If you’re using a MacbookPro or Air for quite some time, you might notice that your laptop’s performance is not as good as it was the first couple of times you used it. Now, before you go out and buy another Mac, you should know that the issue is totally normal and can be fixed.
Your Macbook’s slow performance can be attributed to the amount of junk accumulated in your laptop with all the data and files you go through every time you use it. Over time, your hard drive gets filled with all kinds of junk data, like caches.
In this article, we’re going to talk about caches, how to remove them from your Macbook Pro or Air, and list out several ways to on how to do that.
What Is Cache?
In layman’s terms, a cache is a set of technical data created whenever you use applications or browse the Internet on your MacBook Pro or air. Their primary function is to enable and expedite MacOS operations so your laptop could work faster.
Apple states that cached data on your Macbook Pro or Air speeds up the data user store in iCloud and the downloading of Apple software by “saving content that local Mac computers, iOS devices, and Apple TV devices have already downloaded.”
And that cached data is “available for other devices to retrieve without going out over the Internet.”
There are three kinds of cache files:
- User cache
- System cache
- Browser cache
Why Should You Delete Macbook’s Cache?
Although cache files are useful in speeding up your Macbook’s processes and tasks, they have a tendency to pile up until they overcrowd your system’s folders. And once they do, that’s when your Macbook becomes slower and sluggish, resulting in poor system performance.
Deleting your cache is one of the first things to do when you want a disk cleanup. They may take up only a small amount of space, but over time they can grow over to hundreds and thousands of megabytes.
It’s really advisable to delete the cache stored on your Macbook now and then so you won’t have to deal with some issues like some data becoming corrupted, affecting other apps, and system performance.
How To Clear User Cache and System Cache
When it comes to the caches stored by the several apps you use on your Macbook, you can choose to delete them manually or automatically.
All the caches of any used apps are stored in the system Library or user Library folders. So if you want to delete every cache manually, that’s where you can find all the junk you need to clear.
If it’s your first time doing this, make sure to always back up a copy of all the contents in every folder you intend to delete in case something goes awry. Please take note that you should only remove the contents of the folders, not the folders themselves.
