    Hi, Is anyone else experiencing problems switching their WiFi on after updating to the latest 10.10? The WiFi button does nothing on my 2013 Mac Pro - Thanks

    Yep, I had the same problem. I did several things all at once and one of them fixed the issue; unfortunately I don't know which was the magic bullet:

    -deleted the network-related configuration and preference files
    -unloaded/reloaded the "discoveryd" service
    -removed all of my preferred Wi-Fi networks and added back only the one I currently use
    -removed/re-added the Wi-Fi service in the Network preference pane
    -reset PRAM and SMC
