We can’t imagine our Macs without cameras anymore. But as any tech customer support specialist will tell you, they also create the most common issues customers complain about. Although Mac camera not working is no doubt upsetting, it’s luckily quite easy to fix on your own in most cases.
Most Macs today come with a built-in front-facing camera, often referred to as the FaceTime camera. It’s located near the top edge of the screen and turns on when you open an app that is able to take pictures, record videos, or make video calls. Since FaceTime activates automatically, there’s no need to wonder how to connect camera on Mac. However, the activation process sometimes fails and it’s good to know what to do to get the connection back.
Get Setapp to fix your Mac problems
Whether it’s camera not working, Mac overheating, or you need to make a screenshot, there’s a fix for every problem inside Setapp.
When you have your MacBook camera not working properly, it’ll say disconnected or unavailable. The “There is no connected camera” error might surprise you anytime with any app if it finds your camera not working on MacBook. But don’t rush to assume that now you need to somehow “connect” the camera back on or that there’s a hardware issue that requires warranty service:
macOS doesn’t come with a camera settings app. Most apps that use the Mac camera come with their own configuration options, so there’s no on-and-off switch — neither physical nor software.
Even if you think it might be a hardware issue, you can usually resolve the problem of Mac camera not working quite quickly on your own with the help of a few little tricks
Below is a comprehensive guide to the tips you can use to get your camera back up and running should it misbehave.
We know that Mac camera is turned on automatically by the apps that use it. But what’s also important to note is that only a single app can utilize the camera at the same time. So when you have your Mac webcam not working, make sure you’re not being denied access to the camera because some other app is using it at the moment:
Launch Activity Monitor from Applications
Quit all other open apps or utilities that might be using the camera (e.g. Skype, FaceTime, and Photo Booth)
If you’re not sure which applications might be accessing your camera, save your work and close all the open apps to rule everything out
If quitting apps didn’t help, there might be a chance that some processes are using the camera in the background. A restart will almost certainly resolve the issue, giving you full access to the camera once again. To restart your Mac:
Select the Apple icon in the top menu bar
As effective as restart is, it takes time and halts everything you’re doing. Which might not be an option when you’re in the middle of an important FaceTime call. Fortunately, for FaceTime not working on Mac, there’s another trick that doesn’t require a reboot and fixes the problem immediately. That is using a command line to Force Quit the process:
Go to Applications ➙ Utilities ➙ Terminal
Click inside the terminal window and type sudo killall VDCAssistant
Hit Return on your keyboard and enter your admin password if prompted
Relaunch the app to see if the issue of webcam not working on Mac is resolved.
If you’re wondering why is my camera not working on my Mac when making Skype calls specifically, chances are that Skype is the app to blame here. Here’s what to do with your Skype camera not working on Mac:
Make sure that you have the latest version of Skype
If you do and there’s still no connected camera on MacBook — reinstall the app
Still experiencing the problem? Apply the same fix as described above for FaceTime not working on Mac. Then restart your computer and test Skype again.
Finally, check that you’re connected to the internet and your speed is sufficient enough (at least 128 kbps, or 1 mbps for HD FaceTime video calls). In case you do have problems with the internet connection, try WiFi Explorer, a network analyzer that helps identify and fix common network problems with your connection without involving a costly professional.
WiFi Explorer scans your network environment (band range, signal quality, security status), identifies channel conflict and coverage issues, and gives you quick recommendations to improve your WiFi.
Visual graphs in WiFi Explorer make it easy for you to assess the situation at a glance without diving deep into the numbers.
If you find the camera on Mac not working still and nothing of the above seems to help, you may try resetting what's known as the System Management Controller (SMC). The SMC manages a lot of hardware functions on your Mac and rebooting it may serve as a solution to your problems.
To reset the SMC on MacBook (2017 or earlier):
Shut down your computer
Plug in your power adapter
Hold down Shift + Control + Options keys and the power button at the same time
Allow 30 seconds to pass before releasing the keys, which will boot the Mac back up
Resetting the SMC on modern MacBook Air or Pro with the T2 security chip is different and involves a two-step process. Sometimes simply completing the first step will resolve the problem, but proceeding with both is generally a more solid approach for fixing the camera not working on MacBook issue.
The first step required to reset the SMC on MacBooks (of 2018 or later):
Shut down your Mac
Press and hold the power button for 10 seconds
Release the power button and wait a few more seconds
Turn the Mac on again
Check to see if you still have the Mac webcam not working problem. If the issue persists, proceed to the second part below.
The second step required to reset the SMC on MacBooks (2018 or later):
Shut down your Mac
After the computer is turned off, press and hold the right Shift key, and the left Option key, and the left Control key for seven seconds
While still holding the keys, press and hold the power button for seven more seconds
Release all and wait a few more seconds
Press the power button again to turn the Mac on
Assuming the problem with MacBook Pro camera not working was with the SMC, whatever the issue was it should now be resolved.
Reading through the what to do with the MacBook camera not working guide, you have to remember that your camera should work flawlessly most of the time. Unless your Mac tends to accumulate all kinds of useless files that might slow it down. No wonder then you might experience the Mac webcam not working.
Make your Mac work faster with CMM X
Download CleanMyMac X to optimize your Mac. Uninstall apps, get rid of clutter, and win extra space with a single tool.
Best advice here is to perform regular system cleanups — automatically. Use apps like CleanMyMac X to clean, protect, and optimize your machine’s performance to bring it to the state it once used to be.
CleanMyMac X optimization and maintenance tools sort through the old unused files, random app caches, and help you uninstall unnecessary apps completely without leaving behind the leftover bits on your drive. The app also scans for thousands of malware threats and neutralizes them in seconds, takes care of gigabytes of disk space taken by the email attachments you’ve never even downloaded, as well as removes histories, cookies, and caches from all the browsers you use. All in a single click.
If none of the proposed solutions can fix your Mac camera not working on MacBook, find an Apple Store or authorized Apple technician to have your Mac serviced. Or contact Apple’s telephone support. Remember that there also remains a possibility for mechanical or hardware problems with your camera, which are impossible to fix with software tweaks.
In all other cases, MacBook camera not working should no longer be a problem for you. Best of all, you can use both WiFi Explorer and CleanMyMac X mentioned above for free during a 7-day trial of Setapp, a platform of more than 150 apps that can fix just about any Mac problem in no time. Never miss your FaceTime call again!
Meantime, prepare for all the awesome things you can do with Setapp.Read on
Do-It-Yourself Video Repair Tool (VRT) – MP4视频文件修复工具 – MP4 Repair
|“We googled 2 days to find a solution to repair some broken .MP4 movie files – we couldn’t find one, so we|
started to build our own.”
Our repair utility can repair and fix broken or damaged video files (MOV, MP4, 3GP, M4V) that do not play in your media player. Please check in our practical use cases if your video file issue is a mission for VRT .
What exactly means REPAIR? Repair means that only video and audio portions can be repaired that are not lost: On some of your corrupt files, it MAY NOT repair anything at all, on some files it MAY repair some video portions, and on some other files it MAY repair both video and audio portions (It fully depends on the grade of corruption).
Currently, our software can automatically repair damaged .mov, .mp4, m4v, or .3gp movie files (generally, all movie files based on QuickTime container format) that use one of the following codec formats:
Movies of the following cameras have been tested for correctness with our software (however we cannot test all camera models, and it generally works on most digital cameras):
|Blackmagic URSA Mini 4.6K||For PCM audio, choose ‘Enable PCM detection’|
|Canon 60D, 5D, 7D, T1i, EOS 550D, Powershot SX20, S95||For PCM audio, choose ‘Enable PCM detection’|
|Canon 574HD||For PCM audio, choose ‘Enable PCM detection’|
|Contour HD Helmet|
|DJI Mavic Pro, DJI Phantom Pro, DJI Vision Plus 2||If video is stutters, choose ‘AVC1 single mode’ and ‘No CTTS repair’ under options.|
|Drift HD720||Experimental: Choose custom repair parameters ‘-single’ under options.|
|Flip Ultra HD|
|HTC EVO 4G|
|GoPro, POV.HD, Contour+2, ActionPro X7||If repaired video is hanging, try activating ‘No CTTS repair’ under options. If audio is missing, choose ‘Enable AAC detection’. If you recovered a GoPro/ActionPro video from an SD card media, your repaired video may freeze every few seconds. The reason is this camera stores additional files and your recovery software cannot filter out the additional files, and puts the data into the video files. Solution: use our data recovery tool (MaxDataGenius) to first extract the correct MOV files from your media.|
|iPhone, Nokia N82, Nexus One, all Android phones||If repaired video quality is bad, choose ‘No CTTS repair’ under options. If audio is missing, choose ‘Enable AAC detection’ under options.|
|Liquid Image HD320, Toshiba Camileo S30, B10, P100,|
AR Drone Quadcopter
|Experimental: Choose custom repair parameters ‘AVC1 single mode’ under options|
|Kodak ZX1, ZX3, ZI8, Z7590|
|Nikon Coolpix P300||Experimental: Choose custom repair parameters ‘AVC1 single mode’ under options|
|Olympus Tough TG-810||Choose custom repair parameters ‘AVC1 single mode’ and ‘No CTTS repair’ under options.|
|Panasonic HVX200, HXDC1, DC-GH5||If you have a corrupted .MDT file, use it for repair and rename it to .MP4 before running the repair. Choose ‘No CTTS repair’ under options if repaired video is hanging. If audio is bad, choose ‘Enable PCM detection’ under options. If video does not play at all, try option ‘Overwrite existing codec information by reference file’ . If importing of repaired videos does not work, reparied video must be converted after repair – reenconding/converting (using ffmpeg) for import is included in the program under options: If you choose ‘MP4 (same quality)’ it will use ffmpeg to convert the videos for import. Note: do NOT use Panasonic’s SD card file recovery (AVCCAM), the recovered MOV files are unrepairable. Solution: use our data recovery tool (MaxDataGenius) to first extract the correct MOV files from your media.|
|Samsung HMX200, HMXS10, MX20, SMX-F400BP/EDC and many other Samsung cameras||Experimental: Choose custom repair parameters ‘AVC1 single mode’ under options|
|SIV M7||Experimental: Choose custom repair parameters ‘AVC1 single mode’ under options|
|Sony XDCAM, EX1, F900,|
Other MPEG2 cameras
|If audio is white noise, under options, choose custom repair parameter ‘-af twos’ for PCM big endian, or ‘-af sowt’ for PCM little endian.|
If video is shaky, under options, choose:
1. Enable ‘reencode movie files’
2. Choose ‘Custom (ffmpeg) as ‘preset for reencoding’
3. Enter ‘mp4: -f mov -acodec copy -vcodec mpeg2video -sameq’ into ‘custom reencoder params’
|Sony DSC-HX1||Choose ‘Enable AVC1 single mode’, choose ‘Reencode repaired movie files (MP4 high quality)’, choose ‘Overwrite existing codec information by reference file’|
|Sony A6500, AX100, A7SII, A7RII, A7II||Choose ‘No CTTS repair’ under options. For PCM audio choose ‘Enable PCM detection’|
|XSplit Broadcaster||Experimental: Choose custom repair parameters ‘AVC1 single mode’ under options.|
|Yuneec Typhoon CG03||Disable ‘detect new movie clips’, enable ‘AVC1 single mode’, enable ‘No CTTS repair’|
|Zoom Q3HD||no audio|
|Your own camera and model…||Add your camera model with a simple click here…|
Additionally, if our software doesn’t support your camera yet, we can add support for new video and audio encodings (our 10 years of experience in data recovery software helps us to develop something new).
Mac: OS X 10.6 or higher (requires Intel-based Mac, PowerPC not supported!)
PC: Windows Vista / 7 / 8 / 10 or higher
Supported camera formats: See above
DEMO version restriction: The repaired files are only half the size of the repaired movie files in full-mode! (e.g. if the DEMO version repairs 50 MB, the full version will repair 100 MB)
NOTE: For a successfull repair, always study the camera specific options listed in above table!

Step 1: Add your camera model with a simple click here (we will update our software for your camera model as soon as possible)
Step 2: Verify that your camera model is supported by ‘reparing’ a non-broken sample file
If your camera model isn’t listed above, or the repair tool doesn’t seem to work with your movie, please first try the ‘repair’ using a non-broken (playable) sample movie of your camera to find out if the program fully supports your camera:
This approach ensures that there are not two issues at the same time (program does not support your model, and damaged files does not contain any data). If it properly supports your camera model, but doesn’t work on the damaged file, the damaged file is too broken for a repair.
After you sent us your sample movie, we’ll try adding support for your camera (this may take some weeks). All customer files are kept confidential.
Step 3: Your sample file repairs, but your broken movie doesn’t repair
If your sample movie correctly repairs (step 1), but your corrupt file doesn’t repair, we may check your corrupt file. Send us your corrupt movie (and one working sample movie of your camera) using an online file sharing service such as www.wetransfer.com (up to 2 GB files), www.wesendit.com (up to 5 GB files) or www.filemail.com (up to 30 GB files). After you sent us your truncated broken movie, we’ll examine it (this will take a few weeks). All customer files are kept confidential. Please only send small sample files (max. 100 MB), as we do not have a fast Internet connection here.
