Why does Mac OS hide files or folders?
A hidden file or folder is a file/folder which filesystem utilities do not display by default when showing a directory listing. Mac OS has always hidden some vital files on the startup disk.
You must be wondering, why Apple Inc. doesn't let you see hidden files on Mac? Generally speaking, there are two main reasons:
For security: The main reason is that the core system files need to be hidden so that your Mac can run correctly. It will protect these files from being damaged or deleted by the average Mac user. All the hidden files include preferences, caches, logs, and other service files of the installed apps and the Mac operating system.
For tidiness: Another reason why some files are hidden is that if files on Mac are all visible to you, your computer and the desktop would appear like a mess. Therefore, files that are not used frequently are put out of sight.
However, in some cases, you probably want to find hidden files to troubleshoot apps' errors, to find some lost/disappeared files, or to clear cache on Mac by deleting hidden files for more available spaces. Don't know how to spotlight these invisible files? Don't worry, the following part will go into detail.
