Please can you recommend the best Mac compatible webcam or third party compatible software I was told by Logitech the C930e is the best as the software is the most Mac compatible .. However .. I do not like the addition of the ultra wide angle .. I was told by Logitech the C922 Pro software is only partially Mac compatible and so there is no way to manually focus and that is important to me .. And the C920 software is not Mac compatible at all .. I am open to other brands and have yet to look at the Microsoft LifeCam .. I have heard there are Mac compatible software alternatives but do not know anything about them .. I am studying american crows .. I will use the webcam to spy on a bird platform that is 30ft from where the webcam will be and thus the need for manual focus and the need for not too wide of an angle .. I will then need to run a 32ft active USB cable to my iMac .. Thank you all in advance ..
