EOS Utility macOS Update


Does anyone know when the EOS Utility will be updated for Mac OS 13? I'm opening it but it won't connect to my camera.

Thank you!

I’m using an EOS product… trying to connect my camera (I don’t think it really matters what camera, as long as it’s EOS) 

The same thing has happened with various Canon cameras. Please see my other reply in this thread for detail.



If you are using EOSU to download images from camera you can use Image Capture instead.

This was a major failure of Apple software engineering test and release procedures. (The last time I introduced such a serious bug into released software was 1985.) I use EOS Utility 3 to update date/time and IPTC info on my camera and I am unhappy about this loss of functionality.

After upgrade to macOS 13 Ventura, both Android File Transfer and EOS Utility 3 stopped working on my iMac. The USB ports were set to power only and no data during the update.

Someone at Apple support suggested that I reset NVRAM on my iMac and that restored data functionality of the USB ports. After that, Android File Transfer works and the Apple Image Capture App can talk to my EOS R5 over the USB C cable that came with the camera. EOS Utility 3 still does not work. This demonstrates that the USB firmware in the camera is fine, but EOS Utility 3 still has a problem. If resetting the NVRAM is necessary, that should have been noted by Apple software engineering and put into the release notes or better yet put into the software that did the update.

I have not yet tried deleting and reinstalling EOS Utility 3, so it is possible that might work.

Procedure to reset NVRAM:

Procedure to reset SMC on mac:

This is my best guess for the origin of the bug:

Accessory Security

New Features

  • On portable Mac computers with Apple silicon, new USB and Thunderbolt accessories require user approval before the accessory can communicate with macOS for connections wired directly to the USB-C port. This doesn’t apply to power adapters, standalone displays, or connections to an approved hub. Devices can still charge if you choose Don’t Allow.

    You can change the security configuration in System Settings > Security and Privacy > Security. The initial configuration is Ask for new accessories. Configuring an accessibility Switch Control sets the policy to always allow accessory use. Approved devices can connect to a locked Mac for up to three days.

    Accessories attached during software update from prior versions of macOS are allowed automatically. New accessories attached prior to rebooting the Mac might enumerate and function, but won’t be remembered until connected to an unlocked Mac and explicitly approved. (43338666)


While my iMac has an Intel CPU and not an Apple CPU, I speculate that Apple software engineering failed to perform adequate testing on machines with the Intel CPU before releasing the update.


Tried changing the security parameter (the camera was detected, as MacOS asked if I wanted to allow it to be connected), uninstalled ans reinstalled, but no luck.

Very annoying because I can't check and clean my memory cards on my normal computer being away.

After resetting NVRAM on my iMac, deleting EOS Utility3, downloading and installing EOS Utility 3 for macOS 11, now it works again. I hope this might be helpful for someone else.


John, (Cheers!)

Helpful.  I'm sure this will make some people's day here.

I also noted your reference about to the newly implemented thunderbolt security features requiring approval.  This was implemented in Windows eons ago.  I wonder if these permissions can be modified in Security Preferences without uninstall/reinstall of the EOS Utility?

If the entry is missing, users may also be able to browse to it, add then check to enable.

Hopefully one of the other users with this issue will test and report back. (I left my Mac is at the office)
