The developer of SuperDuper! says what they think is a bug in macOS Sequoia 15.2 has inadvertently broken how the app can create bootable backups — however, it may not be accidental at all.

It’s some years since Apple took steps to at least make it harder for people to start up their Macs using external drives. That was a privacy issue, a security issue, and a bit of a pain for anyone who remembers Mac drives failing.
Now according to developer Dave Nanian, Apple has gone further, maybe unintentionally. Nanian is the developer of backup app SuperDuper! and says that since macOS Sequoia 15.2 has changed a feature called the Replicator, his app has been unable to create a bootable backup.
