Setting up a new machine running an older Mac OS 10.15.7 Catalina.

- If you are using macOS older than 11.0 (Big Sur), the last version of calibre that will work on your machine is 6.11
- If you are using macOS older than 10.15 (Catalina), the last version of calibre that will work on your machine is 5.44
So, for running in Catalina 10.15.7 itself, just to be sure, does that mean Calibre v 5.44 or 6.11 ?
Thanks.
