SuperDuper! 4.0.7 Mac download

When a drive fails at 4 p.m. on a Friday, the Macs in a dental clinic can't wait for a cloud restore. SuperDuper! handles that job, making bootable copies of a startup disk, volume, or image file that you can boot from directly.

• Full-disk cloning for instant disaster recovery.
• Scheduled backups of important data run unattended.
• Script support lets you chain backup tasks with other maintenance.
• Works on both Apple Silicon and 64-bit Intel Macs.
• Runs on macOS 10.13 through the latest releases.
• Restores backups to the same or different hardware.

Weekly Full-System Clone in Three Clicks

For a weekly full-system clone, I start by connecting the external drive. Open SuperDuper!, select the source (the internal startup disk) and the destination (the external volume). The interface lists both clearly, no guessing. Choose "Clone" from the action menu. That tells the app to make a bit-for-bit copy.

The first pass takes a while — a couple hundred gigs of clinic records and imaging software. I let it run before lunch. The progress bar moves steadily, and a log window shows each block copied. No errors. When it finishes, I label the external drive with the date and store it in the office safe.

Mid-week, I use the scheduler. Set SuperDuper! to run a differential backup every Wednesday at 2 a.m. The automation handles the rest: attaches the backup drive, copies only changed files, ejects the drive after finishing. I check the log Thursday morning. Clean.

For a system migration — new Mac in the back office — I clone the old drive to an image file on a NAS. Then connect the new Mac to the network, boot from a SuperDuper! recovery media, and restore the image. Boots first try. No reinstall, no license hunting.

Any External Drive macOS Sees Works

Will it work with my external drive? SuperDuper! supports any drive macOS sees. USB, Thunderbolt, SATA enclosures. Format it as HFS+ or APFS, and the app lists it as a destination. No proprietary format needed.

Can I use it alongside Time Machine? Yes. Time Machine handles file-level hourly backups. SuperDuper! handles the whole-drive clone. They don't conflict. I keep both running: one for version history, one for instant bootable recovery.

Is it safe to clone a running system? SuperDuper! locks the source volume during the clone. It captures a consistent snapshot. I have done this dozens of times with live workstations. No corrupted clones.

Does it support encryption? It works with macOS-encrypted volumes. The app reads them during backup, writes the clone as a standard unencrypted volume by default. If you need the clone encrypted, you encrypt the destination volume through Disk Utility before the backup.

Missing Destination Drive Fix

Destination drive not showing up. The drive must be mounted and formatted before launching SuperDuper!. If it does not appear, quit the app, open Disk Utility, check the drive state, then relaunch. Unformatted drives do not appear in the source/destination list.

Clone fails partway through with a read error. This happens when the source disk has bad sectors. Run Disk Utility's Repair Disk on the source first. Then retry the clone. If the hardware is failing, replace the drive, do a manual file copy of critical data, and restore from there.

Bootable clone does not boot on the new Mac. SuperDuper! copies the boot volume exactly, but different hardware may need different firmware. Before cloning, check the new Mac's boot mode (UEFI vs. legacy) and disk partition scheme (GPT vs. MBR). Match the clone to the destination hardware. For T2- or T4-chip Macs, you may need to re-enroll the drive in the boot security system after the clone.

Scheduled backups do not run. The Mac must be awake during the scheduled window. If it sleeps, the backup skips. Use macOS Energy Saver settings to keep the machine on during the backup window. Also check that the backup drive is connected and writable before the schedule triggers.

After cloning, the original and clone have the same UUID. macOS sees duplicate drives. After the first boot from the clone, open Disk Utility, select the clone volume, and run Repair Volume. That reassigns a unique UUID. The clone then works without confusion.

SuperDuper! fits next to your existing tools: it covers the one gap Time Machine leaves, a bootable clone that actually saves the day.
