Suddenly having very slow camera connection after upgrading to Lightroom Classic 12 and Mac Ventura

Okay. I am also finding that Ventura doesn't want to mount either the camera as a drive or even the camera disk in a disk reader as a drive.

There have been lots of problems reported with importing and tethering to cameras connected via USB in LR 12 on Mac OS 13 -- Apple changed something that's created lots of issues for LR.  Most of the reports were for Nikons and Iphones, and Adobe has released fixes that appear to help many of those with the problems.

I found several reports about problems tethering Canons and three people reporting problems importing from USB-connected Canons:

If the problem were striking most Canon users, we'd see a flurry of reports here, and Adobe would be able to quickly reproduce the problem. But given the small number of reports, it appears to be something specific to particular configurations or cameras.  So unless Adobe is able to reproduce the problem easily or there are many more reports, I think, based on past experience, that there won't be a fix any time soon.

A couple of suggestions:

- Make sure that you've granted Full Disk Access (not Files And Folders) permission to LR:

Probably won't help, but LR requires Full Disk Access, so it's good hygiene to verify,

- Try a different USB cable.

- Try the Canon EOS Utility to download the photos to your hard drive and then import them into LR from there.

- Use a card reader instead of a cable.  I know it's frustrating to hear that, but importing via a card reader is generally faster than using a cable, and Adobe, Apple, and Windows are no longer providing good support for importing via a cable.

p.s.: I now realize that Lightroom is also not eliminating the "suspected duplicates" from the Import.
