[Macha]

This is just marketing guff. What it means is there's a toggle on the side between Mac and windows keycodes so you don't get command moving places when you use it with a Mac like a regular windows keyboard, and it ships with the Mac keycaps installed.

You can swap out the Mac keycaps for windows keycaps (at least when I got it all, the windows keycaps were all in the box) and flick the switch to the windows position and it's a standard PC keyboard.

Mine is actually my Mac keyboard (I've got a ducky shine connected for my personal Linux/Windows dual boot machine as it's easier than fiddling with a KVM or synergy), but I've got it configured as a windows keyboard as I've just been using windows keyboards with macs for like a decade now.
