ASUS USB WiFi adapter not working on macOS due to driver issue (Cause and how to solve it)

If you have an ASUS WiFi USB adapter, it should be working flawlessly on Windows computer. However, when you want to use it on macOS, it is not that simple.

A driver is needed before using an ASUS wireless USB-A adapter. It is because, macOS does not come with a compatible Realtek wireless network driver.

If you are using a Macbook with macOS version outside 10.7-10.14, you are probably unable to install the official driver provided by ASUS.

With that said, I tried to install the official driver on a 2012 Macbook with macOS Big Sur and still not managed to do so.

Therefore, the only way is to install unofficial driver.

The unofficial driver I installed is developed by chris1111 and extremegrief1, released on Github. It supports every version of macOS since Big Sur.

Following the instruction and video guide, my ASUS USB-AC53 nano is able to work on my MacBook without trouble!
