I use German keyboard settings (QWERTZ). I have Rotate assigned to Y. In Windows, this works correctly by pressing the key with the printed Y on it (lower left). In OSX however, Y and Z are mixed up (in Factorio), so I need to assign Rotate to Z in order to have it work with the Y key.
Normally, this wouldn't be a big deal, but since I play on both Windows and OSX, I have to reassign the keys every time I switch from one OS to the other, as these settings are synced over Steam Cloud Sync. Probably applies to older versions than 0.15.9 as well.

Re: [HanziQ] [0.15.9] Keyboard Regional Settings Mac not working
Since we're removing Allegro for 0.17, and all input related things will change, we'll handle it then.

In 0.17, we have changed how this works, so it should be resolved.
