Yes, deleting temporary files is an excellent, completely free way to remove junk files on Mac and free up storage space. 

Temporary files (also called "temp files" or "cache files") are created by apps and macOS itself to help things run faster. For example, when you visit a website, your browser saves images and data locally so the next visit loads quicker.

Here's the problem: Over time, these files pile up—sometimes taking up dozens of gigabytes—and your Mac may slow down because the storage is nearly full.

Before you remove junk files on Mac, back up your Mac with Time Machine or another method . While these deletions are generally safe, a backup gives you peace of mind. How to Delete Temporary System Files from /private/var/folders/:

This is where macOS stores temporary data that apps are actively using. This folder can grow surprisingly large.

• Go to /private/var/folders/
• You'll see folders with random-looking names
• You can delete the contents inside the C and T subfolders

It's better to delete only the dated folders, not everything at once

The safest approach: Instead of manual deletion here, simply restart your Mac. macOS automatically clears out many temporary files during a reboot. One user reported that a simple restart freed up 50GB from this location!

If you're trying to clear junk file for Mac and you've noticed that your "System Data" is mysteriously huge, there's a good chance the culprit is something you've never heard of: Time Machine local snapshots. These are hidden backups stored directly on your Mac's internal drive, and they can take up a significant amount of space—in some cases, dozens of gigabytes.

Because these are backups of your recent changes, deleting them means you temporarily lose the ability to restore a file you might have accidentally changed or deleted in the last 24 hours. It's highly recommended that you connect your external Time Machine drive and run a fresh backup before proceeding. This ensures your data is safely stored elsewhere.

How to Manually Delete Snapshots:

Step 1: Open Terminal

Step 2: List Your Hidden Snapshots

Step 3: Delete a Snapshot

Step 4: The Nuclear Option (Disable Completely)

After deleting the snapshots, check your storage again (Apple Menu > System Settings > General > Storage). You should see the "System Data" or "purgeable space" has significantly decreased, meaning you've successfully used this method to clear junk file for Mac.

If you're looking for a powerful, completely free way to remove junk files on Mac, the open-source command-line tool Mole is an excellent choice. Think of Mole as a digital Swiss Army knife for your Mac. It's a free utility that you run directly from the Terminal (your Mac's command-line interface).

It's called "Mole" because it digs deep into your system to find and clear out hidden junk files that you might not even know exist.

Step 1: Install Mole

The easiest method is by using Homebrew (a package manager for Mac). If you don't have Homebrew, you can install it first, but it's a quick process . Open your Terminal app (found in Applications > Utilities) and run:

bash

brew install mole

Step 2: Run a Safe "Dry Run"

Before you actually delete anything, it's wise to see what Mole plans to do. To preview exactly which files the cleaner will target, use the -- dry- run option:

bash

mo clean -- dry- run

Step 3: Perform the Cleanup

Once you've reviewed the preview and are ready to proceed, simply run:

bash

mo clean

You might be prompted for your system password (using sudo), as the tool needs permission to access certain system files. Mole will then scan your system and remove junk files on Mac.

How about using the built-in storage management tool. The tool is hidden in your System Settings, but it's easy to find. Follow these steps to start clear junk file for Mac:

1. Open Storage Settings

2. Follow the Recommendations

Once the Storage page loads, look for the Recommendations section . This is the most beginner-friendly part of the tool. You will see a list of quick actions you can take with just one click. For example, it can help you:

• Empty Trash Automatically: Automatically erase items that have been in the Trash for over 30 days.
• Optimize Storage: Remove movies and TV shows you have already watched.
• Reduce Clutter: A button that helps you find large files and old documents you may have forgotten about.

This method is the safest way to clear junk file for Mac if you are a self-described newbie. Apple designed the "Recommendations" section specifically to prevent you from accidentally deleting important system files. It only suggests removing items like cache files and old Trash items that are safe to erase, giving you peace of mind while you learn how to maintain your computer.
