SuperDuper! v3.3.1: Heroic System Recovery for Mere Mortals. Catalina compatible, and smarter than ever.
Back-to-back 2005 and 2006 Eddy Award Winning...and compatible with the Mac you're using.
I used the free version of Superduper to create a clone image on an external firewire drive but it doesn't seem to work. The cloning process goes through to completion ok, apparently, but I can't get the computer to boot up from the external drive. I tried holding down the option key before I. All of them have free or trial versions, so you can check out which one works best for you. We’ll further show how to clone a Mac hard drive using a SuperDuper! It’s been around for a long time but it runs on a vast variety of macOS versions, including the most recent one, macOS Catalina.
Big Sur InfomationSuperDuper! v3.5, which is Big Sur compatible and produces bootable Intel and M1 backups, is now in Beta: see the Shirt Pocket blog for information.
We're happy to announce the immediate availability of SuperDuper! 3.3.1, the latest version of our popular disk copying utility for macOS.
Superduper Mac Free Trial
3.3.1 is fully compatible with Catalina, the latest release of macOS, and produces fully bootable HFS+ and APFS backups faster and easier than ever. It even supports creating and copying from snapshots! You can keep your backup on its own volume, or you can even store and Smart Update it alongside your Time Machine backups. We even let you copy your Time Machine backups to other disks, so you can back them up or upgrade to a larger disk without losing your history!
And we've improved our super-cool new Smart Delete feature, which helps to banish 'disk full' errors to the land of wind and ghosts, without any speed penalty; a Smart Wake feature to ensure your backups happen whether your Mac is awake or asleep; and the ability to turn off 'missing drive' errors during scheduling...plus a lot more.
But of course we didn't abandon our non-Mojave users. 3.3.1 is still compatible with Yosemite (10.10) and later, and as always we've made improvements for everyone. And, of course, 3.3.1 still includes all the other terrific features of SuperDuper!, including: the ability to easily schedule backups; many imaging options; more control over shutdown; AppleScript support; hundreds of UI improvements; Growl support; and an extensive, task-based User's Guide.
SuperDuper! also includes Smart Update, a great feature that updates a clone to exactly reflect any changes on the original in just minutes!
Once again, it's a free update for existing customers. Copies will auto-upgrade, but you can also download now!
SuperDuper is the wildly acclaimed program that makes recovery painless, because it makes creating a fully bootable backup painless. Its incredibly clear, friendly interface is understandable, easy to use, and SuperDuper's built-in scheduler makes it trivial to back up automatically. It's the perfect complement to Time Machine, allowing you to store a bootable backup alongside your Time Machine volume—and it runs beautifully on your Mac!
SuperDuper's interface confirms all your actions in simple, clear language to ensure that the end result is exactly what you intended.
