How to Show Hidden Files and Folders on a Mac

macOS usually hides certain files (like system files, caches, and app support data) to keep things tidy and smooth. But sometimes, files can be hidden for other reasons—glitches, accidental changes, or just user settings. We’ve helped plenty of users deal with this exact problem. When you need to see hidden files on your Mac, there are three reliable methods to unhide them quickly. Let’s break them down.

Method 1: Show Hidden Files in macOS Finder

The easiest way to reveal hidden files on your Mac is through Finder. This method is simple, quick, and works for most situations. Here’s how to view hidden files on Mac Finder:

1. Open Finder from your Dock.
2. Go to any folder where you think hidden files might be, like Macintosh HD or Documents.
3. Press Command + Shift + . (period) on your keyboard. This immediately shows hidden files and folders, which appear slightly grayed out compared to regular files.
4. If you want to hide them again, press the same combination once more.

Method 2: Show Invisible Files on Mac with Terminal

When Finder doesn’t do the trick, Terminal gives you another option to unhide files on your Mac. While it’s a bit more technical, we’ve found this method to be a lifesaver with stubborn files that won’t show up otherwise.

1. Open Terminal. Press Command + Space to open Spotlight, then type “Terminal” and hit Enter.
2. Type the following command and press Enter:
   defaults write com.apple.finder AppleShowAllFiles true
3. Then restart Finder:
   killall Finder
   This will force Finder to restart and show hidden files or folders on your Mac throughout the system.
4. To hide the files again, use the same command but change true to false:
   defaults write com.apple.finder AppleShowAllFiles false
5. Once again, restart Finder:
   killall Finder

Still Nothing? Use Data Recovery Software to Find Hidden Files

If you’ve tried Finder and Terminal and still can’t locate those hidden files, third-party recovery software might be your next best option. Tools like Disk Drill are designed to retrieve data that may be lost or deleted—data that can’t be accessed through usual methods like Finder or other file managers. We’ve recommended this option many times for users who need a more thorough scan of their system.

Here’s how you can use Disk Drill to reveal hidden files:

1. Go to the official Disk Drill website and download the software. Follow the installation steps.
2. Open Disk Drill and select the Storage devices tab from the sidebar.
3. Select the drive you want to scan (typically your main Mac drive, but can be any other storage device).
4. Click Search for lost data. The scan will begin, and you can click Review found items even while the scan is in progress. A list of found files will appear, and it will continue to grow as the scan continues.
5. The files will be grouped under different categories like Existing files (files that currently exist on your system but might be hidden), Deleted or lost (files that have been deleted from your system but are still recoverable), and Reconstructed (files that have been partially recovered from fragments found). You can filter the results by file types—such as Pictures, Videos, Audio, or Documents—to make it easier to find what you need.
6. To make sure you see everything, check that Show system & hidden files is enabled. This will display all hidden files within Disk Drill’s interface. Click the Show button and select Show system & hidden files.
7. You can check both files and entire folders for recovery. A preview window will appear for each file, which is super helpful to be sure you’ve found the right files.
8. Click Recover to save these files. Note that the basic version of Disk Drill for Mac lets you scan and preview files, but to actually recover them, you’ll need to upgrade to the PRO version. At least with the free version, you can be sure your files are still there.

Disk Drill is one of the best tools for this kind of task, and we’ve recovered tons of files with it. Its file type support is impressive (everything from popular formats like JPEG, MP4, PDF to more obscure ones like RAW, FLAC, and MAT.) It also works flawlessly on macOS, even with the newest macOS Sequoia. If you want to compare it with other tools, check out our list of the best data recovery software for Mac.

To Sum Up

As you can see, there’s nothing complicated about hidden files on your Mac. Whether you go with Finder, Terminal, or Disk Drill, each method fits different situations.

Use Finder for quick access, Terminal when Finder doesn’t work, or Disk Drill for a deep scan and file recovery. Just remember, hidden files are often important for system operations, so be cautious.

By the way, if you’re sure certain files shouldn’t have been hidden, it might be a good idea to check your Mac or storage device for viruses. Malware has been known to hide files, manipulate directories, or cause data to disappear unexpectedly.
