I can't answer Moved vs Copy action you did
Also copy the config folder (not a MAC person, but preferences Misc...: open config folder should take you there
OK
What I would do
Install Calibre on your new MAC (
DO NOT ADD ANY BOOKS)
Shut Calibre down
REPLACE the config folder with the old one (that does all your PI and settings. in 1 Bang)
REPLACE the
contents of the Library folder with the
contents of the old. You may need to point Calibre to the new path when you start. on Library Icon: Switch/Create: USE EXISTING : <point it to the new folder>
(if both Library folders have the same, default name, replace the folder.)
