This will be the third time that I have tried to correctly install Lazarus, FPC, and the respective packages; I really want this to be the last time. I just want to teach myself Object Pascal.
I must say here that I am not a big fan of the 'reinstall model' - especially when it becomes a habit. There is no intrinsic reason why you should need to reinstall. Yes, I know is necessary with Windows because of the DLL mess but MacOS is, sort of, Unix. My point is that it would be nice to workout why this is necessary before reinstalling, Otherwise, we risk having to do it again !
So, just in case you have not yet begun ...
Concentrating on this issue that Trev brought up, why fppkg is unconfigured (just as somewhere to start) fppkg has a config file, fppkg.cfg. On my Linux box, it lives in ~/.config and maybe there on the mac too, given that the mac install does try to lever its Unix-ness as much as possible. So, please try this in a terminal in your home directory -
find . -name fppkg.cfg [enter]
If that does no find anything, and you have some time to spare -
find . -name fppkg.cfg 2>/dev/null [enter]
If you do find it, please cat it out and see if it contains sensible data, should be human readable in an ini file like format. If, as seems likely it might be there but corrupted. Unlikely its not there at all ....
