As a Mac user, you might have encountered situations where you need to access hidden files or folders on your computer. By default, macOS hides certain files and folders from view to keep your file system organized and prevent accidental deletion of critical system files. However, there are times when you need to access these hidden files to troubleshoot issues, edit system settings, or even recover deleted files. In this comprehensive guide, we’ll show you how to show hidden files on Mac using various methods.
Why Are Files Hidden on Mac?
Before we dive into the methods to show hidden files, let’s understand why files are hidden on Mac in the first place. Apple’s macOS operating system hides files and folders for several reasons:
Security: Hiding critical system files and folders prevents users from accidentally deleting or modifying them, which could compromise the system’s stability and security.
Organization: Hiding unnecessary files and folders helps keep your file system organized and clutter-free, making it easier to find the files you need.
Performance: Hiding files and folders can improve system performance by reducing the number of files the operating system needs to process.
Method 1: Using the Finder Menu
One of the simplest ways to show hidden files on Mac is to use the Finder menu. Here’s how:
Step-by-Step Instructions:
- Open the Finder app on your Mac. You can do this by clicking on the Finder icon in the Dock or by pressing Command + Tab to switch to the Finder app.
- Click on the “View” menu at the top of the screen.
- Select “Show View Options” or press Command + J.
- In the View Options window, enable the “Show Hidden Files” checkbox.
- Click on the “Use as Defaults” button to apply the changes to all folders.
Note: This method only shows hidden files and folders in the current folder. If you want to show hidden files system-wide, use the Terminal method described later in this article.
Method 2: Using the Terminal App
The Terminal app is a powerful tool that allows you to access and manipulate system files and settings using command-line interfaces. To show hidden files using the Terminal app:
Step-by-Step Instructions:
- Open the Terminal app on your Mac. You can do this by searching for “Terminal” in Spotlight or by navigating to Applications > Utilities > Terminal.
- Type the following command and press Enter:
defaults write com.apple.finder AppleShowAllFiles -boolean true - Restart the Finder app by typing
killall Finderand pressing Enter.
Note: This method shows hidden files system-wide, but it requires some technical expertise and caution when using the Terminal app.

Another way to show hidden files on Mac is to use the command line in the Finder app. Here’s how:
Step-by-Step Instructions:

Note: This method only shows hidden files and folders in the Home folder. To show hidden files system-wide, use the Terminal method described earlier.
Method 4: Using Third-Party Apps
If you’re not comfortable using the Terminal app or command line, you can use third-party apps to show hidden files on Mac. Here are a few popular options:

By following these tips and precautions, you’ll be able to show hidden files on your Mac safely and efficiently.
What is the purpose of hiding files on Mac?
Hiding files on Mac is a security feature that allows users to conceal sensitive or confidential files from prying eyes. This feature is useful for individuals who share their Mac with others or have sensitive information that they want to keep private. When files are hidden, they are not visible in the Finder, making it difficult for others to access them.
By hiding files, users can protect their sensitive information from being accidentally deleted, modified, or accessed by others. Additionally, hiding files can also help to declutter the Finder and reduce visual clutter, making it easier to focus on important files and folders.
How do I know if I have hidden files on my Mac?
If you’re not sure whether you have hidden files on your Mac, you can check by using the Terminal application. To do this, open the Terminal app and type the command “ls -a” (without quotes) in the command line. This will display a list of all files and directories in the current directory, including hidden files. Look for files or directories with a dot (.) at the beginning of their name, as these are typically hidden files.
Alternatively, you can also use the Finder to check for hidden files. To do this, press the Command + Shift + Period (.) keys simultaneously to toggle the visibility of hidden files. If you see any files or folders that you didn’t know existed, they may be hidden files.
Why can’t I see hidden files in the Finder?
By default, the Finder does not display hidden files or folders. This is because hidden files are intended to be concealed from view, and the Finder is designed to only show files and folders that are not hidden. However, you can easily toggle the visibility of hidden files in the Finder by pressing the Command + Shift + Period (.) keys simultaneously.
To permanently show hidden files in the Finder, you can modify the Finder’s preferences. To do this, go to the Finder’s menu bar, select “Finder” > “Preferences”, and click on the “Advanced” tab. Then, check the box next to “Show all filename extensions” and close the preferences window.
Is it safe to show hidden files?
Showing hidden files is generally safe, as long as you’re aware of the potential risks. When you show hidden files, you may see system files and directories that are essential to the operation of your Mac. Accidentally modifying or deleting these files can cause problems with your Mac’s performance or even render it unusable.
However, as long as you’re careful not to modify or delete system files, showing hidden files is relatively safe. If you’re unsure about what a particular file or folder is used for, it’s best to leave it alone.
Can I hide files again after showing them?
Yes, you can easily hide files again after showing them. To do this, simply press the Command + Shift + Period (.) keys simultaneously to toggle the visibility of hidden files. Alternatively, you can also use the Terminal command “chflags hidden” (without quotes) to hide a specific file or folder.
Note that when you hide files again, they will be concealed from view in the Finder, but they will still be accessible using the Terminal or other command-line tools.
Are hidden files the same as system files?
No, hidden files are not the same as system files, although some system files may be hidden. Hidden files are any files or folders that have been specifically marked as hidden, either by the user or by the system. These files can be anything from user data to system configuration files.
System files, on the other hand, are files and directories that are essential to the operation of your Mac. These files are typically hidden from view, but they can be accessed using the Terminal or other command-line tools. System files are usually owned by the system and should not be modified or deleted, as this can cause problems with your Mac’s performance.
Can I hide entire folders or just individual files?
You can hide both entire folders and individual files on your Mac. To hide an entire folder, simply right-click (or control-click) on the folder and select “Get Info”. Then, check the box next to “Hidden” in the “Get Info” window.
To hide individual files, you can follow the same steps as for hiding folders. Alternatively, you can also use the Terminal command “chflags hidden” (without quotes) to hide a specific file or folder.
