Years later I still rue the day I bought my Logitech mouse and keyboard as this app is just so unbelievably **** on a mac it ruins the whole experience. The devices constantly forget the custom key mapping and recently the app creates multiple logicrashpadhandler processes using up 100% of a cpu, making this M1 mac hotter than it's ever been and these are unable to be force quit. If you are on a mac I 100% recommend do not purchase any logitech products - they just don't seem to give a **** about the mac platform
