While I'm not absolutely certain, looking at one of the OS headers
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/IOKit.framework/Versions/A/Headers/storage/ata/ATASMARTLib.h
I don't think macOS supports any immediate offline tests other than short and
long (in particular, not selective ranges), so I think smartmontools on macOS
is simply recognizing that - it runs on a lot of platforms, and not all of them
necessarily support every feature. macOS AFAIK doesn't support SMART at all on
USB or Firewire; and at least one other OS doesn't seem to fully support SMART
for ATA, for example.> On Jun 25, 2018, at 21:40, Ubence Quevedo <that...@gmail.com> wrote: > > Thanks for pointing this out. I’m disappointed this feature seems to be > disabled in macOS.
