This article provides instructions to enable kernel extensions that have been blocked during software installations in macOS.
Apple introduces a new security mechanism in macOS High Sierra 10.13 that requires a user’s approval before loading third-party kernel extensions (kexts). Several LaCie programs are impacted by this macOS feature. Please see below for the list of impacted applications:

Note: The macOS alert message shows the name of the developer who signed the KEXT, which comes from the Subject Common Name field of the Developer ID Application certificate used to sign the KEXT.
When installing software on High Sierra you may receive an alert message “System Extension Blocked” see image below:
Click OK, then proceed to Security & Privacy to enable the kernel extension in order to complete the installation.
Note: It’s important to know that once you press OK, you have 30 minutes to approve the software.
See Instructions to enable blocked software:
For macOS 13 (Ventura) and later
For macOS 12 (Monterey) and earlier
If the System software is not listed under the general tab of macOS Security and Privacy, it’s recommended to reinstall the software and immediately proceed with the steps 1 to 5.
