Also, I'd like to use an alias and not have my real name visible in the forum.
Copied my zotero folder and its contents from my old computer (Win xP) to my new Mac running Catalina. I can see my collection folders online, but nothing in my Mac stand-alone version. Report ID: 568443763Steps to reproduce:1. Copy old Zotero folder to correct location /users/mynamehere/Zotero2. Quit Zotero and Chrome3. restart Mac and Zotero stand-alone4. When I click on the brown My Library folder, I get a message: Welcome to Zotero! but my collections are not there.5. When I go online, they are all there.Note: I have not used Zotero for a few years, but I did not remove anything.How do I access my collections? The Zotero folder I copied to my Mac has all the pdf articles that are not online, so I need to be able to access them.
