Most Macs, with the exception of the Mac mini and Mac Pro, have a FaceTime camera built-in. Most of the time it, to coin a phrase, just works. Sometimes, however, it doesn't and it can be difficult to know what to do. So, in this article we'll show you how to fix it.

Mac mini: Display: 13.3in Retina display with True Tone: None (supports up to two 4K separate displays, or three is you buy the remaining Intel model). Camera: 720p FaceTime HD camera: n/a. Webcam Settings allows you to adjust settings including the exposure time, contrast, saturation, and white balance temperature for your webcam, whether it's a Built-in iSight, a more recent FaceTime/FaceTime HD Camera or an external USB webcam. Features. True hardware level control of your webcam. How Do I Activate the Camera On an External Monitor Via Mini DisplayPort? I have a 2015 MacBook Pro with a built-in Facetime HD Camera. I connect a larger Apple monitor via the Mini DisplayPort on my MacBook. Mac os x version 10 5 7. The monitor displys just fine, but I want to use the camera. Finding the best webcam for Mac and PC is a harder question to answer right now, during the widespread pandemic, than it ever has been before. The Logitech C920 Pro is the best all-around webcam because it has a 1080p camera, built-in microphone, auto-focus and lighting correction, and comes at a good price. The problem is that it sells out.
If your FaceTime camera fails to work, you'll usually see an error message on screen telling you that it has been disconnected or that it's unavailable. If it's unavailable, it may be that another application is using it. To find out, do the following.
In recent versions of macOS, you can control which apps have access to your camera. Go to Apple menu>System Preferences>Security & Privacy and choose Camera. You will see a list of apps that have access, to remove access from an app, uncheck the box next to the app.
If there is no app using the camera, or if quitting the app doesn't work, restart your Mac.
If quitting apps and restarting your Mac doesn't work, the next step is to recent your Mac's system management controller (SMC). It's not complicated, but it does vary according to the type of Mac you have and takes a little while to complete. Before doing that, I recommend optimizing your Mac and clearing out any junk files from apps that may be causing problems with your FaceTime camera. The easiest and quickest way to do that is to use CleanMyMac X. It tracks login items and launch agents, as well as hung applications and processes that are using lots of resources, any one of which could be causing a problem for your FaceTime camera.
Start at the bottom with Heavy Consumers, and click on each of the four categories. If you see a hung application or heavy consumer, press Quit to close it. Review the list of login items and launch agents. If there are any you don't need, check the box next to it and press Remove.
CleanMyMac X is notarized by Apple so it's safe to use on your Mac.
System Management Controller is in charge of keyboard, energy, lighting, and other basic functions of your Mac. When you suspect that the hardware may be involved, you may try to reset the SMC. It's basically a special Mac restart.
Once your Mac has re-booted, the camera should work as normal.
If your Mac camera is not working, there are several steps you can take to identify the problem and fix it. Use the advice above and it should be working in no time. In particular, using CleanMyMac X's Optimization module should help fix problems caused by other applications.
