I just received a new MacBook Air with 10.14.5 and Calibre runs, but won't open. I thought maybe I had a version of Calibre that doesn't work with the latest OS so I relabeled the old file and downloaded a new one. It still runs, but won't open. I don't see it running when I pressed the F3 key.

I saw an old post about plugins causing a problem, but I think it wasn't Calibre plugins, but Mac ones. I do have several plugins in Calibre and they're pretty old, but they didn't cause a problem running on my old Mac.

As you can see, I'm not a software engineer, but my daughter-in-law is. I'd rather fix it myself, though. If you can tell me in plain language how to fix this or say something magical my DOL will understand I would really appreciate it.
