Genius external keyboard working improperly on Macbook Pro I want to use this Genius keyboard with my 2014 MacBook Pro 15". 

When connecting the keyboard, the Keyboard Setup Assistant opens, saying that keyboard could not be identified. Then, it asks to press the key on the left of right shift. When I press 'Z' key three times, it says that the keyboard still could not be identified and asks to chose the type of keyboard manually. 

Despite of the answer, keyboard starts working improperly. When I press 'q' it types 'x', 'w' -> '4', 'e' ->'l', 'r' -> 'y', 't' -> '1', 'y' - '6' and so on. When I chose different type of keyboard (ISO/ANSI) nothing changes and the same wrong buttons mapping preserves.

The keyboard itself is working fine on other PC.

Would really appreciate your help to make it work.
The behavior sounds like a Num Lock or Fn key is stuck on. Does the keyboard behave this way on a PC without the Genius keyboard driver installed?

I don't know how much effort you want to put into this, but Karabiner is a general-purpose tool for remapping just about anything about a keyboard attached to a Mac. You can make rules which only affect a single device. How much do you like this keyboard?
