Drive Genius 5 & macOS 10.13
macOS 10.13 High Sierra introduces additional security changes which prevent normal applications from accessing the current startup drive’s raw contents.
This change, which is an expansion of the existing System Integrity Protection feature introduced in macOS 10.11 El Capitan, prevents some parts of Drive Genius from functioning correctly, such as Physical Check, Repartition, Clone, Secure Erase, Speed, and Defragment.
In addition, the new Apple File System (APFS) requires many Drive Genius utilities to be updated in non-trivial ways for the new filesystem.
