Below, a touch sensitive button on the front of the webcam's face adjusts between 3 brightness levels for the ringlight feature for optimal lighting levels for your selfie stills or video capture. It's location may not be ideal though as touching the camera head to adjust brightness can all too easily bump it out of alignment.
Note these OSX 10.6+ compatible1080p HD autofocus webcams include a built-in microphones, H.264 video compression and a standard thread tripod camera mount hole in the clip base for those who'd prefer the stability and positioning control tripods can give you.
The UVC - USB Video Class device specification is firmly entrenched in the low-level software code of all major operating systems: Not just OSX, but Windows, Linix and Android OS as well. As such we expect that vast majority of more recent UVC compatible web cameras to work on the 10.15 version of Catalina MacOS without a hitch.
If there's any quirks about MacOS Catalina webcam compatibility, we'll note it on this website. As more app developers and end users deploy their webcams under the Beta and full release of Catalina we'll be sure to hear of particular cameras that exhibit any problems or issues.
There may be much older web cameras with outdated UVC device implementations that aren't up to snuff and may be problematic for use on MacOS Catalina, However most modern webcams should work on a Macs running Catalina just fine.
Depending on the model and street price, you can typically save $10 USD and often more by buying an inspected, tested and factory recertified and fully warranted refurb. Amazon tends to have a good refurbished selection of most of Logitech's current personal and group video conferencing cams on any given day. Click the link above to see their current selection.
For those into serious online voice and video conferencing, Skype, streaming, broadcasting, recording and more; the Marantz Turret Pro broadcast system is a unique Mac compatible peripheral that can consolidate much of your Apple computer AV setup into a single device. An autofocus 1080p driver-free UVC compliant web camera assures instant Mac OSX compatibility and is surrounded by a dimmable ring light. Snap-on filters are included for tweaking the ringlight's 3000K-7000K color temperature range to your liking.
On the audio front, the Marantz Turret broadcaster for Mac also incorporates a high-quality polar-pattern condenser microphone with pop filter. There are onboard controls to activate, mute, and control mic gain. A 1/8"/3.5mm amplified audio out jack for headphones assures realtime monitoring.
The webcam ring light microphone device houses a native Type-C USB-C connection, making it one of the few Mac webcams (like the 4K Logitech Brio) that offers the option of direct USB-C to USB-C connectivity for modern MacBooks, iMacs and Mac minis with Thunderbolt 3/USB-C ports. But it also works on older Mac's with conventional USB ports. There's also two conventional rectangular USB 3.0 Type-A ports integrated into the web camera's base to use as a hub for your other desktop gadgets.
Currently, the latest and best selling Apple compatible webcam for iMacs is Logitech's Logitech C922 Stream Pro. It's revised circuitry allows higher frame-rates than previous generations of their 9XX series webcams for exceptionally smooth video -- even when there's a lot of motion being captured. It's predecessor, the Logitech C920 is still a great external iMac webcam choice, especially at it's now lower street price.
For some, the best iMac compatible webcams to consider will have a standard tripod mounting hole built into the camera's base to allow the use of a floor, desktop or gooseneck tripod for optimal camera angles and positioning. Even if you just perch the external USB HD webcam atop an iMac's display bezel, you'll still have more control to tilt and pivot over the cam's position than you would with the built in iSight.
So, MacGizmoGuy figured that maybe the emerging voice and video conferencing scene on the Macintosh needed an ally and a Mac webcam reviews site to monitor the technology and help the use of VOIP, voice, video and teleconferencing slowly explode into the pervasive collaborative computing technology it is today. Thanks to all those who've visited or linked to this site as an online resource over all these years!
