macOS hides some files and folders by default because they store app settings, system resources, caches, logs, or other data that most users do not need to edit. These items may appear greyed out or start with a dot, such as .DS_Store or .Trash.

If you only need to view hidden files on Mac, the fastest method is to open Finder and press Command + Shift + Period. If you need to open the hidden Library folder, use the Finder Go menu and hold Option. If the files are missing after you reveal hidden items, they may be deleted rather than hidden, and you may need Trash, Time Machine, or Recoverit to recover them.

Note: Viewing hidden files is usually safe. Editing, moving, or deleting hidden system files can break apps, damage settings, or cause macOS issues.

Why Are Some Files Invisible on Mac?

Some files are invisible on Mac because macOS and apps use them to store preferences, caches, indexes, support data, folder settings, or system-level resources. Many hidden files start with a period, such as .DS_Store, while some folders, such as ~/Library, are hidden from the normal Finder view to reduce accidental changes.

These files are hidden to keep everyday browsing clean and to protect important system or app data. A typical user can view them for troubleshooting, cleanup, development, or app support tasks, but should not edit or delete them without knowing what they do.

App settings: Hidden folders may store preferences, login data, plugins, caches, and support files.
System stability: Changing hidden system files can affect macOS, Finder, or installed apps.
Privacy and organization: Hidden items can keep technical files out of normal folders while still letting apps use them.
Troubleshooting: Advanced users may need hidden folders to reset app settings, remove leftovers, or inspect logs.

Note: If you are not sure what a hidden file does, copy it to a backup location before changing it, or leave it untouched.

Hidden Files vs Hidden Photos vs Deleted Files: What Is the Difference?

What You Want to Find	Where It Usually Is	Best Method
Hidden files in Finder	Folders, desktop, external drives, or system locations	Press Command + Shift + Period in Finder.
User Library folder	`~/Library`	Open Finder, click Go, hold Option, then choose Library.
Hidden photos and videos	Photos app Hidden album	Open Photos and choose View > Show Hidden Photo Album.
Filename extensions	Visible file names such as `.jpg` or `.pdf`	Open Finder settings and enable Show all filename extensions.
Deleted or missing files	Trash, Time Machine, backup drive, or recoverable disk space	Check Trash and backups first, then scan with Recoverit if needed.

How to Show Hidden Files on Mac

You can reveal hidden files on Mac with Finder, the Go menu, Terminal, the Photos app, or a third-party utility. Start with Finder because it is fast, reversible, and does not permanently change system behavior. Use Terminal only when you need a Finder-wide setting that stays enabled until you turn it off.

Method 1. Show Hidden Files on Mac Using Finder

The Finder shortcut is the simplest way to see hidden files on Mac. It works in the folder you are viewing and can be toggled off with the same keys.

Open Finder: Click the Finder icon in the Dock.
Go to the target folder: Open the folder where you expect hidden files to be located.
Reveal hidden files: Press Command + Shift + Period.
Check the results: Hidden files and folders usually appear dimmed or greyed out.
Hide them again: Press Command + Shift + Period again when you are done.

Note: If a file still does not appear after using the Finder shortcut, it may be deleted, stored in another account, located in a different folder, or hidden inside an app-specific library.

Method 2. Open the Hidden Library Folder on Mac

The user Library folder, shown as ~/Library, stores app support files, preferences, containers, caches, fonts, logs, and other user-level data. It is hidden by default because changing the wrong file can affect apps or settings.

Open Finder: Click the Finder icon in the Dock.
Use the Go menu: Click Go in the menu bar.
Reveal Library: Hold the Option key until Library appears in the menu.
Open Library: Click Library to access ~/Library.

You can also open Finder, choose Go > Go to Folder, type ~/Library, and press Return.

Method 3. Show Hidden Photos on Mac

Hidden photos are different from hidden Finder files. Photos and videos hidden in the Photos app are stored in the Hidden album, not as normal Finder items.

Open Photos: Launch the Photos app on your Mac.
Show the Hidden album: In the menu bar, choose View > Show Hidden Photo Album.
Open Utilities: In the sidebar, go to Utilities and click Hidden.
Unlock if required: Use your Mac password or Touch ID if the Hidden album is locked.
Unhide items if needed: Select the photos or videos, control-click them, and choose Unhide.

Note: On macOS Ventura and later, the Hidden album is locked by default and requires authentication before you can view hidden photos or videos.

Method 4. View Hidden Files on Mac Using Terminal

Terminal can make Finder show hidden files across Finder windows until you turn the setting off. Use this method only if you are comfortable running commands on macOS.

Show Hidden Files with Terminal

Open Terminal: Press Command + Space, type Terminal, and press Return.
Run the show command: Enter defaults write com.apple.finder AppleShowAllFiles -bool true.
Restart Finder: Enter killall Finder.
Check Finder: Hidden files should now appear in Finder windows.

Hide Hidden Files Again with Terminal

Run the hide command: Enter defaults write com.apple.finder AppleShowAllFiles -bool false.
Restart Finder: Enter killall Finder.

Note: Do not copy a leading $ into Terminal. The dollar sign is often used in tutorials to represent a command prompt, not part of the command.

Method 5. Unhide Files Using a Third-Party App

A third-party utility can be useful if you frequently switch hidden files on and off or prefer a menu bar toggle. For occasional use, Finder is usually enough. If you choose a third-party app, download it from the developer's official website and review the permissions it requests.

Download the app: Install a trusted Mac utility that can show hidden files.
Open the utility: Launch the app and find its menu bar or Finder control.
Enable hidden files: Turn on the option to show hidden files.
Grant permissions carefully: If macOS asks for Finder, System Events, Accessibility, or Full Disk Access permissions, allow only what you understand and need.
Turn the option off when finished: Hide hidden files again after troubleshooting.

Note: A third-party app is not required to view hidden files on Mac. Use it only when the convenience is worth the extra permissions.

If you used the methods above and still can't see your hidden files, they might not be hidden—they might be deleted or lost due to system errors. In this case, you need a data recovery tool to scan the drive deeply.

Method 6. Recover Missing or Deleted Hidden Files on Mac

If you used Finder, Library, Photos, and Terminal methods but still cannot find the file, it may be deleted or lost rather than hidden. Start with built-in recovery locations, then use Recoverit if the file is not available in Trash, Recently Deleted, or backups.

Check Built-in Recovery Options First

Trash: Open Trash from the Dock and restore recently deleted Finder files if they are still there.
Photos Recently Deleted: In Photos, open Recently Deleted under Utilities and click Recover for deleted photos or videos.
Time Machine: If you use Time Machine, browse the backup date before the file disappeared and restore it.

Recover Missing Hidden Files with Recoverit

Install Recoverit: Download and install Wondershare Recoverit on your Mac.
Select a location: Open Recoverit, click Hard Drives and Locations, and select the drive or folder where the hidden file was lost.
Scan the location: Start the scan and wait while the software searches for deleted, lost, or formatted data.
Use filters: Filter by file type, file name, date, file size, or deleted file status to narrow the results.
Preview the file: Click Preview to confirm the file before recovery.
Recover safely: Click Recover and save the file to a different location from where it was lost.

Note: Do not save recovered files back to the same folder or drive where they were deleted. Saving to a different location helps avoid overwriting other recoverable data.

Common Hidden Files and Folders on macOS

Hidden File or Folder	Common Location	Purpose	Safe Action
`~/Library`	User home folder	Stores user app settings, containers, caches, logs, fonts, and support files.	View for troubleshooting; avoid deleting unknown folders.
`/Library`	Macintosh HD	Stores shared app support files and system-wide resources.	Edit only when following trusted app support instructions.
`.DS_Store`	Many Finder folders	Stores Finder folder view settings.	Usually safe to ignore.
`.Trash`	User home folder or external drives	Stores deleted items before Trash is emptied.	Use the Trash interface instead of editing this folder manually.
`.localized`	System and app folders	Helps Finder display localized folder names.	Do not delete.
`/private/var`	System area	Stores logs, temporary files, caches, and runtime data.	Avoid manual changes unless you know the exact purpose.
`.TemporaryItems`	Drives or folders	Stores temporary files created by macOS or apps.	Do not use it as normal storage.

What to Do If Hidden Files Still Do Not Show on Mac

Problem	Likely Cause	Fix
Command + Shift + Period does nothing	The Finder window is not active, or the keyboard shortcut is being captured by another app.	Click the Finder window first, then press the shortcut again.
The Library folder does not appear in the Go menu	The Option key is not being held while the Go menu is open.	Open Go, hold Option, then click Library, or use `~/Library` in Go to Folder.
The Hidden album is missing in Photos	The Hidden album is hidden from the Photos sidebar or locked.	Choose View > Show Hidden Photo Album, then unlock it if prompted.
Terminal command did not work	Finder was not restarted, or the command was copied with extra characters.	Run `killall Finder` and make sure the command does not include a leading `$`.
The file is still missing after all hidden-file methods	The file may be deleted, moved, stored in another account, or excluded from the current app library.	Check Trash, Recently Deleted, Time Machine, Spotlight, and Recoverit.

Conclusion

The fastest way to see hidden files on Mac is to use Finder and press Command + Shift + Period. For the hidden ~/Library folder, use the Finder Go menu with the Option key. For hidden photos, open the Photos app and use View > Show Hidden Photo Album.

If a file still does not appear after you reveal hidden files, it may be deleted or missing rather than hidden. Check Trash, Photos Recently Deleted, Time Machine, and backups first. If those options do not work, Wondershare Recoverit can scan your Mac for deleted or lost files.

Hidden files are often important to macOS and installed apps, so view them carefully and avoid changing or deleting anything unless you understand its purpose.
