How to Show Hidden Files on MacOS with a Keyboard Shortcut

Modern versions of Mac OS offer a super-fast and easy way to reveal invisible files on a Mac, all you need to use is a keyboard shortcut. With a simple keystroke, you can instantly show hidden files on a Mac, and with another strike of the same keyboard shortcut, you can instantly hide the hidden files again too. This is by far the fastest way possible to show and hide invisible files on a Mac. You won’t need to use the defaults command to show hidden files (though it still works), instead you can just use the handy keyboard shortcut anywhere in the Finder or a file access dialog.

To use the hidden files keyboard shortcut, you’ll need a modern version of Mac OS system software, including macOS High Sierra and macOS Sierra, anything beyond 10.12 should support the invisible files toggle keyboard shortcut.

If you’re unfamiliar with the concept, hidden files and hidden folders on a Mac are typically either system level items, configuration data, or some other file or folder which is usually hidden from the average end user for a reason. Thus, revealing hidden files is usually only necessary for more advanced Mac users, whether it’s to view, edit, or modify some particular invisible file or folder, or contents therein.

How to Show Hidden Files on Mac with a Keyboard Shortcut

Using the Show Hidden Files Keyboard Shortcut is incredibly simple, here’s how it works:

  1. From the Finder of Mac OS, navigate to any folder where there might be hidden files (for example, the Macintosh HD root directory, or a user Home folder)
  2. Finder icon on the Mac

  3. Now press Command + Shift + Period to instantly toggle to show hidden files
  4. Show hidden files on Mac with a keyboard shortcut trick

Here is an example of what the Macintosh HD directory looks like after hidden files are made visible, and after hidden files are made invisible again, this is demonstrated in animated GIF format so that you can see the hidden files appearing and disappearing:

As you can see the hidden files and folders become visible and invisible as the keyboard shortcut is pressed.

The hidden files and folders, often marked as hidden via chflags command, setfiles, or by placing a . period as a name prefix, will instantly become visible. The now visible hidden files will be displayed as having slightly faded names and icons, to offer a visual indicator that the file or folder in question is usually hidden.

Hidden Files are now visible in Mac folder with keyboard shortcut

Note that with hidden files made visible, they will become visible in all folders on the Mac, just like what happens if you use the defaults command to show hidden files in Mac OS and Mac OS X. The big difference between modern Mac OS releases and earlier versions of system software is that now the Command + Shift + Period keyboard shortcut is available to show and hide invisible items in the Finder, whereas before you had to use the defaults write command in the Terminal to reveal or hide those files and folders. If you prefer the command line approach for whatever reason, it is still available to modern Mac OS releases.

And of course you can quickly toggle to hide the hidden files again and make them no longer visible by using the same keyboard shortcut:

  • Navigate anywhere in the Mac Finder and hit Command + Shift + Period again to hide invisible files

Toggling the hidden files keyboard shortcut will impact all folders on the Mac.

Just remember that pressing down Command + Shift + Period in the file system of Mac OS will hide or show invisible files.

The keyboard shortcut to show or hide hidden files on Mac OS

The visual indicator of hidden files and folders is fairly obvious. Here’s a folder (root Macintosh HD) with hidden files invisible, the default state:

And here’s that same folder with hidden files made visible via the keyboard shortcut, as you can see there are many more items in the same directory but they are hidden from the usual Finder view of the user. Each hidden file or folder is represented by the faded opaque icon and name:

If this keyboard shortcut sounds familiar to you and you’re a longtime Mac user, it’s probably because the Command Shift Period trick has long worked to toggle viewing of invisible items in Open and Save dialog boxes, it’s just that now that same keyboard shortcut can toggle the visibility of invisible items in the general Finder of Mac OS as well.

As mentioned before, you can still show and hide hidden files in Mac OS with a defaults command if you want to, or you can enable with a defaults command and hide them again with the aforementioned keystroke, but the defaults string syntax is simply no longer necessary to gain quick access to the hidden files.

Again, this keyboard shortcut trick only applies to modern MacOS releases, earlier versions of system software will need to use the command line method instead.

Whether you show or hide invisible files on the Mac is entirely up to you, but generally speaking having them made visible is most appropriate for advanced Mac users who need to access the hidden directories or files that are scattered throughout Mac OS. Absolutely do not remove, modify, or delete any hidden files without knowing what you’re doing, many of them are configuration files for various apps, programs, and functionalities, or are necessary components to Mac OS and software.
