Sep 04, 2017 Gatekeeper, first introduced in OS X Mountain Lion, is a Mac security feature which prevents the user from launching potentially harmful applications.In macOS Sierra, however, Apple made some important changes to Gatekeeper that seemingly limit the choices of power users. But don’t worry, Gatekeeper can still be disabled in Sierra.

Firewall: Mac OS X includes a built-in firewall, which you can enable from this pane. To turn the firewall off entirely, simply click the Stop button. Any Mac hooked up to a network or the Internet should have the system firewall turned on. Using the Terminal is the best way to allow installation of applications on your Mac without the tedious process involved in making exceptions for each one of them. Using this method, you can install and use applications as you wish regardless of their source. Opening apps from unidentified developers are not for. Jul 25, 2012 Use –master-enable to enable Gatekeeper: spctl -master-enable And then use –master-disable to disable Gatekeeper: spctl -master-disable Whether Gatekeeper (assessments) is enabled or disabled can be returned using the –status option: spctl -status The -a option is used to assess an application to see if it will open or not: spctl -a.
In our recent post titled macOS 10.13 High Sierra Significantly Improves DisplayLink Performance & Stability we talked about how the latest update to macOS improved behavior when using a DisplayLink product (such as the Plugable UD-ULTCDL docking station). To go with that, we wanted to take a moment to discuss the Gatekeeper security feature introduced back in OS X 10.7 which has gone through some changes in High Sierra that may affect installation of some 3rd party device drivers used in devices from Plugable and other device manufacturers. For Plugable, the issue will only impact our products which don’t have drivers already built-in to macOS, such as our USB Docking Stations, USB Graphics Adapters, and USB Ethernet Adapters. Essentially this issue can affect any extensions not developed by Apple. Thankfully if you encounter this, there’s a simple process to fix. Keep reading for additional information and instructions.
In macOS 10.13 High Sierra, when installing new software and extensions, Gatekeeper now requires users to manually approve any new third-party extension before the computer can load and make use of the extension that was installed. This is important as many devices rely on extensions to function properly, and in some circumstances it can look like the software to power a device was installed but the device still doesn’t work. When this happens, users will see the below message:
If you suspect Gatekeeper is preventing an extension from loading, follow the below steps:
- Open System Preferences and navigate to the Security & Privacy section.
- In the General tab, look for a message at the bottom of the window stating “System software from developer DEVELOPER NAME was blocked from loading”, like in the screenshot below:
For Plugable products, the developer listed in the message should be “DisplayLink Corp” for DisplayLink powered products (such as docking stations that do not use Thunderbolt 3 technology) and “WEI LU SU” for Plugable ethernet adapters that use ASIX chipsets (as of the time of writing this, all Plugable USB network adapters use ASIX chipsets). - Click Allow, and from there macOS should now be able to properly load and use the extensions and software that were installed.
- Test things out! In some instances, you may need to restart the computer for the extension to properly load. So if it doesn’t work immediately, reboot the computer and the extension should load correctly.
Once an extension from a developer has been allowed, this makes the developer a ‘trusted’ source. Meaning that future extensions that are installed from the same developer should not be prevented by Gatekeeper from loading and should not need to have these steps repeated. However, software and extensions from other developers will encounter this same issue and you will need to follow these same steps.

Unfortunately, due to changes in macOS 10.15 Catalina and support for third-party drivers, we are unable to continue support for macOS with our ASIX USB to Ethernet adapters (USB3-E1000, USBC-E1000, USB2-E1000, USB2-E100, USB2-OTGE100). Our USB3-HUB3ME and future USB to Ethernet adapters will use Realtek based chipsets that utilize drivers built into macOS.
