Lightroom Classic: Another Tethering issue with Canon 5D Mark IV and macOS Catalina 10.15.4

I am trying to shoot tethered, and having some frustrating issues. I would greatly appreciate any help! 

I have a Canon 5D Mark IV (latest firmware), Tether Pro by Tether Tools USB C Cable, iMac and Macbook Pro both running Catalina 10.15.4, and Lightroom Classic 9.2.1 release (latest update).

When I connect my camera I can see on the LCD screen that the camera recognizes it is connected to a computer. Canon's EOS Utility 3 then starts to open automatically. I can use this utility to shoot tethered just fine, all functions seem to be working. 

If I open Lightroom Classic and try to start a tethered session the software says no camera is detected. I managed to get it to work one time briefly on the iMac, but never on the Macbook Pro. 

I have rebooted the computers, cycled power to the camera, unplugged and plugged in the USB cable and I have had no luck. 

Any help would be greatly appreciated!!

If anyone from Adobe is seeing this, why don't you guys have tethering support in Lightroom CC?

From your description, I am guessing that the EOS utility 3 is interfering. 

Load Image Capture (macOS)
Select your 5DMKIV
In the lower left select "Do Nothing/No Application" so that EOS Utility doesn't load when connected.
Reboot and try again.

Rikk,

Thank you for the quick reply. I agree that EOS Utility seem to be interfering. I did a couple of things.

1. I did go find and delete the Lightroom preference file on both computers. 
2. Made sure that "no application" was selected in "Image Capture" on both computers and then did a reboot.

When I connect the camera, EOS Utility still opens! lol Grrrr

On the iMac I was able to start Lightroom Classic and attempt to start a tether, no camera detected. Next I went over to EOS Utility and told it to quit, once I did that Lightroom found the camera and everything works. 

Attempted the same steps on the Macbook Pro, no luck, nothing, Lightroom Classic never detects the camera. 

Of course my end preferences for shooing tethered is using Lightroom and the Macbook Pro. The iMac, while it seems to work now, is not "mobile".

Check EOS utility to make certain there is no preference that allows you to disable its launch at load. 

On your MBPr, the right side USB port is problematic. Try using the left side.

I tether with EOS-R (basically a mirrorless 5DMkIV) and a 5DS-R.  I'm NOT using Catalina yet.  I have similar issues.  It has to do with conflicts with EOS Utility.  There is a preference in EOS Utility telling it not to auto launch when a camera is detected.  With that set it still autolaunches from time to time.  I have it set to show in the menu bar.  If I see it there, I know that it autolaunched.  If i just quit it from there... Lightroom tethering works just fine.  EOS Utility is handy for certain situations.  I don't want to just uninstall it..  Its fairly easy to deal with now that I know the problem.  Hopefully this is what's going on with your system as well.

I agree with what Rikk said about using specific ports.  I have a 2017 13" MacBook Pro.  On my system its not a left/right thing but certain ports work well for certain devices and not others.  I have them labeled to alway plug picky devices into the same port. (('m sure this has NOTHING to do with the fact that a serious coffee spill occurred in my laptop bag a few years ago :-) )
