iMac not seeing 5GHz Wi-Fi on macOS, but everything's fine on Windows
I have an iMac 27 mid 2011. The OSes that I have are Sierra and Windows 8.1 (via Boot Camp).
When I open the Wi-Fi menu on macOS, it doesn't show me any 5GHz networks, but when I boot into Windows, it works fine. When I try to connect manually (as if there was a hidden SSID), it fails to connect.
This clearly isn't a hardware problem (since Windows has no issues with 5GHz Wi-Fi), so I wonder if anyone has expected similar stuff on their devices.
P.S. I had to choose "iMac Line (2012 and Later)" as device because there wasn't a choice for older iMacs
