SuperDuper!

To create a bootable backup, open SuperDuper! and select your Mac's internal drive as the source and an external hard drive as the destination. Choose the "Backup - all files" script from the drop-down menu, then click "Copy Now." Once the cloning process finishes, your external drive will be an exact, bootable replica of your macOS system.

Yes, SuperDuper! is actively maintained by Shirt Pocket software and supports modern macOS versions, including macOS Sonoma. However, because Apple's newer Macs use Apple Silicon chips, you may need to adjust your Security & Privacy settings to allow the software to function properly. Always check the developer's website for the latest compatibility notes before updating your OS.

The base version of SuperDuper! is completely free to download and use for creating full, manual bootable clones of your Mac. However, to unlock the "Smart Update" feature, which only copies new and changed files to save time, you must purchase the full version. The paid version also includes advanced scheduling options to automate your backups.

SuperDuper! cannot directly clone your system to a network-attached storage (NAS) device over a standard network connection. The destination drive must be locally mounted, such as a USB, Thunderbolt, or FireWire drive. However, you can back up to a sparse bundle disk image stored on a network drive, though it will not be directly bootable.
