OK, you should be able to create a samba.conf from the sample file in the Configfiles directory, adding a block to export the .kodi folder via SMB as well, which I believe is what you are looking for. The "Show hidden files and directories" option within Kodi/LE discloses those files within the Kodi file manager and are NOT related to which files you see on your Mac (those are the SMB exports). Don't know about your old installation but think your new one behaves normally.

I hope the above will give you the hints to solve your issue / customize your system the way you want it. If not, I would propose you create a new discussion on the LE forum. Happy to continue helping you over there, but we are running off-topic here.
