Well, I installed Windows 10 yesterday on my 15-inch retina MacBook Pro, early 2013 model. I used Windows 8.1 on my BootCamp partition which I shared with Parallels, and I upgraded it to Windows 10. Now, Windows 10 seems to be working fine, except for wi-fi which is simply not working, neither under BootCamp nor Parallels. Is anybody else experiencing this? Is there a fix for it? Thanks for any help you could provide.
