How to Clear Cache on macOS High Sierra

Written by Techsviewer

You have probably heard that one of the best ways to speed up your Mac is to clear its cache. But what is this cache? You need to understand what it is and why clearing it will help speed up the Mac before you go ahead and start clearing it. The cache is the type of memory where data is stored so as to make it easily available when it is needed by the macOS High Sierra. Cache memory provides information much faster than the other kinds of storage. Caches can hold data that is also stored elsewhere in the Mac leading to duplication. It stores technical data when a browser, app or system operations are carried out.

The cache will remember this and the next time the action needs to be done it will be done faster. While a cache hastens the speed with which data in the cache is accessed, when the cache is too full it makes the Mac sluggish. Now that you know what it is, you should know that choosing to clear cache on macOS High Sierra will boost its speed.

Types of Cache in Mac:

In every Mac there are three different kinds of caches each with different functions. They are:

Browser cache: almost every Mac user knows this. It is where the browser stores information about the website visited and the data from those websites. Clearing this cache has two benefits. One, which many are familiar with, is that it secures privacy and second is that it frees up storage space.

System cache: this is data that is created by the macOS High Sierra’s system files and operations.

App cache: this cache contains data that is generated from the use of applications. These include third-part apps as well as apps made by Apple.

Now let us look at how to clear cache on macOS High Sierra. There are various methods and we will walk you through all of them.

1. Clearing Mac Cache Manually

To clear Mac cache manually means going to the cache and actually deleting the contents. This method applies for system and app caches but not browser cache.

Go to Folder on macOS High Sierra

Step 1: Open Finder and then select “Go”.
Step 2: Click “Go to folder” and type: “~/Library/Caches/”.
Step 3: You will see the all the cache files stored in the Mac. To delete certain caches, search for them on this folder and remove them. For instance, to delete safari cache files open the come.apple.safari folder and search for cache.db and delete this.

This method does work but it has a few challenges. One is that you cannot be sure of the files to delete and which to leave. There is the risk that if you delete some caches the Mac may freeze or the system may crash. The space the caches take is also not clear and deleting some may have no impact on the Mac’s speed.

Step 4: empty the trash to create the additional space in the hard drive by completely removing the caches. How do you empty this Trash? Hold the control key and click on the Trash icon in the dock. Choose “empty trash”.

2. Clear Safari or Chrome caches

While surfing the website, a lot of information is stored in the browser cache. This stores temporary website data for faster browsing when a website is revisited. Clearing this cache will delete browser history and this will protect your privacy and it will also clear up storage space.

Each browser is different from the other and so is the process of clearing its cache. In Safari, the place to look is in Privacy while in Chrome, it is in the settings.

To clear Safari browser cache on Mac:

Step 1: Open the browser and look at the top menu. Choose “Safari”.
Step 2: Click on “Preferences”.
Step 3: Click on the “Advanced” tab.
Step 4: Enable the “Show Develop menu” in the menu bar.
