Error Message "DisplayLink driver can't be installed on this disk. isDowngrade" seen on installation

← Troubleshooting: macOS
If you see the message: "DisplayLink driver can't be installed on this disk. isDowngrade" when trying to install, this is usually because the DisplayLink driver is already installed and you are trying to install the same or older driver over the top.



If you are trying to install the DisplayLink driver, try uninstalling first. If you are trying to install again because it did not seem to be working, check the DisplayLink device is detected on the USB bus and the DisplayLink kernel extension is enabled.
