The current version of SoftRAID is fully compatible with macOS High Sierra 10.13

The current version of SoftRAID has been extensively tested and is fully compatible with macOS High Sierra 10.13. Please note that the current version of SoftRAID does not support creating, modifying, or converting APFS volumes. However, SoftRAID’s certify, verify, and monitoring features will work with APFS formatted disks, and the current version of SoftRAID works exactly as before with non-APFS formatted disks—in some cases better, since this version includes several optimizations.

IMPORTANT! If you’re a SoftRAID user, please follow these steps to upgrade to macOS High Sierra 10.13:

  1. Disconnect ALL disks which are formatted with SoftRAID
  2. Download and run the High Sierra Installer to upgrade Mac OS
  3. Launch the SoftRAID application and select Check for Updates under the SoftRAID menu
  4. Run the new, latest, version of SoftRAID you’ve just downloaded and let the application update the SoftRAID driver
  5. Reconnect your disks formatted with SoftRAID

SoftRAID 6.0 beta

SoftRAID 6.0 will be fully compatible with APFS disks and volumes. You’ll be able to create and manage APFS volumes and SoftRAID 6.0 will also offer extra functionality to allow you to further manipulate APFS volumes. At the same time you’ll still get all SoftRAID’s great existing functionality, whether you’re working with APFS or HFS formatted disks.

SoftRAID versions before 5.6.3 not compatible with macOS High Sierra 10.13

SoftRAID versions prior to 5.6.3 are not compatible with macOS High Sierra 10.13. If you plan on using High Sierra, it is best to upgrade to the current version of SoftRAID (and crucial that you do NOT try to use any version of SoftRAID prior to 5.6.3) using the steps outlined above. Failure to do so may result in kernel panics.

  • The macOS High Sierra Installer does not recognize SoftRAID volumes as valid startup volumes. If you want to create a macOS High Sierra 10.13 startup volume using a SoftRAID volume, please follow the steps shown on this forum page.
  • All SoftRAID volumes fully support TRIM on Apple and non-Apple SSDs. If you are using SSDs and wish to enable TRIM for non-Apple SSDs, you must instruct macOS that it is safe to use TRIM on your SSDs.
    For macOS High Sierra 10.13, you can use the trimforce command in a Terminal window to enable TRIM on these SSDs. For a more detailed description of TRIM on macOS, please see the ArsTechnica article.
