Hello, Please I just realized that my macbook camera isn't working for my applications (Photobooth and Facetime) after I updated to macOS Catalina.


Kindly help me resolve this error.

I just had this error after upgrading to 10.15.7


After some stress, I fixed it by:


1) opening Screen Time in System Preferences, then adding my browsers, FaceTime, Zoom, etc, to the section "Always Allowed"


2) restarting


3) tested things starting with FaceTime (I figure Apple is going to be the most relaxed about their own software).


The camera and microphone worked as normal in all the apps. I also noticed whereas before in Security & Privacy, the Camera and Microphone sections didn't allow me to add anything, those areas were now behaving as one would expect.

Inform Apple of this.

Either they didn’t fix this, or it’s a Third-Party App getting in the way. Read the post I provided above: https://discussions.apple.com/thread/251194697?answerId=253020269022#253020269022

"No Camera Available Error on macOS Catalina: I have this issue too and none of these fixed it. Any other suggestions?"

Seems to be a glitch in the macOS.


Takes a Few Steps:

Without getting too deep into it, the only way I've been able to solve this is through the use of SIP Management, User Creation, Terminal Commands, and a Third-Party App designed for Disabling and Enabling the iSight Camera. I'll leave it at that. ;)


Figured this out today, my time.


So, Report this to Apple:

Apple won't get back to you directly, but the more they hear of this, the more they'll know what to fix. So, provide your feedback.

  1. Go Here: Feedback - macOS - Apple
  2. Select: "Bug Report" for the "Feature Type"
  3. Select: "Applications/Utilities" for the "Feedback Area"
  4. Proceed from there as Necessary

Hi, I am getting the same error since yesterday. 2 days ago the camera worked fine, the day after it stopped working showing this error text (after 3/4 seconds of green light on, the one beside the camera):

"FaceTime has not received any video from the connected camera. Restarting your computer may fix this issue."



Could you please let me know in you had the same error message? I noticed there are many users experiencing the same issue, and at this point I really think it is a software issue rather then an hardware one.


I called Apple support and after various attempt they said it is an hardware malfunction. Now I should pay, I do not know how much, for something that it is a software bug. :(


Thank you

I have exact same problem. Stopped working after unfortunately I missed the auto update and it proceeded overnight. I do not allow auto updates normally b/c each time there is a new OS my computer has big problems. I have found best to wait for many bugs to be worked out. Camera was working before now after auto Catalina update not working, not rocket science. This laptop is a big dud w/ keyboard, screen, keys falling off (all Apple admissions of product problems) :/ tough b/c my last Mac Pro also had hard drive crash after a few years...what is going on? I used to think so differently of Macs and their overall integrity. Not happy esp right in the middle of stay home orders where video is fundamental and has caused me to not be able to WORK!!

I have the same issue with my the camera in my Thunderbolt Display, no matter whether I connect the Mac mini (2018), my 2017 MBP or the previous Macbooks, appearing since one of the last upgrades. I tried all suggestions that I could find on the net.


Salient detail: the camera works perfectly when I boot into Bootcamp Windows 10. So, that excludes any hardware issues that are suggested: same hardware with a different OS works fine.

Yes, it's pretty annoying to say the least.

Especially considering the fact that I moved to Apple products about 18 years ago mainly because of the seamless integration between the OS and hardware and stayed with them mainly for the way all the other devices work together. (Macs, Macbooks, phones, tablets and watches, iCloud).

But nowadays, the only solution that I have found to work for me to be able to work from home office (apart from using my phone) is running Windows as my primary OS to make my pieces of Apple hardware work together. It's really a shame!

No, it does (did) not.

That's why I thought that probably the camera itself was broken. That's why I tried several MacBooks and they had the same problem with the built in Thunderbolt camera. But then I found out that it worked well in Bootcamp Windows, both the camera function and the LED, so I concluded it must be a driver/OS problem.


The LED did light up every time I booted into Catalina but extinguished again within a fraction of a second. No camera was listed in the system overview. So, it behaved like some driver crashing every time.


But, suddenly, this morning (European timezone) when I switched on my Mac again I decided to have another look in system overview first. The camera was listed and remained on the list, so I tried a few apps and the camera seems alive and kicking again. There were no upgrades in between, I did not change anything myself, just booted up normally like every morning and suddenly it's there.


Strange, but it seems to work for now, and continuous to do so even after several reboots.

Just visited the Genius Bar. They ran a bunch of diagnostics. Took it to the back and made sure the cables were well connected. Nothing worked. The gentleman was very helpful but his only solution was to replace the entire screen which would cost me $650CAD.


This is extremely frustrating because I haven’t done anything to my Mac beyond just updating the OS and now they only way to fix the camera and light sensor is to spend a bunch of money.


Feeling helpless.....
