How to undo hitting no on "import files from computer"

Hi I was recently starting to get into Anki and when I went to import files I accidentally hit no when it asked if I wanted to import files from my computer into anki, therefore not letting me import the add ons. Do you know how I can fix this. I am on a Mac and I have tried to uninstall it and reinstall it, but it seems to save that one setting.
