I have noticed on my current Mac builds that if I bind "left shift" or "right shift" Unity behaves as if I have hit both shift keys whenever either is hit. I'm using the smaller Mac keyboard.

Specifically, if I put in this code:

        if (Input.GetKeyDown(KeyCode.LeftShift)) {
        Debug.Log("Left Shift");
    }

    if (Input.GetKeyDown(KeyCode.RightShift)) {
        Debug.Log("Right Shift");
    }       

Unity console will return both "Left Shift" and "Right Shift" each time the key is pressed. This also happens if I specifically bind the "left shift" and "right shift" keys to an input in the Input Manager.

If I build this same project to PC, the shift keys are correctly differentiated.

Anyone have an idea of a workaround for this? I'm working on a pinball game and it's fairly universal that you use the two shift keys for the flippers.

EDIT: Well, I just got an e-mail back from Unity QA and they say this is working as designed since Mac doesn't send different commands for each key. I beg to differ since I've seen games that support both keys. However this might be a limitation based on how Unity polls for keys.
