The changes that Apple made in Mac OS 10.11 disabled the functionality of our secure USB drives. This causes the error "Unable to start the DTXX application..." or "ERR_COULD_NOT_START" when you attempt to log in to the drive. We recommend that you update your Kingston secure USB drive by downloading and installing one of the updates provided in the links below.

The Windows-based update utilities will work on the following Windows versions (Windows Vista SP2, Windows 7 SP1, Windows 8/8.1 and Windows 10). You must have administrator rights on the Windows-based system.

The Mac OS update utilities will work in Mac OS 10.10 and up.

This update will format the drive and all user data will be lost! Please back up your data on another compatible system before proceeding with this update. Once the drive is updated, it will work with Mac OS 10.11 and other previously supported operating systems.

Detailed instructions are included with the download.
