Apple Mac OS 11: Big Sur Compatibility News for ALFA AWUS036ACH and other products

November 12, 2020

(EDIT March 24, 2021, we have a NEW UPDATE about Big Sur. Click Here to read this information that is newer than what is posted below).

If you already own an ALFA 802.11ac USB WiFi booster and have followed our steps to get it to work on Mac OS 10.15 Catalina, you may be wondering if you upgrade to Big Sur (released by Apple today, November 12th), if your product will still work after the update. Operating system upgrades can often times break hardware.

The good news is we have tested it today and can confirm with the 11.0.1 release the ALFA AWUS036AC and AWUS036ACH still work well.

We have not yet confirmed if you can do a new install the same way you can on Catalina. So if you do not yet own an ALFA AWUS036ACH and are looking to get one and install it on Big Sur, we have not yet confirmed the installer will work. We should have an update on that in the next few days and will post to our blog.

I just bought an Alfa AWUS1900 USB adapter. It keeps showing that The Installation Fail when installing the driver to my Macbook Pro with the macOS Big Sur 11.0.1.

Can you give me advice how to install the driver please?
Thank you

The AWUS1900 & AWUS0336AC* series are not currently compatible with Big Sur new installations. We do not have an ETA on if/when a new installer will be released for Big Sur.

Karmen said:

Any news for the AWUS036ACH or AWUS1900 for MacOS Big Sur? What’s about the ALFA team? I did not contacted them, but they should have a solution.

Please let us know when the driver is available soon.

Here is a workaround option for Big Sur. Please read the full article and understand that this driver workaround was not test by ALFA. said:

it’s sad to see people not even reading the article properly because it works very well
The link is in the first line of the article

This update is not official, and you need to disable some MAC safety functions.

Looking for Big Sur support for AWUS036ACH . Currently there is just 10.14 MacOs drivers available.

@Rokland – that is not for Realtek chipset. Any updates about mediatek?
