Questions about BlackWidow V3 Pro and Razer Naga Pro

Hello everybody! i am browsing the market to buy a new set of keyboard and mouse with a set of particular requirements.after research, it seems that the BlackWidow V3 Pro and Razer Naga Pro fit the bill: - dual connectivity - i intend to use them on my personal PC and work Mac - a high number of mouse buttons - i have a lot of actions set to my mouse button that i frequently use and at the moment i am limited to 3 (i have 2 side buttons too, but those are back and forward for browsing) - iluminated keyboard - this doesn't have to be RGB, i'm used to white - media controls - wrist pad/rest Would have been nice to have, but i can live without it since the 2 fill all the checkboxes above: - finger print reader for windows Hello My questions for those of you that own either one of the 2 products : - does the keyboard store illumination profiles? - are the profile used regardless of the controlling device? (so as when i switch to the other one, the lighting is kept) - does the wrist pad has a locking mechanism to the keyboard regardless of its type? - can someone check the Razer Naga Pro and tell me the FCC ID? it should be located on the bottom sticker - can both be customized in terms of backlight and shortcuts by the same software? - are there any issues with the support on MacOS? (BigSur 11.5.2 - worst case i presume it will be recognized as a generic keyboard and i can live with that) - can they use the same dongle? - not the end of the world, i can use the dongles on PC and BL on Mac
