Problems with synchronization

[Andreas Zerr]

Hi there!

I do have a problem with the synchronization between to computers (MacBook Air and MacBook Pro). While traveling with the MacBook Air I took some 2.000 photos which I have stored on the computer and an external hard drive. Now I want to synchronize the MacBook Air with my studio MacBook Pro, but I simply can't get it to work properly. 

It worked for about half of 30 collections, but it does not want to continue. All files are locally available. When I hit the synchronization button, I am always prompted with the same message: Do you want to stop synchronizing this collection?

All collections have the synchronization button ON.

Does anybody know where the problem might be? There's more than enough space on my CC cloud drive.

Thanks for your support.

Lightroom Classic can only sync one single catalog, so what you are trying to do does not work and is not meant to work. What you need to do instead is open Lightroom Classic with your main catalog on your main computer, and then use 'Import from Another Catalog' and import the catalog from the other computer. https://helpx.adobe.com/lightroom-classic/kb/catalog-faq-lightroom.html

Hi Johan,

Thanks a lot. I do understand what you are saying.

What I don't understand is, why it works for approx. half of the images, but not all. 1.900 photos were synched, but 3.200 photos do have sychronization error, even though there's more than enough space on my CC cloud.

Anyhow, I'll try importing the catalog.

Thanks again.

Lightroom Classic 13.3 has a new synchronization engine, and there are indeed problems with it. Version 13.4 does not fix this yet. But anyway, syncing Lightroom Classic to the cloud is not the way to keep the catalogs on two computers in sync.
