How to Clear the Cache on Mac to Free Up Space

All computers, including Mac laptops and desktops, contain temporary cache files that are meant to accelerate certain processes, including loading times for websites and apps. However, cache files can accumulate over time, taking up valuable space on your disk drive and actually slowing your Mac over time. Leaving behind too many cache files can also pose a privacy risk, as they can be used to track your online activity. This tutorial demonstrates how to routinely clear the cache on your Mac to prevent system slowdowns and limit privacy risks.

How to Clear All Types of Cache on Mac

Before jumping into learning how to clear cached files on a Mac, we recommend you create a backup of the important files and folders. This is a crucial step, as it will provide peace of mind in the event that something goes wrong. After everything goes as planned, you can remove these backups.

Clear the Mac User Cache

Follow these steps to clear the user cache on Mac:

• Click on the “Go” Menu at the top of the screen and select “Go to Folder.”

2. Type the following command and select “Caches.”

~/Library/Caches

• Right-click on the files you want to remove and click “Move to Trash,” or select all the files, right-click on one of the folders and select “Move to Trash.”

Clear Application Cache on Mac

Deleting the application cache on Mac is unnecessary, as many of these files help programs load faster. This is similar to cleaning the system cache. However, if the app is bugged or you just need to clean this folder to open some space on your Mac, follow the steps below:

• Open “Finder,” choose the “Go” menu, and click “Go to Folder.”

• Type the following command:

/Users/[UserName]/Library/Caches

• You can see the user caches for all apps in this window.

• Choose the folder you want to delete or open the folder and select the files inside. Drag them to “Trash” or right-click and choose “Move to Trash.”

One of the best ways to resolve website loading problems and errors is to erase the cache on your browser. Follow the instructions below to clear the Safari cache on Mac:

• A new “Develop” option appears in the menu at the top of your screen. Click that and choose “Empty Caches.”

Clear the Google Chrome Cache

You may wish to clean the cache in Google Chrome for the same reasons you would in Safari or any other browser. Do so by following the instructions below:

The steps to clear the Firefox browser cache are very similar to Google Chrome. Follow the steps below to clear the Firefox cache on a Mac:
