Build 6080 fixes an issue in which CCC was not prompting to establish a bootable backup on Intel Macs running Big Sur (i.e. when the destination is freshly erased).

The user's preferred calendar (e.g. Gregorian, Thai, etc.) is now used when determining snapshot labels.

Addressed a small UI issue in which the task name and description would be truncated when restoring a custom sidebar width on launch.

Fixed an issue in which CCC would errantly indicate that your Mac is booted from an older OS than what is on the source, when the source is the current startup disk with a staged installation of the next available macOS update.

Addressed an issue in which the user would be prompted to erase the destination (again) despite having an installation of Big Sur. This was occurring when the destination volume was not currently mounted, and typically only after updating the system on the source volume.

Fixed an issue with selecting the Data volume of the startup disk on a remote Mac in the remote host browser. We also weed out read-only volumes, and some of the APFS helper volumes, because they're never valid sources or destinations in this context.

Fixed a logic issue in which the system file exclusion would be imposed upon a task that's backing up a folder to a volume in the startup disk's APFS container.

Fixed a regression that would lead to the System volume's contents to be loaded in the Task Filter window rather than the Data volume, making it impossible to exclude content from the task that is exclusive to the root of the Data volume (e.g. "cores" and "boot").

On macOS Big Sur, CCC now automatically proceeds with a data-only backup when a SoftRAID device is selected as the destination to a task that backs up the startup disk. macOS (Catalina and later) can't boot from a SoftRAID device, so there's no point in attempting to back up the system to those devices.

CCC now issues an error when dropping OneDrive placeholder files, along with directing the user to a Kbase article explaining why these files cannot be copied, and the implications this has on future restore activity.

Fixed an issue in which the Continue Anyway and Cancel buttons in the Cloning Coach could be errantly hidden when the window is attached as a sheet.
