Hidden files and folders on a Mac are typically system folders that contain vital data that your macOS needs, and are hidden from view for security and tidiness reasons. Although you might not need access to these files regularly, you might need them to fix an issue, delete a preferences file for an application, or modify your system.
Locating hidden files and folders can be difficult, but we have you covered with several methods, including using Finder, Terminal, or third-party applications.

What are hidden files and folders?
Hidden files and folders are files and folders that are hidden by default on a Mac to prevent users from unintentionally deleting or modifying them. These files typically hold important system settings and preferences that are necessary for your operating system to operate properly.
The Library folder is the location that contains these important system files and settings for both the operating system and the downloaded apps. By first finding the Library folder in the user’s Home folder, you can find these files in the Library folder. To do this, follow these simple steps:
- Open Finder on your Mac
- Select “Go” from the Finder menu bar, and then “Go to Folder…”.
- Type “~/Library” (without quotes) in the dialog box, and click “Go”.
As a note of warning, accidentally deleting or changing these files in the Library folder can create issues with your computer’s software and Mac operating system. Since there may be risks involved, it is best to view these with caution and to avoid making any modifications inside the Library subdirectory unless you are familiar with the working of Mac operating systems.
What kind of files are hidden from being seen on Mac?
Many different types of files and folders are typically hidden in the Finder by default or blocked from being seen. Some examples include the following.
System Data: These files, which include kernel extensions, drivers, and system setup files, are necessary for your Mac operating system to operate correctly.
Preferences: These are files that contain the operating system and application system preferences. Typically, these include network settings, user interface settings, and application-specific settings.
Caches: Applications and the operating system generate caches, which are temporary files, to improve efficiency. They consist of items like system caches, font caches, and online browser caches.
Log files: These files store details about system actions and events, including performance statistics and error messages. They are frequently used by programmers and help staff to solve issues.
Hidden Directories: Hidden folders are used by the operating system and apps to keep files but are invisible to the user in the Finder. For instance, the “Library” directory, which by default is hidden, holds important system data and configurations.
Again, all these files are hidden by default to avoid accidental changes or deletions because any change to them can affect how well your Mac’s operating system performs and functions. Users still have access to these files and the ability to alter them if strictly required.
How to show hidden files with Finder
Using ‘Finder’ is the easiest way to uncover hidden files. To get started, simply follow these steps:
- Open Finder by clicking on the icon in the Dock or by pressing Command + Space. Type “Finder” into Spotlight, then press Enter.
- You can access User Folder by clicking on “Go” and choosing “Go to Folder” or pressing Command + Shift + G. Click on “Go to Folder” and type /Users/[username]/. Replace “[username]” and then press Enter with your Mac username.
- You can show hidden files by pressing Command + Shift + Period (.) or by clicking “View” in the Finder menu and selecting “Show Hidden Files”. The current directory will display all hidden files.
- If you want to hide hidden files again, press Command + Shift + Period (.) or click on “View” in the Finder menu and deselect “Show Hidden Files”.
As a pro tip, you can recognize hidden files and folders by looking for files and folders that have a dot (.) at the beginning of their name. Hidden files and folders are frequently titled with a dot (.) at the beginning of their name.
If you’d rather use Terminal, launch it, browse to the folder where you want to look for hidden files and folders, and then enter “ls -a” to see a list of all files and folders in the current directory, including hidden files and folders.
