Network wifi adaptor that works with MacOS X 10.12 Sierra?

According to http://www.tp-link.com/us/download/TL-WN722N.html#Driver the latest driver listed supports El Capitan aka 10.11.

I don't have this product so cannot comment on it specifically, but in general if a drivers exists for El Capitan it means it is a driver that should in theory be 'signed' so as to pass the SIP security. As such there is a much better chance the same driver would work on Sierra as well which also uses SIP security.

See https://support.apple.com/en-gb/HT204899

It is also possible to disable SIP protection and this often then allows older unsigned drivers to work even with newer operating system versions. See this article for instructions on how to disable SIP http://ntfs-formac.com/how-to-disable-sip-rootless-system-integrity-protection/

I bought TP-Link TL-WN823N Adaptor and tried to install with the drivers that came in CD. It did not work for MACOS Sierra version 10.12.2 on Macbook Air

When I contacted TP link online support they gave me a link that current drivers support versions only upto 10.11 for which driver is available at http://www.tp-link.in/download/TL-WN823N_V1.html#Driver

When I downloaded the driver from the above link it installed perfectly and Adaptor TL-WN823N is working great with MacOS Sierra 10.12.2

Actually speed is faster than the original Macbook Air wifi You can also try and get the solution

I am at 10.2.3 and tried to install the beta version. I have uninstalled both the EDIMAX driver and the TP-Link beta driver and then I installed the beta version again. When I click on the Utility to configure the new usb wifi device it says no NIC plugged in.

Well I have not upgraded from 10.12.2 fearing any other compatibility issue.

Last when I upgraded from EI Capitan to Mac OS Sierra, the original wi fi of the Macbook Air started behaving crazy. Now using this TP-Link TL-WN823N Adaptor and the it is working perfectly great till now. Touchwood !

Thanks... We tested it today with a MacBook Pro 2015 and a Mac Pro without any problem in Sierra 10.12.3
Seems that this device is incompatible with the MacBook Air 2014, where I need a dongle because the Airport system is dead.

I need to find another USB device but I don't know which one

Just placed an order for the TP-Link TL-WN823N. Fingers crossed that it will work. I had a MonoPrice dongle that worked on my PC, but could not get it functioning on Sierra. I need two NICs, one for the regular internet, the other to connect to a drone. The idea is that I'll be able to allow people to control the drone over the internet if I get this working. I'll let you know how it goes.

Side question: why are Apple's operating systems not backwards compatible drivers of previous years? I am not trying to open a discussion as to why one OS is better than the other and I hate comparing the Apple's OS to Windows... but a driver works on Windows 7, it typically works on Windows 10.

Thanks!!

It is true that most Windows 7 programs and drivers work in Windows 10 but not all.

It is also true that many older drivers do not work in El Capitan or Sierra.

One of the main reasons is that with El Capitan Apple introduce an additional security feature called 'SIP' aka System Integrity Protection. This feature requires drivers be officially signed by a valid developer certificate to prove they are genuine and trusted and not malware. It also makes it easier to block such software by revoking the certificate if needed and SIP also prevents modifications to locations that belong to the operating system.

There are ways however to turn SIP off and this can actually allow older drivers to then work. Obviously it is much preferred for the developer of the driver to issue a new properly 'signed' driver. The problem has been that manufacturers have either disappeared, or decided not to issue new drivers for obsolete hardware.

Which version of TL-WN823N are you using?

I have a V2 and it is not even detected in two MacBook Air 2014 :-(

V2

The TP-Link TL-WN823N arrived today. $10 used on Amazon. With the driver install recommended above it works work perfectly. Thanks for the suggestion.
