I have an MX Master mouse (latest version) with Logitech Options (also latest). The mouse is bluetooth and have 3 switches, allowing you to use the mouse with 3 different devices (Mac, Windows, Android, etc.). It was working just fine on MacBook Pro 13" and MacBook Air, both with Yosemite. I can press switch 1 for MBP 13" and switch 2 for MBA. I have another MacBook Pro 15" that I upgraded from El Capitan to macOS Sierra. I tried to add MX Master to this MacBook Pro but it could NOT find the mouse. I tried rebooting the machines, turn off/on bluetooth and reset the mouse, but to no avail. Anyone have issue adding bluetooth mouse or this particular model (MX Master) to computer upgraded to macOS Sierra?
