When our storage starts running out, the first thing that comes to mind is to delete somethings and free up more space on Mac. Most of us delete files that you would have kept to make more storage to your Mac. Even though you don’t want to delete any file, you have no choice when your Mac is full of gigabytes. But do you know you can make several gigabytes of space on your Mac without having to delete your valued files? If you don’t know, the good news is that you can delete the cache on your Mac instead of some important files. In this article, I am going to show you what cached data is, how to clear cache files on Mac, and how to clear cache files in the browsers you are using.

What Is Cached Data?

What are caches on Mac? Cached data is simply the files, images, scripts and other media files stored on Mac by websites or apps. This cache responsibility is to ensure an easy entry to load a website or launch an app when you are trying to access it again. The good news is that nothing will happen if you delete cached data. Once you clear cached data, it will recreate itself whenever you access the website or the app again. There are roughly three main types of cache files you can clean on Mac: system cache, user cache (including app cache and DNS cache), and browser cache.

How to Clear Cache Files on Mac Manually

The second way to clear user cache is that you can clean up the user cache manually. Follow the following steps and clear your cached data by yourself.

Step 1. Open Finder and select the “Go to Folder“.
Step 2. Type in “~/Library/Caches” and press enter.
Step 3. If you are afraid of losing anything important or you don’t trust the procedure you can copy everything in there to a different folder. I don’t think it is necessary because what’s the point? Clear cache to free space up and occupy that space with the same cache only this time on a different folder?
Step 4. Clear every folder step by step until you get enough space that you want. The best way is clearing what is inside the folders instead of deleting the entire folders.

It is important to empty the Trash after you delete the cached data. This will ensure that you get the space you were intending to get. After you empty the Trash, restart your Mac. Restarting your Mac deletes cluttered debris that is still taking up space.

How to Clear System Cache and App Cache on Mac

This cached data is usually created by the apps running on your Mac. App cache helps the app load faster every time you try to access it. Whether you need the app cache or not, it is up to you, but deleting it does not mean it will affect the performance of the app. Deleting the app cache is done almost the same way you delete user cache.
Step 1. Open Finder and select go folder.
Step 2. Select the go folder and type in the library/cache.
Step 3. Get inside the folder of the app you want to delete app cache and delete all the cached data inside the folder.

Note: Not all app cache can be safely cleared. Some app developers keep important user info on cache folders. So using Mac Cleaner to clear cache files on Mac would be a better choice.

You should be careful when deleting app cache because some app developers keep important data on the cache folder and deleting it might lead to the poor performance of the app. Consider copying the folder somewhere else, delete the app cache folder and if the app works just fine, delete the backup folder too. Make sure to empty the Trash after you delete app cache.
