"Edimax Yosemite compatible drivers available for EW-7711MAC (AC450)
Saw the update yesterday. Installed and the AC450 now works fine under Yosemite.
(I asked if he was running OS X 10.10.2, as driver notes 10.10.1)
I have it installed on a 2009 Mac mini running OS X 10.10.2. It is connected to the latest generation Airport Extreme at 5GHz. I ran a cable modem speed test on it and it was right at my max throughput of 60Mbps down and 4Mbps up. Haven't tested file transfer speed between it and another Mac yet. No problems so far, but I'm not a fan of the software. Puts an unsightly bar graph in the menu bar and I haven't found a way to hide it.
