Microsoft Sculpt Keyboard doesn't work on macOS Sierra
I don't know about your Macbook, but I got it to work with a late 2016 Macbook Pro with an adapter to go from the USB-C ports to the traditional Type-A USB-Ports. (Hyperdrive by Sanho) So far the Microsoft Sculpt works very well. (Some of the PC-only Fn keys don't work e.g. the search button, but it's not a major issue)
I used Karabiner Elements to change the key assignment a bit. I can recommend this guide: https://www.themtparty.com/archives/6286
