Looks to me like the code purposely and intentionally disallows that on a Mac. No idea why - maybe the OS won't do it or doesn't like it.
In os_darwin.cpp:
483 case ATA_SMART_IMMEDIATE_OFFLINE:
484 select = in.in_regs.lba_low;
485 if (select != SHORT_SELF_TEST && select != EXTEND_SELF_TEST)
486 {
487 errno = EINVAL;
488 return set_err(ENOSYS, "Unsupported SMART self-test mode");
489 }
490 err = smartIf->SMARTExecuteOffLineImmediate (ifp,
491 select == EXTEND_SELF_TEST);
492 break;
In other words, on a Mac, I think only -t long and -t short would work, not any
other -t options.
