The issue is connected with SIP (System Integrity Protection) security technology. If you want to use Folder Actions for FineReader Pro, you can try to disable SIP as described below:
- Turn off your Mac (Apple > Shut Down).
- Hold down Command-R and press the Power button. Keep holding Command-R until the Apple logo appears.
- Wait for OS X to boot into the OS X Utilities window.
- Choose Utilities > Terminal.
- Enter csrutil disable.
- Enter reboot.
Your Mac will reboot and start up with SIP disabled.
To enable SIP proceed the steps 1-4 above again and at the step 5 enter csrutil enable.
