@MarkMLI: see FPC Git Migration on the Wiki.
BTW, I agree. Git (when used as an insult) is a reasonably appropriate name for it which is why sites like this (Warning: Adult Content) and this (same site, but for the more genteel) exist.
[Edit] To continue using svn on macOS, see this thread.
Git certainly has its uses as a way of coordinating distributed development, but I've never been convinced that it is good for the sort of distribution for which FPC and Lazarus use Subversion.
I've seen an interesting case where PCB design software (KiCAD) uses git as the repository for live templates etc., it seems to work but I think Subversion would work equally well.
I've also seen it used as the principal distribution mechanism for Mycroft
https://mycroft.ai/ where arguably it doesn't work: the developers have somehow managed to structure it that you have to pull the entire repository (i.e. depth= can't be used) before anything will work.
So I remain sceptical.
