RK ROYAL KLUDGETypewriter Mechanical Gaming Keyboard with Rainbow RGB Backlight & Sidelight, Retro Punk Round Keycaps, and Removable Wrist Rest

Can you completely turn off all the lights, including the lights on the sides?

Is there a way to turn off the clicking sound, or is there a different but similar model as the white without the clicking noise?

How do I get replacement keycaps and the rings around them?

I tried using with my Mac and It doesn't seem to be compatible. I need to unplug and plug back in whenever I turn my Mac on. Is there a remedy?
