Just don’t buy it.
This very expensive keyboard promises a lot but delivers a lot of frustrations instead.
This keyboard is intended for people who use both Mac OS and Windows. It offers keys for both operating systems, and many keys are shared. These shared keys have symbols on the left side for Mac and the right side for Windows.
On top of that, you have a dial that allows you to do some cool things with it when rotating or/and pressing it. But the possibilities are limited. We use it to switch workspaces when rotated and set it to “paste” when pressed. This way we finally have a keyboard with a dedicated paste button. We copy and paste a lot when coding.
When it launched, a lot of keys like the Home, Insert and End keys simply did not work as expected. Not on Mac, and not even on Windows. A few updates later, and things begin to work, but it is still not a hundred percent ok.
Update: the latest updates released in April 2019 finally seem to resolve some issues for some people but not for us. ALT and CMD are still reversed in Mac OS. If we correct that using system preferences, we still get the problems in Windows as described below. We managed to get a working situation in Windows if we leave the Mac keys reversed, but it is still impossible to get a pipeline character in Windows running in Parallels on Mac for example.
Update 2: Update released in October 2019 made a mess again. The <> and @# keys are now suddenly switched in both Mac OS and Windows. The insert key no longer works. You now need to press 2 modifier keys (alt+ctrl) to get AltGr if you need things like @ in Windows. This is like most normal Windows keyboards function when connected to a Mac. No need to buy this expensive crap keyboard for that. With each update, we have to learn all the workarounds again. The good part is that the pipeline symbol now finally works for us. Reverting back to an older version did not solve these problems. Logitech please fix this shit. When will this keyboard function as promised?
If you use it solely on a Mac, or solely on a Windows machine, you can get things to work for the most part. Switching between machines is easy with the dedicated connection buttons.
But if you are going to use this for Windows running on a Mac, using Parallels or VMware Fusion, you will have more problems. Even after many months and many updates, it is still not working as it should. On Mac OS, the CMD and Option keys are reversed. You need to correct that using the keyboard preferences of Mac OS. If you do that, however, in Windows the right Alt/GR simply will no longer work. You need to use the left Alt key, which now always gives you Alt GR, so just using Alt is impossible. Forget about pressing key combinations like Alt F4. Typing a pipeline symbol is impossible. If you do any development, that is a big problem. Many special characters require you to simply press the wrong modifier button to access them. So you better leave the reversed CMD and Option. Windows is usable then, except for the pipeline symbol. That is still impossible. We use Alt+124 to get it, like in the old DOS days.
With every update, some things are fixed, but other problems arise. The keyboard always seems to behave in a different way that requires you to start looking for workarounds. It depends on the keyboard layout that you select in Windows. And different people also report different issues, even if they are running the same software version.
At this price point, this is inexcusable. Stay away from this keyboard, unless you really want the rotating dial, and are prepared for these issues.
In the meantime, we keep using it. We got used to the issues, and hope one day they will really be fixed. But we still regret paying that much money for a keyboard that can not do the basics right.
Update 3: January 2020. We moved away from Mac and are using the keyboard on a pure Windows 10 machine. Some issues remain, however. The Insert key is not working at all (we use Shift+0 for that now), and two keys on the keyboard (<> and ²³) are reversed, keys like AltGr and the Windows key are also under the wrong keyboard buttons. Logitech Options keeps bugging us about updates but each time we agree to install them it just says we already have the latest version. We had to disable notifications for the Logitech Options app to get rid of these annoying messages. This product should never have been released, and yet they are still selling it…
May 2020: Thanks to the new keyboard mapping feature of Microsoft Powertoys we were able to correct some of the wrong key mappings of this keyboard. We cannot correct everything however. If we pair the Windows key with the button the is labeled “Start” and move Alt to the button that is labeled accordingly, it is no longer possible to switch desktops using the dial or the knobs on the Logitech MX Master mouse. So, we have to leave this. Thinking about just switching the physical keys on the keyboard. Insert key still not working. Does nothing when pressed. We can still not believe how Logitech is not able to make this keyboard work as intended.
Update 4: June 2020. We received an update that finally makes everything works correctly in Windows. All keys seems to be mapped correctly and even the Insert key works again. We don’t know how it will be on Mac OS now because we stopped using Mac’s.
