I downloaded it, installed it and rebooted my machine: the Logitech Control Center icon did appear in System Preferences, but my mouse did not show up and no matter what I did, clicking the Open Unifying Software button made the application crash (which was a bummer since my mouse obviously needed to be paired with the dongle again). I made a quick search online and everything seemed to point to the same piece of software, the Logitech Control Center. I inserted some batteries, plugged the dongle and switched the mouse on: nothing. I found it among old RJ45 cables and dusty keyboards: a Logitech Anywhere Mouse MX, using the Unifying technology - basically a tiny dongle to plug to one of the machine's USB ports, and supporting devices of the same product range. I decided I would get one for my personal use as well, and first peeked at Apple's horrendously (and unsurprisingly) expensive Magic Mouse, before I remembered that once upon a time I had a wireless mouse, when I was still a Windows user. Having worked with a Magic Trackpad (version 1) for a while, then with a mouse again for one of my contracts, I realised I actually felt more comfortable using the latter.

This post is mainly for my own future reference, but if you are running into the same kind of troubles, hopefully following the quick steps below will help.

In my case it was the latter, and it took me a ridiculous amount of time to find a solution, mostly because of borked software. The cordless Logitech Unifying devices can be a bit funny when it comes to MacOS Sierra, be it the scrolling acting weird or the device not being detected altogether.
