Any Apple Silicon Mac users using 10.8.13 or 10.9?

There is indeed a bug in the migration code.

For current workaround, you can do this:

Go to ~/.local/share, move the jellyfin folder to ~/Library/Application Support/. Make sure that the jellyfin folder does not exit in ~/.local/share and is present in ~/Library/Application Support/.

You can go to these folders by pressing command+option+G and paste the path.

We will update the tray app soon so this never happens again

I've already done a manual migration like that and it seems to work for playback and most things, but I couldn't access the library path so I rolled it back.
Adding libraries or scanning existing libraries didn't work.
"there was an error adding the media path. Please ensure the path is valid and Jellyfin has access to that location."
