Live Chat (opens in new window)Starting in High Sierra 10.13, macOS enforces stricter security policies than previous revisions. As a result of these changes, software packages, like those used in this installation, will need to be allowed within the macOS Security and Privacy settings, immediately after the software has been installed, in order for the device to operate.
To allow the software, follow these steps after you've completed installation on your Mac:
Note: The option to allow the software will be available within the Security & Privacy settings for 30 minutes. If the software is not allowed within that time frame, the software must be reinstalled in order for macOS to grant the opportunity to allow it again.
Some driver installation packages may require you to disable driver signature enforcement in Windows 8, which will allow unsigned driver packages to be installed on your system.
Note: Before you continue, save any open documents and close all open programs.
To disable driver signature enforcement, complete the following:
When your system finishes restarting, complete the following:
When your computer restarts, driver signature enforcement will be disabled and you can install your drivers.
Note: When you restart your computer after you install your drivers, driver signature enforcement will be enabled again. This does not prevent your newly installed drivers from working, but does prevent any other unsigned drivers from being installed until driver signature enforcement is disabled.
Some driver installation packages may require you to disable driver signature enforcement in Windows 8.1, which will allow unsigned driver packages to be installed on your system.
Note: Before you continue, save any open documents and close all open programs.

Older applications that use serial communication often use legacy hardware addresses that do not work with PCI, PCIe, or USB to Serial products. We recommend contacting the software provider/support team to check if this is the case.
If the USB device does not work after your computer has been in extended hibernation, it is likely that Windows has automatically turned off the USB Root hub to save power.
The steps below outline how to configure the USB root hub to stay on during hibernation, to prevent this from happening.
