Nektony has launched Funter 4.0 in the Mac App Store (https://tinyurl.com/y8e8fbwb). It’s a free tool designed specifically to hide and view hidden files and folders on macOS 10.13 or higher.
Funter provides the ability to switch a file or folder visibility in one click, making it hidden or unhidden. The app searches for files in system folders and package contents, even where Spotlight never looks.
