P: Tethering from Canon cameras doesn't work on macOS Catalina 10.15.2

Try the Lightroom Clean Install Procedure with the current version:

• Close Lightroom
• Restart the computer
• Use the Adobe Creative Cloud App to uninstall Lightroom Classic
• Restart the computer
• Install Lightroom Classic via the Creative Cloud App without launching any other programs.
• Restart the computer
• Launch Lightroom
• Wait 5 minutes

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.

Reset Procedure:
1. Close Lightroom.
2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.
3. Overwrite the Preferences when prompted by the dialog.
4. Close Lightroom.
5. Restart Lightroom.
Does the tether issue continue after resetting the preferences?

Not an ideal workaround, but can you use EOS Utility to shoot into a watched folder, then get Lightroom to import from the watched folder. I remember doing this years ago when Lightroom hadn't yet updated for my latest body.

Hi Rikk
Thanks for the advice. I have done all this. Uninstalled and re-installed Lightroom. Tried both my cameras, different leads, enabled logging in tethered preferences but still no luck? Yes before I installed Catalina tethered capture had worked for years on this Mac and with these cameras - I'm a professional so have used it regularly for many years. My camera and lead works fine with EOS Utility so it's not the camera or lead. I'm not sure what else to do other than go for Capture One since I really need to shoot tethered again?

@Andrew Porter:

Have you:

Reset the Preferences file?
Performed a clean reinstall of Lightroom Classic?
Been through the troubleshooting tips at this document? https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-tethered-capture-lightroom.html

Many users are reporting fixed by the recent Mac OS update.  I am guessing you may have a different or additional issue that is preventing tethering from working. 

Did it ever work for you before?

I have done the update to 10.15.3 and tethered works again
Thanks everyone
 

Upgarde to macos 10.15.3 - tethering working again

Should I contact Adobe support again - I have done this several times and they just say I have to wait until Lightroom releases an update?

Hi there, Thanks I have done all this but still no tethering. No camera recognised in tethering bar - just apple spinning wheel. I have tried with both my Canon 5d Mark iv and Mark iii cameras - both dont work!

In some scenarios, a permission issue can happen. That shouldn't be the case with Canon tethering. Nevertheless, could you please check if Lightroom Classic has all required permissions?

1. Go to System Preferences > Security & Privacy.
2. In the Privacy tab, select Security.
3. Ensure that Lightroom Classic has permission assigned to Photos, Full Disk Access, and Files and Folders.
4. Restart Lightroom Classic.

Do you see the Tether bar? Or is it just the Detecting Camera window?

If you see Tether bar, please enable logging:

1. Press the ALT key while the Tether bar is displayed.
2. Select the second Settings icon appears.
3. Select Enable Logging.

This should create some logs in the Documents/LrClassicLogs folder.
I will contact you off list to get the logs.

Thanks,
Sunil

I can confirm tethering with canon EOS 5Dsr working with Lightroom and MacOS 10.15.3 - finally
