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 The outdated cache may be the reason why some websites behave laggy.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:

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.

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.

3. Clear Internet cache on Mac

Clearing browser cache has two good things about it: it frees up space for your Mac to run faster and it removes your browsing history, making sure nobody ever finds your digital trail.

If you’re uncomfortable deleting cache manually and prefer a less time-consuming approach, you can skip down to “How to clear all browser cache easily” to remove all your browser caches in one go.
