Like the mouse, the Mac version of the MX Keys is mostly an aesthetic change. That’s odd, because the MX Master 3 for Mac definitely still works with Logitech’s Unifying Retriever, and that’s exactly how I had it set up, using the USB dongle that shipped with the MX Master Keys for Mac. In terms of major differences, the main one any owners of the MX Master 3 will notice is that the MX Master 3 for Mac is listed on Logitech’s website as only offering Bluetooth connectivity - and it doesn’t ship with Logitech’s Unifying USB receiver, which connects its peripherals via a dedicated RF network instead of Bluetooth for greater reliability. The mouse uses Logitech’s Darkfield laser tracking, which provides 1000 dpi on average of accuracy and the ability to track on virtually every surface, and it can also work across Macs and iPads with Logitech’s Easy-Switch technology for connecting to multiple devices. It can run for 70 days on a full charge, and you can get three full hours of use out of just 60 seconds of charge time. The MX Master 3 for Mac ships with a USB-C to USB-C cord in the box instead of the USB-A to USB-C cable that comes with the non-Mac version, and that’s much more convenient for charging and using it dongle-free with modern MacBook computers.
