How To Clear Cache On Macbook Air

How to clear cache files on Mac

Cache is basically a technical data that is stored when an app, browser or system performs a task. Cache files serve a vital function as they contain a "shortcut" to a task in order to perform it faster the next time.

Why should you clear cache on Mac?

Cache is meant to help your Mac load sites faster, but sometimes it brings more harm than good. For example, if the website you're about to visit has been updated ever since your Mac cached its data, your browser will still load the outdated cached version of the site. The outdated cache may be the reason why some websites behave laggy.

Old cache files that remain latent in the system do nothing but piling up, cluttering your system folders. What was initially useful becomes a drag, slowing down your Mac through all the wasted space it is taking up. To make it even worse, undeleted cache data also leads to task conflicts and other system issues.

It's staggering how much space can in fact be occupied by app/user cache on Mac. Wondering how much storage you've lost already? Well, it's different for everyone, but it's safe to assume several gigabytes at the very least.

Here are the three main categories of cache data:

Browser cache
System cache
App (or User) cache

How to clear all types of cache on Mac step by step

Now, if you're ready to finally get down to business, we're going to walk you through both the manual and the automatic solutions to clear your cache.

To play it safe, back up the folders mentioned in the steps below. If everything works as it should, you can later delete these backups. Or you can skip the manual steps and go straight to Quick Tip (the safe and easy method).

1. Clean app cache on Mac manually

To delete app cache (which is also called user cache) manually, follow these steps :

How to delete system cache files manually

Open Finder and select Go > Go to Folder
Type in ~/Library/Caches and hit Enter
Backup the folders if you are worried about something going wrong
Keep the folders, but go into each one and delete the files inside

2. Delete system cache

System cache doesn't take much space, and it's usually files generated by OS. You need to be particularly careful when clearing the system cache manually to avoid erasing vital system files.

To remove the system cache completely, follow the steps above , but this time go to /Library/Caches (without the ~). Don't delete folders: you can only clear what's inside of them. When you're done, just empty the Trash to finish the job.
