Good morning Kathy

Yes, I did all that exactly as written on your instructions page and the installation went exactly as described. No problems. And the firewall is turned off.

Now, on my screen top bar on the right hand side, I have the Mac wi fi icon showing next to the TP-Link icon.

The TP-Link has a line through it. When I click on the icon, I see a single drop-down message in grey: "No Wireless NIC plug-in"

Then a pop-up window opens automatically, that says: "system software from developer TP-Link Technologies Co, Ltd was blocked from loading".

So I open system preferences / privacy, unlock the changes, and click on "allow", but nothing happens.

I have tried uninstalling and reinstalling from fresh, but there is no difference. The Mac will not allow the TP-Link system plug-in to load.

What is the solution?

Best regards

Andrew

Hi Kathy

Thank you for trying to sort out the problem of the Mac rejecting the TP-Link system extension. I appreciate your work.

Your link leads to a Chinese language blog that I cannot read! But I can see that the blog is talking about using Terminal to bypass the security system. I have seen this in other western blogs, but I am not particularly happy about using Terminal to alter the Mac OS, when the TP-Link software should, in fact, be an easy install.

So I decided to return the T2U to Amazon and I will look out for a product where the software is properly compatible with Mac. If TP-Link make a similar product where the software is known to work, I would be glad to hear about it. I'm in no hurry.

Again, many thanks for your efforts

Best regards

Andrew
