How to clear cache on Mac



Many of your daily computer activities (such as opening programs, logging in to email and browsing websites) are saved as temporary files on your computer. Caching is called caching and “helps reduce Internet data usage and speed up software installation on Mac computers, iOS and iPadOS devices, and Apple TV.”

For example, when you visit a website, the browser will download data such as images, scripts, and login credentials, and save them all in a cached folder. In the future, when you visit the same site, the browser will only (quickly) load data from the folder it has created. In this way, your computer does not have to spend time downloading all of this information again, it only needs to extract the information from the cache.

There are several different types of cache data: user or application data used to save certain application information; system cache, your operating system is used to save process information; and browser cache, which can save your web browsing activities.

Is it convenient? But it is important to clear this cached information from time to time to ensure data security and free up disk space, which helps the operating system run more smoothly. If you encounter problems with certain applications, you might also want to clear the cache.

This is the way to get the job done. (Please remember: After clearing this data, you may find that when you visit certain websites, you need to enter your credentials even if you didn̵

7;t need it before.)

How to clear system cache on Mac

The system cache does not occupy the space of the application or user cache. These are usually files generated by the Mac operating system, which means you should be careful when choosing to delete content. You don’t want to accidentally delete important files that make the system work properly.

If you know what you are doing and the specific system folder you want to clear, follow the methods below to access the system cache.

  • In the Finder window, press the shift key, Command and G keys.

  • The “Go to Folder” window will pop up. Enter the following command in the search box: /Library/Caches (without the ~ used above). You can also access this command by opening Finder and navigating to “Go”> “Go to Folder” from the menu.
