what greeting card software will work with macOS Catalina?

Hello rich_macbook_air and welcome to Apple Support Communities.

I see you have a question about greeting card creation options for a Mac running Catalina.

If you go to the Mac App Store and search the term "greeting cards" you'll find a bunch of app options for that purpose.

Cheers.

I still can't figure out what software is similar to the HP Creations that will work on Mac OS Catalina. I'm willing to buy software but want to make sure I can create greeting cards with photos with the same amount of flexibility I had on HP software. Can anyone help me?

Hi rich_macbook_air.

Happy to help. Enjoy the rest of your day.

Cheers.
