Hello, 

I think I have the same Issue. 

I am running MacOSX Mojave 10.14.4 and have TP-WN823N V2 USB Wifi. 

I get following error messages when starting the StatusBarApp in the terminal: 

$ sudo ./StatusBarApp

I think there is a problem either with APFS file system or something similar.

Hi, 

even if I have the TL-WN823N V2 Wifi, I had to install the latest TL-WN823N V3 driver. With the V3 driver my V2 version worked. 

Best regards, 

Fox

I experience the same problem running TP-LInk AC600 with driver V3 on MacOS 10.14.3.

It shows No Wireless NIC plug in.

Can anyone give suggestions to solve the problem?

I have also tried driver V2. The system shows connected, but there is no connection. I have updated to V3. However, it is getting worse.

my Archer T2U Nano V1 does not work on MacOS 10.14.3 too....

I’ve been using the TL-WN725N version 1 WiFi driver. Recently macOS was updated to macOS BigSur and since then the driver is not working.

Hello have you guys found the way to make this TL-WN725N to work on MAC OS Big Sur System yet...? before I take your option below, please advise...thanks.
