I'm running Windows 10 in Parallels on my brand new 2017 Macbook Pro. While at work, I have two attached monitors and an old clicky Windows keyboard.
The problem is that I can't get Parallels to accept the higher function keys. F5 works, but not F11, which is very critical to a .Net developer.
I'm adding the Touchbar Tag because I'm honestly not sure if Touchbar settings are causing this issue. This is an upgrade and I use to not have this issue on my four year old Macbook Pro. It's inaccessible, so I can't check the settings, but I don't remember this being as big an issue.
