Catalog Backup on a Mac

[JACK LARSON]

I installed the latest version of LRCC.  When I tried to Backup my Catalog, I got a dialog saying that my Catalog was larger than 4 GB  (mine is 4.55 GB) and that I needed an app such as Stuff It.  I did install Stuff It 16 for Mac, but I don't know how to use it.  I don't want to screw up my Catalog.  Exactly what do I do?  Thanks.

Is it the same problem shown in this thread?

Catalog size warning is not correct.

Catalogs larger than 4GB are now zipped again, but they’re too big for macOS to unzip natively, so you’ll need 7-zip or StuffItExpander if you need to restore a backup.
