Now that everyone carries their camera with them everywhere, we can all make a claim to the title of “photographer.” And as image enthusiasts, blurry photos are annoying. They’re also extremely common, considering how frequently folks try to talk pictures in environments that don’t help your camera’s autofocus. Back lit environments, dark interior rooms, spotlit. Recently ordered a 7390 2-in-1. I believe it's the latest refresh since it's running an i7 1065g7 cpu. Long story short, the webcam image is very blurry and pixelated and I'm hoping to find a fix. Laptop review videos seem to show much better quality imaging than what I have: much less, if no blur. It is blurry for all apps. It is blurry with my MacBook Pro lid open or closed. It is blurry before and after plugging in my Thunderbolt cable. The screen and camera lens are clean. The built-in camera on my MacBook Pro, connected to this Thunderbolt Display, is crystal clear. I have the latest display firmware, 1.2, and the latest MacBook Pro.

Even the front-facing camera on Apple's new iPad Pro- announced Wednesday alongside the new MacBook Air - offers 7 megapixels and shoots 1080p video at 60 frames per second.
The image on the screen is blurry. I reset the SMC and PRAM, tried a SafeBoot (which by the way causes a No Camera Available message to appear in FaceTime.
The Camera worked great last week, now suddenly the blur.
How can I determine if it is hardware or software?
Any ideas?
Verify there is no smudge across the camera eye at the top of the screen— clean with a soft cloth.
To trouble shoot further you can:
Try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot and test as caches get rebuilt.
This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.

After connecting my newly-purchased Mac mini 2018 to my Dell U2410 24 inch 1920×1200 LCD monitor by HDMI cable, I notice that the text is a little blurry and pixelated. The lines aren’t smooth, but jagged. The text looks like it would on an old analog TV.
The problem is caused by the Mac choosing to talk to the Dell monitor using YPbPr, an input color format previously used by S-Video and composite video for analog TVs. The Dell monitor supports two input color formats, RGB (digital computer standard) and YPbPr (analog TV standard). I am not sure why the Mac defaulted to using YPbPr, instead of the superior RGB color format.
Note: I did not see this problem when connecting my MacBook Air 2015 to the Dell monitor using the Apple Mini DisplayPort to DVI adapter. Online comments seem to indicate that this issue only occurs with the 2018 (and probably later) Macs.
The solution is to force the Mac to use the RGB input color format for my Dell U2410 monitor. This is accomplished by creating or overwriting the macOS’s EDID (Extended Display Identification Data) configuration file for the Dell monitor. The details are documented by this webpage, Fixing the External Monitor Color Problem with My 2018 MacBook Pro.
Tip: To verify that YPbPr is being used by your monitor, check the “Input Color Format” in the monitor settings. On my Dell monitor, I go to the monitor’s settings Menu and select “Color Settings” to view the “Input Color Format” field.
Macbook Camera App
Because the EDID override files are located in a protected system directory, “/System/Library/Displays/Contents/Resources/Overrides/”, we will need to use the macOS Recovery Mode to write to it.
Here are the steps I took:
![Macbook Pro Camera Blurry Macbook Pro Camera Blurry](https://i1.wp.com/techpatio.com/wp-content/uploads/MacBook_Pro_glossy_screen_reflection-300x225.jpg?resize=300%2C225)
- Download the “patch-edid.rb” script file from GitHub’s adaugherity/patch-edid.rb project. This script will create an override EDID file to force RGB usage. Look for the “Download ZIP” button near the top-right. The archive file will be downloaded to “~/Downloads/7435890-00ff3ead17ae77d2f1c376e90831c037b7dea7ed.zip”.
- Unzip the downloaded archive file by double-clicking on it. (My Safari browser automatically unzipped the archive file after downloading.)
- Launch the Terminal app and run these commands:# Rename the unzipped folder to a nicer name, 'patch-edid'
mv ~/Downloads/7435890-00ff3ead17ae77d2f1c376e90831c037b7dea7ed ~/Downloads/patch-edid
# Change directory to the 'patch-edid' folder
cd ~/Downloads/patch-edid
# Ruby should be pre-installed; double-check by getting version info
ruby -v
# Execute the script
ruby patch-edid.rb- The script outputted the following on my Mac:Found display 'DELL U2410': vendor ID=4268(0x10ac), product ID=61462(0xf016)
Raw EDID data:
00ffffffffffff0010ac16f04c5055310914010380342078ea1ec5ae4f34b1260e ..
Setting color support to RGB 4:4:4 only
Number of extension blocks: 1
removing extension block
Recalculated checksum: 0x38
new EDID:
00FFFFFFFFFFFF0010AC16F04C5055310914010380342078E21EC5AE4F34B1260E ..
Output file: /Users/chanh/Downloads/patch-edid/DisplayVendorID-10ac/DisplayProductID-f016 - Take note of the output file, “/DisplayVendorID-10ac/DisplayProductID-f016”. We will need to put the ProductID file with its VendorID parent folder under the EDID overrides folder like so: “/System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-10ac/DisplayProductID-f016”.
- On my Mac, the “DisplayProductID-f016” file did not exist in the system “Overrides” folder. However, the “DisplayVendorID-10ac” folder did already exist there.
- The script outputted the following on my Mac:
- Reboot into the macOS Recovery Mode. When the Mac starts up, hold down “Command-R” (hold down both the “Command ⌘” and “R” keys) and release when you see the Apple logo.
- Tip: An easier alternative is to hold the “Option/Alt” key on boot to launch the Startup Manager. Then just click and release “Command-R” keys to launch into the recovery mode.
- Once in recovery mode (you will see “macOS Utilities” in the top menu bar), click on the “Utilities” menu and select “Terminal” to launch the Terminal application.
- On my Mac, the main “Macintosh HD” drive is automatically mounted. If it isn’t on your system, launch the “Disk Utility” first (before the “Terminal”), select the “Macintosh HD” disk (or whatever you named it), and click the “Mount” button. Quit the “Disk Utility” when done in order to launch the Terminal application.
- Run these commands in the Terminal:# Change directory to your 'patch-edid' directory
# Note: Change the 'username' string below to your actual username
cd/Volumes/Macintosh HD/Users/username/Downloads/patch-edid/
# Copy your override subfolder+file into the EDID overrides system directory
# Note: Change the 'DisplayVendorID-XXXX' to your actual DisplayVendorID
# Do not include ending forward-slash at end of 'DisplayVendorID-XXXX'
cp-R DisplayVendorID-XXXX /Volumes/Macintosh HD/System/Library/Displays/Contents/Resources/Overrides/ - Quit the “macOS Utilities” to reboot.
Macbook Pro Camera Is Blurry
After reboot, the text on the Dell monitor is no longer blurry and pixelated. The text looks sharper and the lines are smoother. (Unfortunately, the photo to the right does not show the blurry/pixelated text very well.) When I check the monitor’s “Input Color Format”, it now says “RGB”. Success.
