I get this message:
The Lightroom catalog cannot be used because the parent folder “/Volumes/Fotos Jorge/Lightroom Disco Externo” does not allow files to be created within it.
Thread moved to Lightroom Classic.
It sounds like you have some kind of permissions problem. The most likely fix... go to System Preferences > Security & Privacy > Privacy tab > Files & Folders (on the left) > find Lightroom and make sure all of the checkboxes are checked.
To build on this, Apple changed something in its draconian security rules in Mac OS 12.3.1 and many, many people here are experiencing a range of bad symptoms, requiring LR have Full Disk access (which was never required before). See this article for how to grant Full Disk Access:
Thank you John. This worked great.
