Other issues[]
Former Apple employee Mike Bombich found that macOS 10.15.5 will incorrectly report success in creating a bootable backup of an APFS volume to third party backup applications when actually failing.[1] This issue was first identified during beta testing and was not addressed in the public release. Apple has not yet confirmed whether this is a bug or an intentional change as Apple had previously suggested at WWDC 2019 that developers should use Apple's own Apple Software Restore (ASR) utility.[2]
