when I download it it isn't zip, but an app. I tried compromising it so it becomes a zip. then I downloaded the app unarchiver. but it says "RickAndMorty_v2_9.zip can't be opened with the unarchiver app
In the menu bar, go Safari -> Preferences. In the "General" tab, uncheck "Open 'safe' files after downloading". This will stop Safari from automatically unzipping the files.
if that doesn't work check your trash my zip files always go there for some reason
