I use the EOS Utility 3 to transfer my images from the EOS R to my iMac (High Sierra) using a USB-cable.I did a clean install of macOS Catalina on my MacBook Pro (mid 2014) and installed the most recent version of EOS Utility 3. When I connect my EOS R with a USB-cable to my MacBook Pro the EOS Utility starts up but does not make a connection with the EOS R.The download link on the Canon website does not yet show macOS Catalina as OS so I used the most recent OS shown in the list (macOS Mojave).Anyone experiencing the same problem?

Or does your Mac have a USB C connection.My MacBook Pro does not have a USB-C port. I use its USB-3 port. I have a cable with USB-C at one end and USB-A at the other end. This worked always flawlessly on my iMac with High Sierra for transferring images.

I now use a USB-A SD-card reader which works fine.I think Canon's software is not yet ready for macOS Catalina. I encountered the same bug in DPP as reported earlier in this forum concerning raw conversion. The option 'Convert and Save' does not work. A way out is using batch processing.

Thank you to all who chimed in. I've been trying to get EOS Utility to work for the past few hours.

In my quest, I came across this that says it works. Of course, we now know that 10.15.2 broke it.I actually don't use EOS Utility. I was trying to use it just to answer some curiosity I had.I have a SD card reader which is USB-3 and my laptop has an SSD with USB-C. I downloaded image from the SD card to the laptop and checked the speed. It was going about 90 MB/s with occasional brief drops down to 60 MB/s.I wanted to see how fast the transfer would be using the camera's hardware since it is newer than my card reader and is native USB-C.Has anyone checked? I'm still curious to know how fast a camera to laptop transfer goes.

I have the same problem on 3 Macs: When I installed Catalina a few weeks ago on my iMac 27 (2017), EOS Utilities 2 and 3 did not connect with my EOS Cameras (6d, 5dii). I reistalled the Utilities and loaded the newest firmware on both cameras – did not work. The same happened on a new MacBook Pro 2019, which was already configured for Catalina (newest version of the EOS utilities installed)On an old MacBook Pro (2013), I was first surprised the the cameras conected to the laptop even after I installed Catalina. However, as there were too many 'leftovers' in the libraries from the many years use, I decided to backup all documents, music, movies, photos etc., strip the library – as time machine used 24 hours for a 120 GB backup! – and completely wipe the250 GB SSD, reinstall Catalina and all necessary drivers and programs. Now – without any docs, media etc – EOS Utilities 2&3 did not connect my cameras to this MacBook anymore.At least there is an uncomfortable, more time-consuming way to download Photos from the SD-Cards to the iMac or the old MacBook (the new one has no card slot).I would needed CompactFlash CF Card Reader to download photos from the EOS 5dii to the Macs.

I have two of these, none of them works. How do I get my EOS 5dii images to a computer?Its not the only caveat after the Apple OS X change to Catalina, which confused and dissappointed many Apple users. How to use vim. Too many 'nice' gadgets, 64 bit only, however, many good programs (.including the Apple iWork suite) are now close to useless, do not work anymore – or you are forced into costly cloud programs!
