First, I have confirmed that smartd outputs syslog, when something occurred.  On Macs, the log is /private/var/log/system.log.

Second, I have confirmed that NO syslog output from smartd, while the E-Mail regarding failed to read NVMe device SMART/Health information was sent.

The E-Mail would be sent when smartd was started via another program.  I mean that launchd, AppleScript, etc...

And the E-Mail NEVER sent when smartd was started via direct typing of command-line.  I mean that I use Terminal.app which is equivalent to command-prompt on Windows.

But the above is true only on macOS 13.x.  On prior macOS, like 11.x, 12.x, the mail would be sent. I have confirmed the above with 2 Macs and 3 version of macOS.


I'm now thinking that it might be a bug in macOS, how do you feel?
