Linksys specified its driver to work up to OS X 10.9. The orignal driver doesn't work with my 10.11.5 and Linksys really helping. However, there a few helpful tips (alternative drivers) in this thread: https://community.linksys.com/t5...

Not with the drivers provided by Linksys. But you can install the driver from Realtek (the manufacturer of the chipset): http://www.realtek.com.tw/downloads...

I think so, I installed it on Mojave (10.14.6)
