Well...I'm sorry to tell you, and happy for myself...but with the Wifi card installed, I have BT and Wifi in OSX, didn't change anything, just installed and booted. Booted into Windows 10 too, and it worked as well. I guess it takes long term usage in Win10 to detect problems there, but initial usage seemed to be OK with some quick checks. I won't be using Win10 accept for occasional gaming, so I may never notice the issues.
Sleep works too. So when I get time, my remainign thing is the iMessage stuff needs to be done. But otherwise I am 100% functional.
