How to clear cache files on Mac

So, you’ve heard you need to clear cache files on Mac. But you only have a vague idea why and you can’t even pinpoint exactly what cache files actually are. So before you start deleting, you must understand why and what you are removing. Cache files are both extremely necessary and utterly useless after a while, as they become a storage killer, dragging your Mac’s performance to a laughable speed.

How come? Read on to find out everything about cache files and how to clear them to regain your Mac’s full capabilities.

What is cached data?

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.

How much space is Mac cache taking up?

The answer is: it depends. However, with so many types of cache data, chances are a lot of your vital storage space is going to be eaten up. Here’s an overview of the three main categories of cache data:

  • Browser cache – this is the most common type known to almost every Mac user. The browser stores cache data from websites you visit, including your browsing history. Many users clear their browser cache to primarily secure their privacy, not realizing they are also freeing up essential space.
  • System cache – this is the cache data created by the built-in system services that run your Mac’s OS.
  • App (or User) cache – finally, this stands for data created by all the apps that you use. It includes apps that came with your OS (like Mail) as well as third-party apps (like Photoshop).

Why should you clear cache on Mac?

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. And this is not anyone’s idea of a healthy Mac.

Take the example of browser cache. Browsers cache images from visited websites to load a site faster the next time you visit it, escaping the need to download the images again and saving you time. But that’s only temporary, because in the long run, undeleted cache files will do the exact opposite, slowing your Mac down.

App caches have the most storage-saving potential – it wouldn’t be surprising to clear up gigabytes of space when cleaning app caches. As to browser cache and system cache, they are smaller in weight, holding some dozens of megabytes. Yet, in some cases they may take up up to several gigs.

Cleaning app cache and system cache on Mac

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. System caches doesn’t waste that much, yet they are still “heavy” enough. Luckily, you can clear the both types in the same fashion.
