Macbook Pro camera doesn't work. "No Video".

Hello, Laurii112.

Sorry to know you're having this problem with your MacBook Pro.

If you haven't rebooted into safe mode anytime recently you should try that to see if it helps. Let the Mac OS do drive directory repair, cache clearing and other misc housekeeping. Often just booting into safe mode and logging in, then immediately rebooting normally will resolve an issue.  You should do this with all your external peripherals disconnected but the keyboard and mouse.

Booting into Safe Mode… 

Use safe mode to isolate issues - Apple Support

What Safe mode does:

• Verifies your startup disk and attempts to repair directory issues, if needed
• Loads only required kernel extensions
• Prevents startup items and login items from opening automatically
• Disables user-installed fonts 
• Deletes font caches, kernel cache, and other system cache files

Restarting in Safe mode can often eliminate a problem or help identify the cause.

You can verify that you have started in Safe mode by clicking the Apple () menu > About This Mac > System Report. Then find >Software< in the left column and look at >Boot Mode: Safe vs Normal< in the right pane.

Note– starting up in Safe mode could take 10 minutes or more. Be patient.

Does the problem persist while in Safe mode? 

Restart your Macintosh and re-evaluate the issue.

What you said is required in Catalina to have permissions, just it. It is not the same problem that we are reporting!

A lot of people having the same problem.

• Zoom, QuickTime and Photo Booth neither are working.

• I started thinking it could be related by a firmware problem. That's because my Camera is not being recognized.

You problem with the cameras is different from the one related to post, even if I think are more or less linked ins somehow.

This is the error message many people are getting as well:

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

The Camera of my Macbook Pro is not working. When I start the Facetime for example it shows a black screen for about 30 seconds and then displays this message:

The camera seems to be correctly installed

The camera also does not work with any other apps. When I start these apps, the green light does come on, but turns off after about 30 seconds and the camera never works.

I have tried the following methods to fix the issue, but none have worked:

1. Installed OS software update (10.15.4)
2. Made sure all appropriate apps have access to the camera in preferences > privacy > camera
3. Given all of these apps permission to control the computer in preferences > accessibility
4. Rebooted in Safe Mode
5. sudo killall VDCAssistant and sudo killall AppleCameraAssistant in terminal
6. Logged into the other user account on the computer, and the problem persists.
7. Checked to see that System Report recognizes the camera

I have been told to bring the laptop in assistance because it could be an hardware issue, but I am not really convinced of this. Too many users are having the same issue at the same time.

Is Apple aware of this issue? Are they working on it?

I have raised Aldo a bur report here https://www.apple.com/feedback/

In the current time, it is really frustrating having a laptop without the camera and I am wondering if and when this will be resolved.

689 people marked "I have this same problem." Apple ships over half a million of these notebooks over the course of the year.

I would not say that's a majority, even though not everyone who has the problem is aware of this thread. Even so, the more who report it to AppleCare, the more that increases the chance of Apple finding a solution for it.

I have upgraded to 10.15.5 but the problem still persists — no app connects to the camera! Camera light goes on for a few seconds but does not connect to app (zoom, skype, Facetime, etc).

Was on phone with apple support for two days and tried all possible options including reinstalling OS but nothing worked! Frustrating to says the least ...

Make an appointment at your nearest Apple Genius Bar (if they are open) for a free diagnostic check.

In the meantime download and run Etrecheck. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support  to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.

Dears

I have the same problem.. due to the current situation, we are confined and I need urgently the camera to work.. It has not worked for some time and I need it for my classes.

I cannot go to any shop.

My camera shows a green light when activated but is black.

What can I do [URGENT]

I tried rebooting in safe mode… FaceTime shows [No camera available]

@Laurii112

First let me share my MBP specs:

16" (Purchased in Late Feb/Early March 2020)

2.3GHz 8-Core Intel Core i9

64GB DDR4 RAM

1TB SSD

AMD Radeon Pro 5500M 4 GB/Intel UHD Graphics 630 1536 MB

The fluff:

I have a beast of a machine based on my previous 2015 Macbook Pro. I upgraded because I needed to and because of the current global climate, I have had to become a livestreamer. I have used various different program combos to achieve the goal of staying connected. I use a combination of the built-in FaceTime camera and an external Logitech HD 1080p webcam.

The meat:

Ok, so this issue popped up for me after an OS update from 10.15.3 to .4. It seems there was some issue in how the graphics drivers were packaged. I had all my peripherals attached which included, 2 USB-C hubs, Thunderbolt3 to HDMI, & USB-C to USB3.0 adapter with an iLok dongle. After disconnecting all the peripherals and then "docking" the Macbook back sometime later (roughly 5 hours), the built-in display FREAKED OUT after I plugged the Thunderbolt3 to HDMI cable back in. This caused a kernel panic and prompted a restart. After that restart, it went into Safe Mode. I rebooted into Normal. Reconnected the Thunderbolt3 to HDMI adapter which seemed to work and went through to make sure everything else was fine. So, I brought up my web conferencing app and lo and behold...

...No pretty green light. No FaceTime camera access. No external USB camera either. This happened 2 hours before I was going live. Nothing worked. So I did what I could and touted "technical difficulties" as one should to maintain an air of professionalism, waited until the stream ended and went to bed after 3 hours of frustrated troubleshooting and a glass of whiskey. The next day I initiated an Apple support chat along with 4 hours of continued troubleshooting on my end. SMC & NVRAM/PRAM resets did nothing. The process for the current line of 16" MBP's is not user friendly. Not easy to accomplish unless you are a freaking clock. 

I also tried the sudo killall VDCAssistant about 10 times and it didn't work. Atleast when I pulled up Activity Monitor, it did show that process only after I selected "All Processes" from the "View" menu. I tried killing the process that way too, then retried my cameras which still didn't display anything. Also note, the issue was not that macOS couldn't find or locate the cameras because they were all selectable from every program I used. Just no video output or any other indication they were working properly. 

Here's what worked for me: 

(I had a TimeMachine Backup right after the OS update. If you have that, you might be able to continue on. Even if you don't try this process. It's going to take time no matter what. It is a better alternative than sending it in to get serviced.)

1.   Reboot/Restart from Apple menu.

2.   Run Diagnostics. (Press "D" on your keyboard immediately upon starting up.) Allow the program to run. Mine told me there were no hardware issues. Not surprised. 

3.   Wild goose chase trying to reinstall macOS Catalina from my Time Machine Backup which failed twice. Rebooted. Tried again.

4.   Went into macOS Recovery Mode: Command (⌘)-R. I deleted the ENTIRE Macintosh HD drive structure. (Macintosh HD - Data needs to go bye-bye as I believe it contains the culrpit or some software/hardware handshake has failed)

5.   Reinstalled a fresh macOS Catalina 10.15.4 (won't allow downgrade to .3) 

6.   Once that was finished, I tried both my cameras. They each worked once and only once. This essentially showed me there was something wonky in the way macOS handles a driver. (Mac experts please correct me if I'm wrong)

7.   I then decided to use Migration Assistant to install my last saved and known good backup from Time Machine Backup. This process took roughly 3 hours from start to finish. 

8.   Went into Disk Utility to run "First Aid" on the drive. No errors were reported. 

9.   I rebooted once it was done to help settle things into place. 

10.           I logged back into the OS and tried everything again and both FaceTime and my Logitech HD c920 camera were both working again. 

11.           Crossed my fingers, held my tongue just right, said a little prayer, shut down all applications and tried them again. 

12.           Both cameras still worked. Albeit, the built-in FaceTime camera seems a little more "grainy" than it originally did. 

As of right now (3/28) everything is still working. I'll be happy to respond to any questions you may have as I believe my experience is going to be anecdotal at best. 

In the problem user download and run Etrecheck.

I, too, was having problems with my camera recently after it worked for me for the last 9 years. I tried all the things mentioned above and then I tried a mixing a few of the information. I went to Settings, then Privacy, clicked on the unlock button, then clicked on Accessibility and then at the bottom of the right hand column that says Let the Apps Below To Control Your Computer, there is a plus (+) sign. I clicked that, which opens the Applications file. Then I just clicked on Facebook, WebEx Teams, and Zoom. Clicked on the lock on the bottom lefthand corner and restarted the computer. And that worked for me.

Good luck to the rest of you, as I can completely sympathize with what you're going through.
