Archer T3U "No Wireless NIC plug-in"
Model:
Adapter
Hardware Version: V1
Firmware Version: 5.0.8.b5
On a MacBook/OSX 10.11 the Archer T3U installed and works fine. However, the same adapter when installed on a MacBook Air/OSX 10.14, the installation produced no reported error, but failed to activate. Downloaded the latest driver directly from TP-Link < TP-Link_Archer T3U_V1_190402_Mac.zip > The icon text is in grey: "No Wireless NIC plug-in". Clicking on the icon a pop-up window opens automatically, that says: "system extension blocked from loading". No firewall activated. Opening system preferences / privacy, unlock the changes, and click on "allow", but nothing happens. Reinstalling makes no difference. The Mac will not allow the TP-Link system plug-in to load.¿?
