Select one of the Volumes present in the APFS container, by number or name
This submenu lists all the identified Volume names in the filesystem, so you can select one for further use. An APFS filesystem can have more than one volume, that all share the same pool of available freespace in the whole partition. Selecting a Volume will make that the ACTIVE volume, for which you can display the volume relevant information, and browse its contens On opening an APFS partition the FIRST volume (0) will be ACTIVE - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Press <F1> again for more help; Some options may require switching to 'Expert mode'
Refresh by finding the latest checkpoint and superblock (highest Xid value)
This refreshes the FS-view to the most recent CHECKPOINT This will re-read the master-superblock, then iterate over all the checkpoints present (usually hundreds) and select the Checkpoint-Map and associated superblock with the highest transaction-ID (Xid value) A checkpoint is a set of filesystem structures, representing a consistent view on the filesystem at one specific point in time. When the filesystem is still MOUNTED by the operating system, there may have been new transactions (changes) that are NOT reflected in the latest checkpoint yet. In that case the container is UNSTABLE and not all operations may work reliably. Refreshing just before performing an operation may help in that case When the filesystem is UNMOUNTED, and STABLE, there is no need to refresh, since there will be no new checkpoints created ... - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Press <F1> again for more help; Some options may require switching to 'Expert mode'

Unselect filesystem, reselect the same/first disk; enables Mode=FDISK menu
This will UNSELECT the current object/filesystem, and reselect a whole physical disk, either the same disk as the partition was on, or the first disk present in other cases. This is a quick way to change to 'Mode=FDISK' and work on disk-level issues - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Press <F1> again for more help; Some options may require switching to 'Expert mode'
