I have using this with my Macboook Pro 2017 and it works like a charm. There are no lags what so ever. Great for watching video on your TV or attaching a monitor. Specifically for gaming, I did notice a drop in FPS across various games. Also, I didn't realize that if I connect this and my gaming mouse, I won't be able to charge my laptop. So overall if you use a wired mouse/ wired keyboard with your Macbook may be this is not the best option for you.
