The latest macOS Sequoia 15.2 update prevents certain third-party apps from making bootable backups.
SuperDuper! developer Dave Nanian revealed the Replicator feature, which Apple controls and SuperDuper relies on, no longer functions in the final stages of making a backup with his app.
Apple has traditionally made it harder to make bootable backups citing security concerns and has lately pushed its inhouse Time Machine feature at the expense of third-party options.
This update may be seen as a deliberate attempt to phase out third-party apps for creating bootable backups in macOS.
If users want to create a backup of their Macs, Time Machine is Apple’s built-in backup feature that backs up files and restores a Mac to a previous state.
Backing up data is crucial, and users who rely on bootable external hard drives may need to reevaluate their backup strategy.
Apple may fix Replicator-related issues in the future or continue exercising control over third-party backup tools.
Possible loss of files is also a big concern, and it's suggested that Time Machine is not reliable enough to be the go-to backup option.
Apple may need to make Time Machine more reliable or provide options that allow third-party apps to make bootable drives.
Apple may stick to security concerns, likely leaving users with fewer options to recover their Macs quickly.
