volumes. The app now supports any macOS-compatible file system (including exFAT and NAS volumes), runs backups as a background helper process (even after logout), supports simultaneous multiple backups, replaces Copy Scripts with Copy Rules, and adds Apple Shortcuts integration. SuperDuper 4 requires macOS 14 Sonoma or later. It is the first paid upgrade in the product's history; existing customers who purchased after July 31, 2020 receive up to a 30% discount, and qualifying recent purchases get it free.

How much faster is SuperDuper 4 Smart Update compared to SuperDuper 3?
SuperDuper 4 Smart Update is roughly 2x faster without Turbo mode, and up to 40x faster with Turbo enabled. A real-world example: an 8-million-file, 2.5TB volume that previously took 40 minutes now takes about 20 minutes without Turbo, and approximately 1 minute with Turbo — a reduction far exceeding the advertised order-of-magnitude improvement.
