Disk Utility’s First Aid in Catalina

Howard Oakley:

The description of Disk Utility’s First Aid command therefore appears incorrect. How this currently works is that performing First Aid depends on the item which is selected. If that’s a disk, then First Aid checks and repairs at that level, including the disk’s partition map and EFI partition, not its volumes. To perform full checks on an APFS volume, you should select that volume (not its disk or container) before clicking on the First Aid tool. To check and repair all volumes in a container, you must first eject each of its volumes, then select the container and click on the First Aid tool. Or run First Aid on them individually.

This all makes sense, apart from Disk Utility’s apparent inability to unmount volumes in order to check a container, but isn’t what the user is told in the app’s Help book.

Too bad you can’t tell it to check everything all at once, or do multiple operations in separate windows, as was possible in macOS 10.10 and earlier.
