Installers aren’t really the preferred way to distribute software on a Mac, unless you need special access to the system for some reason. Most Mac software is distributed as an application bundle that’s dragged wherever you want on the file system and then run by double-clicking.

I would go as far to say that a good chunk of more technically inclined Mac users have a tendency to view any user facing software that requires an installer with suspicion.
