Yet it’s the same Apple that wants us all to run Macs at full security and to eliminate third-party kernel extensions, but can’t find its way to building support for S.M.A.R.T. Users are therefore forced to make a choice: do they downgrade security and accept the risks of a third-party kernel extension so they can monitor storage connected via USB, or do they maintain full security and lose S.M.A.R.T.

Although this does apparently run on M1 series Macs as well as Intel models, macOS can’t run at Full Security on an M1 when it requires loading third-party kernel extensions. However, for any third-party utility to be able to monitor storage connected by USB, the SAT SMART kernel extension has to be installed. My favourite substitute remains DriveDx, but there are others, and the free command tools in smartmontools which enable you to roll your own with modest effort. status doesn’t even report when this was last checked, but several excellent third-party utilities give more detailed access. status.Īpple’s simplistic entry for S.M.A.R.T. This can be confirmed in Disk Utility, or in the Storage item in System Information, where the last entry for each supported physical drive gives its current S.M.A.R.T. FireWire support was rather better, and Thunderbolt should give S.M.A.R.T. attributes on storage connected using those ports. Clearly, to make any sense of these, an effective monitoring app needs a lot of additional manufacturer-specific information.Īlthough macOS has supported storage connected via USB-A ports since 1998 and USB-C since 2015, it has never supported access to S.M.A.R.T. Many are still aimed at hard disks, although S.M.A.R.T.

shows how allowing each storage manufacturer to define their own set of attributes and their values has led to many attributes and confusion over how to interpret them. are its lack of standardised indicators or attributes, and lack of support for reading them in macOS.Ī glance at the Wikipedia article on S.M.A.R.T. This is a bit like monitoring your body temperature when you think you might have an infection coming, in the expectation that a rise in temperature will precede the infection becoming more manifest, and will allow you to turn the alarm off and go back to sleep instead of going to work.
If you then monitor aspects of the device which deteriorate as a result of the same wear and tear, then as those variables start looking ominous, you’ll be able to anticipate more significant failure. The underlying theory is that the majority of disk/drive failures should occur as a result of wear and tear. But it’s far from standardised, and in many cases not even accessible. (most accurately including the stops/periods), it has been widely adopted across many types of storage device. First introduced in the ATA standard back in 1995 as Self-Monitoring, Analysis and Reporting Technology or S.M.A.R.T. It was another of those great ideas: build a monitoring system into the firmware of storage devices which could report signs of impending failure.
