Blackwidow Lite - on MACOS and german

Hello fellow friends, I want to buy the blackwidow lite mercury and the razer basilisk. I have 2 very big problems first im German and need a german layout for work. Second I mainly use macos. Is it possible to use the mouse and the keyboard on mac. I dont need macros or fancy lighting settings. What I need is one profile whereI bind the keys so it matches the German keyboard layout. I read that it is possible to create a profile on windows and save it on the keyboard. Can you comfirm? Would be awesome if you could help with my questions. Love razer <3
