Mac camera light blinking and flashing green

I had this same exact problem about 4 months ago in and it resolved itself about 5 weeks later. I didn't do anything special besides stopping use of my computer for video calls/Zoom, and it somehow mended itself. However, yesterday the same camera issue came back, and I don't really have 5 weeks to just let it heal itself on it's own since I need the camera for school now. I'm hoping there's a software fix coming along soon, or that a concrete answer is in the works because this is a little ridiculous now. I sort of have a feeling it has something to do with Zoom, but since that isn't going away, I need Apple to make this work! I've tried resetting the SMC, running diagnostics--no issues found, I've tried using Terminal to fix the camera assistant whatever, I've tried gently vacuuming the hinge and vents...HELP!!

Yes! I bought another camera but It doesn’t feel great knowing my new MacBook Pro is a defect very expensive piece of equipment. Is this my last Mac?

if a camera on a laptop doesn’t work, what will also not work in a while?

it shouldn’t be so hard for Apple to fix this. My problem isn’t hardware related.

So THIS is weird, I tried the vacuuming and it WORKED!

Today, my camera has started working again. I was so surprised, that I rebooted my MacBook Pro (late 2016) several times and started using all my installed apps (Facetime, Photo Booth, Zoom, Teams etc.). Still all good. What had I done? I had carefully vacuumed the hinge with a vacuum cleaner. Et voilà. Maybe that works for you, too.

I have the same issue. Green light turns on and there is a black window and after few seconds the green light goes off and in 2/3 secs I get a message. - no video, FaceTime has not received any video from the connected camera. Restarting your computer may fix this issue.

This is the same problem for Facetime, photobooth, skype, zoom, teams

In hardware I see built in Facetime camera and its details.

I have done all the recommended steps as mentioned - https://support.apple.com/en-us/HT211130

I would run a Mac Diagnostic, there are some reference codes specific to the camera.

I am having the same exact experience. My camera light turns green but doesn't turn on on any platform. It started about a month before school ended... in May, probably. Being a school teacher and need to video chat with students, it became a big problem. I had to video chat on my phone and use my computer to share lessons. School is starting in 2 weeks and the issue isn't solved. I Uninstaller back to factory settings and everything wiped out but didn't reinstall for 2 days and 4 different Apple online appointments. Frustrating, imagine online teaching with no computer and COVID and NO stores to buy a new laptop!!!. I got it back to where it was... i have my computer but no camera in photobooth, zoom, teams... nothing. I have the lightning Mac. I use it strictly for school and is less than 3 years old. Uggg.

Mine is a one year old MacBook Air and my problem differs a little. Camera just stopped working in June. First troubleshoot w/ Apple Chat showed that computer still recognized the camera, which they said was a good indication. But after all their suggested resets, camera no longer is listed. Final try was upgrading to Catalina. Camera is gone!

After completing the steps listed here, did you also run a Mac Diagnostic? There are some reference codes specific to the camera.

Have you run any "cleaning", "optimizing", "speed-up" or anti-virus apps on your Mac?

Class action???
