Miles Wolbe<\/a> (Hacker News<\/a>):<\/p>\n

Plugging in an unformatted external drive produces the usual alert, “The disk you inserted was not readable by this computer. Initialize… | Ignore | Eject”, but clicking Initialize just opens Disk Utility without the disk appearing<\/p>

As shown above, clicking View > Show All Devices does not cause the raw disk to appear.<\/p><\/blockquote>\n

Disk Utility has been a disaster since it was rewritten for El Capitan<\/a>. It now has a single window, so you can only do one action at a time even though actions may take many hours. It’s missing key features related to Core Storage. Mounting\/unmounting and partitioning often fail. Strangely, I’ve not had any problems when using the underlying diskutil<\/tt> command directly.<\/p>\n

High Sierra did fix the bug from Sierra where Disk Utility would always show the tab bar, with a single giant tab, even though it did not let you create more tabs.<\/p>\n\n

Software quality at @apple in 2017 (in #DiskUtility):<\/p>\n

1. greyed-out text for disabled item is barely legible over dark-blue background selection colour; <\/p>\n

2. volume is unmounted but the “Rename” menu item is still enabled (and doesn’t do anything, of course).<\/p>\n<\/blockquote>\n\n

Update (2018-01-19): Lloyd Chambers<\/a>:<\/p>\n

Ultimately I failed to be be able to use Disk Utility at all to restore the system to a single volume. Total brick wall impossible.<\/p>\n<\/blockquote>\n\n
