The menubar icon is related to StatusBarApp.app
Possible paths:
/System/Library/CoreServices/StatusBarApp.app
# for version 5.0 (2016) on Mojave
/Library/Application\ Support/WLAN/StatusBarApp.app/
You can close the app by killing the process via the Activity Monitor
mac app or entering:
killall StatusBarApp
Note: The app will still open next time you restart the Mac
The app is loaded by launchd
while booting. The related plist should be located at /Library/LaunchAgents/
and the file name is Wlan.Software.plist
.
To unload the launch agent enter
sudo launchctl unload Wlan.Software
To permanently remove the launch agent enter
sudo launchctl remove Wlan.Software
Alternatively you can remove the file /Library/LaunchAgents/Wlan.Software.plist
.
After a reboot the icon should be gone.
I have tested this with the installer TL-WN725N_V2_150901
. Since you didn't specify any adapter (or driver) in your question the name of your app/plist may differ. Please check this with launchctl list
or launchctl list | grep -i wlan
.
