P: Fails to import photos and stalls out on macOS 10.15 Catalina

Victoria, I am subscribed to your work. Please take a look at my comment below. Any advice much appreciated. 

Like Zach above, I updated to OS X 10.15 Catalina and it was a major upgrade requiring over 8GB HD space. It is awful. I use LR Classic Desktop (v.8.4.1) on my MacBook Pro and now, I can no longer preview images when the SD card is inserted and you click 'import'. This issue has never occurred. With trial and error, I found alternative ways to click through and managed to preview the image files. But when you change the SD card, the pathway was lost and I could no longer preview anything making importing impossible.

However, on LR (Cloud version) on my MacBook, preview is possible with exactly the same SD card inserted. 

I have several mac, all runs OS Catalina.
Lightroom on my Imac will not importing my files and having same problem as Zach.
However on my Macbook Pro 2013 i7 it works..

I hope for a update soon to get it work as before, in meantime I import photos on my Macbook, export them as catalogue, then import them from same catalogue. It worked for me... 

You're right about Adobe's communication skills, Jerry!  But just like you have to be your own medical doctor in this life (with help from real doctors), you have to either be your own IT guy, or HIRE your own real IT guy to help you occasionally, like most companies.

It ended up just being a slow download. All is fine.

To be fair, not every person is an IT professional or tech-savvy so it should not be an assumption that people should simply "know better". Also, Adobe should send out a newsletter to all its' customers(they have our emails). They published a post on here and of course, only people that are signed up to this forum(if they have notifications turned on) would have seen it. Adobe's communications skills have always been noted for being really bad. 

Bonus inquiry. You “restarted the system and program along along with the camera”

Are you connecting the  camera to the computer to import those photos? 

Try a card reader

Would not be at all surprised if Catalina might have issues with an attached device, in that case your camera.

Actual inquiry

1 Photo shoot

Is this particular photo shoot a larger set of photographs to import than normal. Importing 1000 photos takes more time than 200, and the difference may not be linear.

Is this particular photo shoot involving RAW as opposed to in camera JPEG

2. Hard drive space

The hard drive your catalog is on. How much space remains free? Needs to be at least 20%

Did that upgrade eat up lots of start disk space and not free it up after the upgrade?

Venting

Why are so many Adobe customers going all first implementer and upgrading to Catalina v1 

Adobe has publicly recommended we do not do this

Various Tech Reporters have recommended waiting. 

Standard industry (I.T.) practice is never ever install v1 on critical computers

Congrats, you are now an Apple Beta round 2 tester

Could be an issue with the card reader. it happened to me once. i thought there was a problem with lightroom. Figured out that my card reader was damaged and had been pretty slow. It would just keep hanging. Changed it and everything went fine.
