I’m running macOS High Sierra (10.13.2) my Mac Mini (2012) and MacBook Air (2013) I just purchased an Edimax EW-7811UN USB Wi-Fi adapter to use on my MacBook Air but for some reason—even with the correct drivers installed—the OS doesn’t seem to recognize it.
It’s clearly recognized as a USB device with the correct system report information on the Mac Mini as well as the MacBook Air. But if I install the correct drivers on both systems, it only actually works on my Mac Mini. The MacBook Air? Nope. The driver I am using is the macOS Sierra (10.12) drives I found on the official Edimax website and the “README” shows it as version 1027.4.02042015 which was released on “2016-12-20” which is pretty much a year ago.
Anyone run into this issue before? The USB 3.0 ports on my MacBook Air work 100% fine with other devices. What could be up? Details from my system profiler below:
