[NEWS] macOS Sequoia 15.2 Breaks SuperDuper Bootable Backups

    macOS Sequoia 15.2 Breaks SuperDuper Bootable Backups
    -----------------------------------------------------
    Apple's latest macOS Sequoia 15.2 update has introduced a
    critical bug that prevents the popular backup utility
    SuperDuper from creating bootable backups, according to
    the app's chief developer, Shirt Pocket's Dave Nanian.
    The issue stems from a "Resource Busy" error that occurs
    during the final stages of the backup process when
    attempting to copy system preboot or recovery files. While
    similar errors in the past could be resolved by keeping
    the system awake during backup, Ninian reports that this
    new bug appears to be more fundamental.
    The problem originates from Apple's earlier decision to
    restrict third-party apps from directly copying the
    operating system, instead requiring them to use Apple's
    own replication tools. With these tools now malfunctioning
    in macOS 15.2, SuperDuper and potentially other backup
    utilities are unable to create complete bootable backups.
    As a temporary workaround, SuperDuper users can still back
    up their applications, data, and settings using the app's
    "Backup - all files" option with "Smart Update" enabled.
    However, this method won't create a bootable backup that
    can be used for immediate system recovery.
    Shirt Pocket has filed a bug report with Apple and is
    awaiting a resolution, but Nanian is keen to emphasize that
    since the issue lies within Apple's system components,
    third-party developers cannot implement their own fixes.
    The timing of this bug is particularly concerning for users
    who rely on bootable backups as part of their data
    protection strategy, especially given the recent release of
    macOS 15.2 and the potential for other undiscovered issues.
