EOS Webcam Utility not working under Mac OS Sonoma 14.5?

Stefan1 — Tue, 28 May 2024 12:31:01 GMT

Dear community,

My Mac upgraded to "Mac OS Sonoma 14.5". "EOS Utility 3.app" seems to connect fine, and the "Remote Shooting" / "live view shoot" feature seems to work just fine. But the rest doesn't: "EOS Webcam Utility Pro", Zoom, Teams etc. don't seem to connect and only show the "EOS Webcam Utility" home screen, instead of the usual camera stream.

So basically I can no more use the camera as a high-end webcam for which I am using the camera to record videos as I speak at online conferences.

Any ideas what is happening? Is this indeed linked to the Mac OS Sonoma 14.5 upgrade? Any ideas for troubleshooting?

Does this help?

thanks for your feedback. I had the the Pro software already installed and it was updated. So that didn't make a difference. I don't need that software either; the key is that Zoom and Teams etc. work. But they don't...

I cannot even get EOS Utility to connect to my R-5. It doesn't see the camera. My workaround is to use Apple's Image Capture to transfer photos from the camera to my Mac, and then the Rename function of Canon Digital Photo Pro 4 to rename the files. Basically I have had to break the EOS Utility function into two other apps. It's cumbersome, but it works.

I don't have trouble transferring the images (you might as well simply use the SD card for that); my primary use case is to use my R6 as a webcam for online-conferences and video-taking.

To use my R6 as a webcam, I have to rely on EOS Utility – I don't know any other way. And EOS Utility doesn't seem to work anymore. I am assuming it doesn't work anymore since my Mac upgraded to "Mac OS Sonoma 14.5", but even here I am not sure.

Any ideas how I could identify the error with certainty?

Any other ideas?

Any alternatives to EOS Utility?

I have purchased elgato camlink 4k. This worked immediately.

The Canon EOS Utility is not reliable, and I hope the elgato camlink 4k device will take over from there.

Having said that, it is quite deceiving what Canon offers. The entire Canon software feels like from the medieval ages...

Leveraging elgato camlink 4k works, but now the problem is that the camera keeps going to sleep after 30min while I am live streaming. Any way of resolving that?

Why is Canon giving us all that pain?

Here is how to overcome that problem:

The EOS R6 is able to continue HDMI output passed the 30 minute cut off. To do that the camera will need to be in either P, Tv, Av, or M movie mode. Then press the Menu button, go to the eighth page under the red camera tab, select HDMI Display, and set it to the option that has camera and computer screen icons. Once you've done that go to the third page under the yellow wrench icon, select Power Saving, and double check that Auto Power Off is disabled.

Once both of those are set the camera will be able to continue the HDMI output beyond the 30 minute cut off. If you would like to reference the manual for information on that it is noted on page 353. If you need a copy of the current manual it is available HERE. Once you are on the web page click on the Manuals tab and the one to reference is named EOS R6 Advanced User Guide.

After much frustration, and uninstalls/reinstalls, I stumbled upon an answer. I noticed that my camera (80D) would communicate correctly with EOS utility, but would not work with webcam utility. As I was puzzled, staring at the camera in disbelief, I noticed the red disk activity light was practically on solid as webcam utility was (trying to communicate?) open. So, I decided to remove the memory card, and wouldn’t you know, the camera immediately became available in webcam utility. Why? Maybe macOS sees that card as something other than the camera? Who knows. But this simple step solved my weeks long headache…

Just sayin’

I can't believe support at Canon is not responding to this. IOGEAR doesn't know what is going on, Apple tells me to update the Canon driver. But Canon is silent. Really crummy support here.

I was able to get it working on Sonoma 14.6.1 for a brief moment - like about 10 minutes.

I then updated EOS Utility to 3.18.5.13. But then the EOS Webcam Utility stopped working.

Have tried various things over the past hour but have not been able to make it work again.

A clue I could find was in Console by search for "eos". Unclear what it reveals but *may* suggest that there are possible exceptions halting proper function. Does anybody else see anything similar?

default 22:10:21.618388+1000 com.canon.cusa.eoswebcam.cameraExtension UNIX error exception: 3

default 22:10:22.624265+1000 EOSWebcamService CMIO_DAL_System.cpp:85:Get System unsuspended

"4cc_pids_glob_0000" = "";

}

The UNIX error exception: 3 reveals

com.canon.cusa.eoswebcam.cameraExtension (Security)

Subsystem: com.apple.securityd Category: security_exception

CMIO is related to Core Media IO

Now considering how I do a proper clean uninstall of both WebCam and EOS Utility to see if I can start from a clean state.

I had this problem in May 2024 when Sonoma came on and I fixed it thanks to this blog post https://appleinsider.com/articles/23/10/25/what-to-do-if-your-webcam-doesnt-work-in-macos-sonoma
I did it and it worked again.

Now in Aug 2024 my webcam stopped working again.
I have an 80D, with the latest firmware 1.0.3
I use it on a Macbook PRO M2 Sonoma
I have the latest version of the EOS Utility software updated here.

I use this camera with a USB cable (not HDMI) and it worked beautifully on Zoom, Streamyard etc.

Now in Aug2024 out of nowhere what is happening is:
- the camera is rightfully recognised when I open EOS Utility.
- I quit it so it doesn't clash with the other app such as Zoom etc
- when I open Zoom etc it gives me now permanently this screen (which is different from the screen I used to have in may 2024 or whenever it wouldn't recognise the camera due to a bad cable or such, which is this screen with a red x on a cable, meaning I didn't find a camera connected to the mac). So it's worse because now even if the cable isn't even connected, the screen remains the same, and the video just doesn't load or start

PLEASE HELP

Solution to Canon EOS Webcam Utility not displaying the screen or working! It keeps displaying:

Canon latest web cam driver abnormal solution

The process is as follows:
1. Uninstall C 1.3.16. Uninstalling is difficult, please try various methods.

EOS Webcam Utility 1.3.16 [Windows]
Last updated: 08-Jun-2024
Release number: DLAP000408

2. If Eos Utility is installed, disable auto-start.

EOS Utility 3.18.40 for WindowsLast
updated: 10-Sep-2024Release
number: 0200721105

3. Find and download the old version of EOS Webcam Utility, which is version 1.1 (the latest version on the official website is: EOSWebcamUtility-WIN1.3.16.zip)

Old version download link: https://downloads.canon.com/webcam/EOSWebcamUtility-WIN1.1.zip

4. With the camera cable plugged in and the camera not turned off, install the software (a confirmation window for installing the video driver will pop up) and restart.

You can use the Canon live broadcast software normally, and there will be no missing picture!

Personally tested!!!

This is the case for both win11 and win10 systems, so the fundamental problem that Canon's live broadcast software cannot be used is Canon's software driver problem, which is caused by the failure to adapt to win10 and 11 or some updates to the win system.
