Hidden files and folders are an important part of macOS. They store system settings, application data, configuration files, and other information that helps your Mac function properly. While these files are hidden by default to prevent accidental changes, there are times when developers, power users, or anyone troubleshooting an issue may need to access them.

In this guide, we'll cover three easy ways to reveal hidden files and folders on your Mac.

Method 1: Use the Finder Keyboard Shortcut

The quickest way to show hidden files is by using a built-in Finder shortcut.

1. Open Finder.
2. Navigate to any folder.
3. Press Command + Shift + . (period).
4. Hidden files and folders will immediately appear as translucent items.
5. Press the same shortcut again to hide them.

This method is ideal when you only need temporary access to hidden files.

Method 2: Show Hidden Files Using Terminal

If you prefer using Terminal, you can configure Finder to always display hidden files.

Open the Terminal application and run:

defaults write com.apple.finder AppleShowAllFiles true
killall Finder

Finder will restart, and all hidden files will become visible.

To hide them again, run:

defaults write com.apple.finder AppleShowAllFiles false
killall Finder

This approach is useful if you'll be working with hidden files frequently.

Method 3: Access the Hidden Library Folder

The user's Library folder is hidden by default but is commonly used for application settings and caches.

To access it:

1. Open Finder.
2. Click Go in the menu bar.
3. Hold the Option (Alt) key.
4. Select Library from the menu.

This is the safest way to access the Library folder without changing Finder's display settings.

Things to Keep in Mind

Although hidden files are accessible, many are essential for macOS and installed applications. Avoid modifying or deleting files unless you understand their purpose, as doing so may cause applications or the operating system to behave unexpectedly.

For most users, the Finder keyboard shortcut is the easiest and safest way to temporarily reveal hidden files whenever they're needed.
