In years past, they had a very spotty history of commiting to support Apple web camera compatibility whole-heartedly, but they've gotten somewhat better as Apple's market-share and dominance has increased. Then again, without a 4K sensor, their time is running out anyway.Logitech Webcam Software For Mac The largest manufacturer of - and arguably the best webcams made - are from Logitech. It’s too bad too, in certain circumstances, they were really nice cameras when they worked. I imagine if anyone outside of Logitech knows if there’s anything goofy with the UVC implementation on those cameras, it would be the folks who maintain the UVC (or, what’s it called, “video for Linux” I think) software on Linux. And I bet the Linux devs got it working with no help from Logitech. But I went back to try it about a year ago to see if I could use one as a security camera with a Raspberry Pi, and it worked with full hardware acceleration. I recall being upset at the time because my 920s didn’t work right on MacOS or Linux, and I didn’t want to build Windows boxes just to get the hardware encoder to work, which would then not use any CPU. The only other thing I can suggest is you find a support community for webcams on Linux. Of course I’m speculating entirely, which is all any of us can do unless Logitech actually releases information, which I assume they won’t. So I have a feeling, because of that weirdness, there’s something odd about the UVC interface in those cameras and Apple has finally removed the hack that kept it working, or they removed some compatibility with an old revision of UVC that it relied on. God, I wish I could work at a company like Logitech and get paid to be that stupid. Their stated reason for doing so is that it would interfere with the normal usability of built-in Mac apps like Photo Booth. Unfortunately, Logitech refused to provide a driver for the camera, opting instead to give the camera a UVC-compatible mode that bypasses the hardware encoder, for Mac users. I was excited at the prospect of being able to do 1080p video without my then-2008 MacBook Pro’s fans going full blast because it had to encode HD video on the CPU.

I had a couple of 920s when they first came out. The 910 and 920 were some of the first webcams with built-in h.264 (MP4) encoders and as such they were never truly 100% MacOS compatible. Knowing Logitech they’ll just come out and say the 910 is not compatible and discontinue it, if they haven’t already.
