Backup app or comeback queen?

Mac backup favorite gets a glow-up and the comments are losing it
TLDR: SuperDuper!, a long-running Mac backup app, just got its first major full rewrite in ages, adding a simpler design and a safer preview feature. Commenters split between loyal fans celebrating a legend, confused readers asking what it even does, and skeptics comparing it to faster-moving rivals.
A beloved old Mac backup app just pulled off the software equivalent of a reality-show comeback. SuperDuper!, a tool people use to make full safety copies of their Macs, has been rebuilt from the ground up after years of quiet survival mode. The developer says this redesign has basically been sitting in a notebook since 2007, waiting for the day it could finally happen. Now it’s here with a cleaner look, simpler setup, and a new Preview mode that lets people see what would happen before anything changes. That last part had commenters practically clapping in the aisle.
But the real action was in the crowd reaction. One commenter immediately played the role of the chaotic friend yelling, “Can someone please say what this app even is?” That kicked off the classic tech-thread mini-drama: diehard fans talking like everyone already knows the lore, while confused readers begged for plain English. Others were deeply sentimental, praising the app’s famous “what’s going to happen?” explainer like it’s a lost art modern software forgot. One longtime user said they bought it well over a decade ago and it’s just kept working, which in app years is basically a golden wedding anniversary.
Not everyone was ready to throw confetti. A rival app, Carbon Copy Cloner, got name-dropped as the one that had been moving faster while SuperDuper! lagged behind. And one blunt “Yikes” commenter hinted the website changes looked rough enough to raise eyebrows. So yes: part victory lap, part old-school redemption arc, part comments-section custody battle over who really kept Mac backups alive.
