Yes, this keyboard also works with a Windows system. You can switch seamlessly between the systems. So from Mac to Windows and vice versa. This function is called Logitech Flow. You can pair 3 computers and then switch between them.

The keyboard works very well with the Mac. Exception: after system updates or crashes, the keyboard is often not recognised when booting, so the only thing that helps is to briefly use a cable keyboard. As far as Windows is concerned, I only have Parallels with Win 10 running, which works without any problems.
