Why isn’t Drive Scope finding the SSD inside my Mac?

Some of the Macs Apple has released (2015-2017 MacBook, 2016-2017 MacBook Pro and the 2017 iMac), now use a new internal connection called NVMe (or PCI-Express) for their internal SSDs. While this is a much faster internal data connection, Apple has not yet (at the time of publication) provided a way to access the SMART data of the drives using this new connection type. Viewing the SMART status for your SSD in Apple’s Disk Utility (/Applications/Utilities) you will notice that ’S.M.A.R.T. status’ reports ‘Not Supported’.

We hope that SMART data for these drives will become available in the future, and that a future update to Drive Scope will include the ability to display SMART data for NVMe connected drives.
