I recently purchased a Logitech C920 Pro Webcam (it isn’t nearly as big as it looks in the pic) to use with my new MacMini. Research showed that it is supposed to be compatible with macOS 10.10 or later. Well it is compatible, but it sure isn’t easy to get it fully functional on macOS 10.14 Mojave!
Jump to “The Solution” if you don’t want to read the details.
The C920 is plug and play (up to a point). Plug it into a USB port and then fire up FactTime or open QuickTime and start a movie recording (File/New movie recording) and either program will use the cam.
It is always necessary on Mojave to authorize access when using a program that wants to access the camera or microphone. So the first time that you fire these up you will get this prompt from macOS:
Click OK and now QuickTime will have access to the cam and be able to record from it. I did the same with another program called ScreenFlow and it worked the same after granting access and was able to record from the cam. Great! But I felt like it needed some tweaks to the camera settings.
Google said that I needed to install “Logitech Camera Settings” from the Mac App store. No problem, it’s free! I download it, open it, and not much happens.
It sees the camera as it is listed there at the top of the window, but everything is grayed out. None of the controls on any tab will do anything. I suspect that it isn’t nicely “asking” if it can use the camera and so you never get the prompt to give it access. Since there is no access there are no controls available.
With a little more Google I find that this is a common problem on later versions of macOS, but no clear cut solutions. Some suggested installing “Logitech Gaming Software” so I head to the support page listed on the “Setup guide”:
I find “Logitech Gaming Software” on the downloads page (the only thing there) and download and install it. It doesn’t say anything about a webcam and doesn’t offer any help. “Logitech Camera Settings” crashes if I try to run it while “Gaming Software” is running. I un-install both of those.
More Goggle and I finally find the answer! The Logitech C930e download page has a newer “Camera Settings” program that lists support for macOS 10.14 and some say they have used it with the C920. So I download and install that and Varooooom! It works when I fire it up and authorize access to the camera! Logitech, why don’t you link that program on the C920 download page as well!?
The Advanced tab has controls to tune the camera just the way that you need it. I covered the lens as I don’t have a green screen yet and it is kind of messy behind me, but the video really is there.
I still haven’t figured out how to make settings “stick”. I have to run Camera Settings each time and keep it open while I use another program such as ScreenFlow to make a recording. Once I close Camera Settings down the cam reverts to the default settings.
I hope this is a help to someone.
