Removing certain files on your MacBook or Mac desktop could feasibly brick your device. It’s because of this Apple hides these files, making them harder to find and delete. And yet, it’s possible to access these files, if necessary. 

Hidden files on macOS Big Sur take many forms. These include libraries and files, backend directories, and more. Altogether, these files efficiently run your system. Apple provides various ways to unhide hidden files on your computer.  This includes viewing them through 'Finder' or using Mac’s 'Terminal' app. 

The average Mac user shouldn't need to delete or modify system files. Keep this in mind before going further. Nonetheless, these directions are useful for developers and anyone receiving tech support from Apple.

1. Using Finder to view hidden files

Using 'Finder' is the easiest way to uncover hidden files. To get started, click the 'Finder' app on the Mac dock. Choose the 'Macintosh HD folder' under Locations on the left side of the 'Finder' window. Next, press 'Command' + 'Shift' + '.' (the period key) at the same time. The grayed-out files are those typically hidden. 

You can perform the same steps in the 'Documents', 'Applications', and 'Desktop' folders. To hide the files once again, press 'Command' + 'Shift' + '.' (the period key) at the same time.

The 'Terminal' app allows you to get text-based access to hidden files. Programmers and developers alike might want to follow these steps. 

To use 'Terminal', click 'Finder' on the dock. Then choose 'Go' from the menu bar, then 'Utilities'. In the 'Utilities' folder, select 'Terminal'. 

Type the following into 'Terminal' then hit the 'Enter' key:

killall Finder

You can now view hidden and temporary files through your Mac's file system. 

When you're finished, you should once again hide these files. To do so, use the following command, then click 'Enter'.

defaults write AppleShowAllFiles false

Next, type this command in Finder, followed by the 'Enter' key:

killall Finder

The files are once again hidden.
