Gatekeeper.
There is one extension I need gatekeeper to ask me again as last time it asked me but I didn't go to System Preference to allow it. Now I cannot allow it anymore... Any help?
Have you tried restarting the computer?
After restarting the computer try running the app associated with the driver to see if triggers Gatekeeper to prompt you for permission to run. I had this issue with an Intel app which included a driver. After a couple attempts to get a Gatekeeper prompt the app & driver just worked.
If this doesn't help, then you will most likely need to contact the developer of the app/driver.
Make sure you are not running any anti-virus software, cleaning apps, or third party security software as they may interfere with the app and driver.
